Looking for an easy way to get switch closures to give me an audible signal when closed and provide input to mh. Things I am considering: - input to handshake lines of serial port - PIC or AVR digital I/O to serial connection, possibly through a ddwrt router (have found several similar things on the net that look to be easily adapted). I recently picked up a driveway sensor. I might hook it to unused back door contacts of the doorbell for now but long term I would like to hook it to mh. Have thought of having mh do the doorbell function as well by playing audio files. Leaning towards the PIC/AVR as this would allow future expansion to other things - analog inputs, etc. -- View this message in context: http://old.nabble.com/easy-cheap-way-to-get-switch-closure-into-MH--tp32318599p32318599.html Sent from the Misterhouse - User mailing list archive at Nabble.com. |

Jim- Check out Weeder Technologies. They have a number of modules that use a daisy-chained serial protocol already supported in mh. Digital i/o, analog i/o and some other stuff as well. And they are PIC based, so that fits in with what you were thinking...

I have a duct to outside with a damper on the inlet side of the furnace. My plan was to close off the house returns and pull in outside air with the furnace blower. I planned to automate a couple windows somehow to vent air to the outside and haven't completely figured out that part. I have casement windows so a few gear motors would do the trip (but might look ugly). Have been wanting to do this for a long time. -- View this message in context: http://old.nabble.com/easy-cheap-way-to-get-switch-closure-into-MH--tp32318599p32354194.html Sent from the Misterhouse - User mailing list archive at Nabble.com. |

The problem I see with heat recovery ventilators (other than cost) is that they do a heat transfer between the outgoing and incoming air. This is not something you want to do when the air outside gives free cooling or free heating. It actually slows or reduces the effectiveness of ventilation considerably. They are great when you want fresh air and you are trying to retain as much heat or cooling in the house as possible. Dew point is a much better measure of comfort and availability of free cooling than relative humidity. If the air is 55F and a very high humidity it is still suitable for free cooling. Relative humidity is a very poor indicator of how much moisture is in the air because warm air holds much more moisture than cool air. Dew point measures how much moisture is in the air independent of temperature.

Hi Jim, Well one would think that given their name (HRV). And I was all set to make a summer bypass core for the machine - but first I did some tests and it turns out they don't do that much heat recovery at full speed (boast) when the temperature differential is small (like 15 or 20 degrees F). At normal speed and with the winter outside / inside temperature differential they do recovery a lot of heat. And again because the algorithm is basically temperature bound - e.g. don't consider outside air cooling unless the temperature is lower outside than room temp, and only do so when it is cooling season - e.g. outside air is probably greater than 50 Degrees C. Relative Humidity works out just fine and can be done with a really simple threshold test. Engineering wise - not precise, but really simple and easy to implement if you have a HRV and can bring it under the home automations control.

So how big is the inlet from the outside? Is it a 5 inch piece of ductwork? And then do you just have it on your trunk line which circulates the air in the system? You don't run the furnace fan to help circulate the air? I've been thinking of something similar but was thinking of using something to control opening and closing the windows in the house but this looks like a better solution.

My situation is a bit unusual, I mostl cared about cooling the living room and the main bedroom, which happen to the the only rooms served by ducts under the house (the rest are in the attic). So, I have 2 dampers, to the ducts going under the house. When I close #1 and open #2, those ducts can only pull air from outside. When I open #1 and close #2, they can only pull air from the HVAC system. Then I have 2 booster fans (500CFM) in the ducts going to the bedroom and family room. When the HVAC comes on, I have misterhouse turn on the booster fans to boost HVAC air to those rooms (I wanted that anyway) When I want outside cooling, I change the dampers with mh to point to outside, and turn on the booster fans in the ducts, which in turn will force them to pull air from outside. Outside air comes from 3 registers in my crawlspace (14x4 inches or somesuch) all aggregated into a big 12" round duct.

And another option without the minute by minute resolution is your own utilities smart meter monitoring system.

First, there is no such thing as California :) There is norcal and socal ;) They have one season, we have two. Then, some of my friends within a 50 mile radius don't even need AC at all. Our house does need it, although this has been an unseasonably cool year. Also, note that I have cooling hacks to cool the house with outside air when it's colder than the inside house temperature (I'm just adding the same hack to my garage now). > 2.

The thing is that most of us get totally get raped on electricity pricing here. It starts at 11c/Kwh, and it will jump to 30c/Kwh or somesuch once you hit tier 5 (more than 300% of baseline, which is around 350Kwh/month IIRC). Part of this is that we can't burn coal, and other part I believe is that we have to import electricity from other states that do, and I also think the punitive rates are meant to get people to conserve energy, which I guess isn't all that bad. In our case, we should get the panels paid off in 7 or 8 years for a 30 year lifetime. > Nice LinuxCon presentation, by the way; I browsed through all the slides. Thanks.

Some ideas for those interested in reducing AC. I live in Canada in Eastern Ontario - so we have a supply of cool air outside for some of the evenings even after 80 Degree days in the summer. I just drive the heat recovery ventilator (http://www.venmar.ca/AfficherProduit.aspx?id=2&langue=en) on boost and the central air / furnace fan on low speed circulate. This only is used as a stage one cool and only if the outside humidity is less than 45%. The other thing I have done with my newer Furnace and the Omnistat 2 is implement dehumification control and set the AC temperature much higher - so 76 degrees as the cool point but with the humidity under 45% is very comfortable - and a reduced cost / energy demand during the peak rate period. (One can use the cheap electricity at night to dehumidify). -----Original Message----- From: JimMH [mailto:jsk...@sb...] Sent: August 28, 2011 10:58 PM To: mis...@li... Subject: [mh] Venting the house automagically I have a duct to outside with a damper on the inlet side of the furnace. My plan was to close off the house returns and pull in outside air with the furnace blower. I planned to automate a couple windows somehow to vent air to the outside and haven't completely figured out that part. I have casement windows so a few gear motors would do the trip (but might look ugly).

Hi Guys I've worked really hard to try and figure this out on my own but I'm now at a loss and looking for some help. I just upgraded my OS to Ubuntu 10.04 and upgraded to Asterisk 1.6.2.6 and Freebbx which broke my Caller ID connection to Misterhouse. I'm thinking its probably an issue with the way I have Asterisk and my axc.conf configured. I can see xap messages for voicemail: xap-header { v=12 hop=1 uid=FFE80003 class=CTI2.info source=asterisk.axc.house:vm.default.200 pid=2879 } Messages { readmessages=0 totalmessages=0 type=Voice } and messages showing hook state: xap-header { v=12 hop=1 uid=FFE80002 class=CTI.Info source=asterisk.axc.house:home.telus pid=2879 } Line { Country=1 Dialler=none LineState=free Network=PSTN } but when a call comes in there are no xap messages broadcast with callerid info. Is there any other information I can provide that would help with troubleshooting?
