Now that I am getting my MH box online and working somewhat well, and making progress, I'm looking at expanding my system. While I realize it's the coke or pepsi debate, I'm looking at getting weather monitoring hardware added. I would like to monitor tempurature and humidity in all of the rooms of my house. What is the best (best=nice mix between affordable and reliable) hardware for that? Should I go with a bunch of iButtons? Do other people on the list monitor temps in each room, or just a few key rooms? What other cool things should / could I add to my system? I would like to use something that is popular with other list members so that I don't get some unknown piece of hardware and have a hard time getting it working. As for external weather monitoring, I am thinking of something that will do sunlight, temperature, humidity, wind speed, wind direction, rainfall (snowfall?), pressure. Is there something popular that will fit this bill? Thanks. -- -=/>Thom |

Ok, if you want all this, you should go with an rfxcom 433Mhz and oregon scientific weather sensors. You can get temp/humidity/baro in each room wireless for $30 or so (1-wire temp/humidity is closer to $60 and you need to cable it). Outdoors 1-wire stuff exists, but I found it pretty expensive, so while it costs more when you start, going wireless ends up being cheaper in my experience. This explains the rfxcom 433Mhz stuff (it'll cost you around $150 for the receiver): http://misterhouse.wikispaces.com/X10RFX10SecRFXCOM For outside weather, the WMR968 is actually not so bad ($150 to $200) and will get you 4 sensors but 7 readings: - rain - outside wind speed/dir - outside temp/humidity - inside temp/humidity/baro (that's a BTHR968) Then, just buy more BTHR968 for your other rooms: http://www.ambientweather.com/orscbt.html The only trick is that the WMR968 console (which you could use to receive the signals on your PC instead of a separate rfxcom 433Mhz if you want to save a bit), will only receive one BTHR968. So, you must have an rfxcom if you want multiple BTHR968's. We're left fwith sun, I got the 1-wire UV sensor from http://www.hobby-boards.com/catalog/product_info.php?cPath=22&products_id=1567 If you only care about sun, and not UV, you can buy this combined sensor instead: http://www.hobby-boards.com/catalog/product_info.php?cPath=22&products_id=57 (I just didn't need that one since I already have outside humidity/temp). I haven't graphed my oregon stuff (I should do this within a few days), but you can see my 1-wire and UV stuff: http://graphs.merlins.org/graphs/graph_view.php?action=tree&tree_id=2 http://graphs.merlins.org/graphs/graph_view.php?action=tree&tree_id=6 In the end, both 1-wire and oregon scientific will fit the bill, but 1-wire costs a bit more somehow, needs wiring, if you get lightening, you're risking everything your 1-wire is attached to. Oh, 1-wire is however definitely cheaper if you only need temperature since sensors only cost a few dollars each. It's just a shame that the price jumps to $60-ish as soon as you want to add humidity. Good luck :) Marc -- "A mouse is a device used to point at the xterm you want to type in" - A.S.R.

Hi, Thom - yeah, this definitely a "religous debate". I personally have different sensors for different needs - I have two AAG temp sensors ("commercialized" 1-wire) for sensing in my office and our attic; and plans to expand that "network". I messed around for a while with "discrete" 1-wire devices and basically gave up because I couldn't get reliable connections. Then, I have a Davis WMII Weather Station for wind, pressure, temp/humidty and rain. As you can guess from the fact that it's a WMII; I've had it forever. Finally, I have a new 1-wire/APRS weather box (temp/pressure/humidity/wind/rain) from Argent Data Systems that a friend and I are building to go in a remote location. I've had good luck and challenges with all of 'em. One of my biggest challenges is that I'm also an amateur radio operator, and so my home weather instruments are in a "high RF" environment; which can cause all sorts of issues. I've had several ham friends who have had good luck with the Oregon Scientific weather stations; but I personally would be concered about the fact that they're wireless (hence subject to interference). I suppose the least expensive "out the gate" way to go would probably be 1-Wire; but, at least for me, there were reliability/expandability issues there. I think if I had to do it all from scratch, I'd probably still start with the Oregon Scientific as being a good compromise between price and functionality. Hope this helps!

That's a fair point, you could borrow a HAM radio and make sure your 433.92Mhz band doesn't have too much crap on it. That said, I found reception to be flawless at my house. > I suppose the least expensive "out the gate" way to go would probably be > 1-Wire; but, at least for me, there were reliability/expandability issues I disagree with that :) http://www.hobby-boards.com/catalog/index.php?cPath=22 - wind: $140 (95+45) (or some more expensive $225) - baro: $60 - humidity/solar x2 (indoors/outdoors): $120 - rain gauge: $93 then add wiring and a possible hub ($50) Total: $493 to just match what you get with a $200 WMR968.

Hi Thom, according to me it doesn't make sense to monitor humidity in every room. I have a central humidity sensor located downstairs and it seems to pick up the variations in humidity when we shower or clean the house quite well... We do have a whole-house ventilation system however, so the air is already moving around quite a bit. See http://lika.be/uushuus_stats/humi_year.png for a year overview and http://lika.be/uushuus_stats/humi_week.png for the report of the last days. If you are into building your own system: I designed a PCB with ethernet interface where you can connect a onewire bus to (tested with DS1820-alike sensors). I read the values of the sensors over ethernet into an RRD database and I have a separate script that translates the last values entered in the database into xpl messages that are received in MH. Both hardware and firmware is open source (http://code.google.com/p/hasy), and a node with ethernet interface costs ±65 euro. Downside is that you have to solder it yourself ;-) Advantage is that you can add multiple onewire temperature sensors that cost ±3.5 euro of you buy 10 of them. For the humidity, I use an SHT11 sensor. Cost is ±25$ for a single one. Best regards, Lieven.

Hi Thom, Depending on your capabilities and what you want to achieve you can do a lot with 1-wire for not a lot of money. My system is pretty elaborate, weather, solar, temperature sensors throughout my house from the freezer to the attic. I just have one humidity sensor inside which I believe to be fine for my situation. I use OWW for reading my sensors and passing them to misterhouse via socket programming. I use the data to control fans and lights. I also store the data in a MySQL database for historical reference and use RRDtool for graphs on my web page. If I had to do over again, I would bite the bullet and by a Davis weather station. I would still have some 1-wire temperature sensors since they are so cheap, around $4.50 each. My 2 cents worth.

The cost of the OneWire systems fundamentally come down to the interests or willingness of the individual to do electronics. If someone has some reasonable skills then it can be very inexpensive, and unique sensors can be built. Buying the OneWire modules that plug together is about 10X the cost. For those that make their own some with understanding of reliability can yield a pretty solid network - for example mine provides the data to control my pool depth and temperature, and gives me very sensitive temperature analysis for a molecular film pool cover performance.

It pays to check beforehand and the information can be a little difficult to come by. The RFXCOM 433.92MHz receiver will (I believe) receive protocols for all sensor models currently available, so you will probably have a greater selection of sensors to choose from. There's one catch: Even with the RFXCOM (and depending on your tolerance level) the total number of Oregon sensors may be limited to about 16 and you'll have to purchase models of different types to achieve that. (That number is based on my analysis of 23 different sensor models for which I have interval data, and some of them in that calculation are out of production and may be difficult to find.) Here's why: Each sensor transmits at a fixed interval generally between 30 to 90 seconds. Sensors with a channel selector transmit at an interval determined by the channel switch. The interval timing is fairly accurate to the fraction of a second, but as each sensor has its own independent timebase, the intervals for two similar sensors will never be exactly the same. The result is that with two sensors transmitting with the same nominal interval, the slightly faster sensor will eventually catch up with the slower one and there will be RF collisions during which the receiver will be unable to distinguish valid signals from stray noise. So although two similar sensors may coexist for months at a time, there will eventually be a "blackout" period which may last weeks or months, or until one of the sensors is reset and the transmissions are again far enough apart. So the trick is to select sensor models and channels so that no two transmit at the same interval or at an interval which is an integer multiple of another interval. Or you can just say the heck with it, be aware of the problem, and be ready to reset a sensor if a transmission hasn't been received for some time. :-) (X10 security sensors don't have the above problem because the heartbeat interval varies randomly by +/- a few seconds between successive heartbeats.) BTW, the relative humidity accuracy of Oregon humidity sensors drops off the cliff below about 20%-25%, so can be worthless in a heated house in winter which has no humidification system. Are 1-Wire humidity sensors better? Regards, Charles Sullivan |

I believe they are, although there are at least 3 different DACs supported by owfs, so hopefully at least one of the 3 kinds is good :) I'll find out this winter if my house in CA gets below 20% humidity.

So I was inspired by this thread to go ahead and get the rfxcom 433MHZ receiver and some Oregon Scientific sensors. I am using the rfx-xpl gateway from iranger.com and then broadcast those as XPL for MH to pickup. I have successfully populated a couple of the variables in the weather hash and have indoor temperature and humidity. My problem is the value is the temperature in celsius, but I would like it in Fahrenheit. It seems that the rfx-xpl gateway gets both value from the sensor, but then sends the celsius via XPL where misterhouse grabs it. I don't see that this is configurable anywhere. I did see where I can change the weather_uom_temp in the ini, but thats not what I want to do. I would rather get the fahrenheit value directly into MH. I can also already see perhaps an issue with the barometer, the value being collected by rfx-xpl is hPa instead of inches. Any help would be appreciated.

I'm not sure you can send the same value twice, but it's not very hard to convert. Or maybe Greg Satz can modify rfx-xpl for you or give ou an existing option to broadcast the other unit. If you need to convert, hPa to inHg is my $inhg = sprintf("%5.2f", $pres / 33.8639); Marc -- "A mouse is a device used to point at the xterm you want to type in" - A.S.R.

The rfxcom device receives the temperature in the units that the sensor transmits them. The xPL message contains a units field to convey that detail so the xPL final destination can deal with it. I thought about doing the conversion in the rfx-xpl gateway but decided against it as the gateway might not do the conversion properly thereby leaving the receiver with less then desired precision or possibly even needing to do another conversion if I guessed wrong. It sounds like mh may need a units conversion layer. I am uncertain if this should occur in the xPL "transport" layer or further up the stack closer to the temperature/barometer handling? Alternatively depending on what you want to do with the data, you could store the celsius values and do the conversion in the graphs. This is what I do.

Hi James, As best as I know it, the Oregon sensors only sends their data in Celsius for temp and hPa for barometers. There are functions in MH to convert these to Fahrenheit and MBs if that is what you wish before you populate the Weather hash. I think they are in Weather_Common.pm. From: James Ledbetter [mailto:le...@gm...] Sent: Saturday, August 21, 2010 10:52 AM To: The main list for the MisterHouse home automation program Subject: Re: [mh] Expansion to Weather & Temp Sensors So I was inspired by this thread to go ahead and get the rfxcom 433MHZ receiver and some Oregon Scientific sensors. I am using the rfx-xpl gateway from iranger.com<http://iranger.com> and then broadcast those as XPL for MH to pickup. I have successfully populated a couple of the variables in the weather hash and have indoor temperature and humidity. My problem is the value is the temperature in celsius, but I would like it in Fahrenheit. It seems that the rfx-xpl gateway gets both value from the sensor, but then sends the celsius via XPL where misterhouse grabs it. I don't see that this is configurable anywhere. I did see where I can change the weather_uom_temp in the ini, but thats not what I want to do. I would rather get the fahrenheit value directly into MH. I can also already see perhaps an issue with the barometer, the value being collected by rfx-xpl is hPa instead of inches. Any help would be appreciated.

Okay, after a little digging through some of the weather modules, I think I can convert the units just fine. Now another issue. How do go about getting something like total rain fall and rain fall rate. It appears the XPL messages look identical since they come from the same sensor. The same would go for average wind speed and gust wind speed. I have the WRM968 weather station, and it looks like I could use the module for that and get all this info, but I want to keep the console in a location where I couldn't connect it via rs232, hence the reason for the RFXCOM and reading the sensors directly.

I'm not sure about getting them through xPL since I'm not doing that yet, but I'm getting them directly from rfx-xpl: See: http://marc.merlins.org/linux/cacti/ http://marc.merlins.org/linux/scripts/parse_rfx-xpl and http://misterhouse.wikispaces.com/X10RFX10SecRFXCOM#X10RF,%20X10%20security,%20rfxcom%20supported%20RF%20devices%20with%20MR26a,%20W800,%20or%20rfxcom-Misterhouse%20considerations-W800%20with%20mh%20vs%20rfx-perl%26s%20rfx-w800%20vs%20Iranger%26s%20rfx-xpl%20and%20rfxcom%20with%20xpl-rfxcom%20vs%20Iranger%26s%20rfx-xpl Marc -- "A mouse is a device used to point at the xterm you want to type in" - A.S.R.

Pluses: 1) you can receive many more weather devices than what came with the WMR968. 2) you can put the PC and receiver just about anywhere you want Minus: Costs $150 Marc -- "A mouse is a device used to point at the xterm you want to type in" - A.S.R.
