Chris, What are you using to detect light level outside?
For me it was very reliable for years, that is until I add my last switch. The new switch would turn on once in a while on it's own. Researching a solution led me to the VeraLite. When I installed the VeraLite I had to disassociate all of the devices from the primary controller and the associate them with the VeraLite. That effectively rebuilt my network and may have been the reason the problem went away. Since it has been 100% reliable and I have also added thermostat to the network.
Misterhouse still plays a role in controlling my Z-Wave network but the VeraLite takes care of all of the Z-Wave protocol. More specifically, I have a scene that uses outside light level and time of day to turn on lights. Basically, two hours before sunset and as the light level drops below set thresholds, MH will send a command to the Vera to ramp up lamps. The lower outside light level, the more lamps ramp up. So on cloudy days the lights come up sooner than sunny days.
Eventually I will try and code it on Vera, I just to many projects going on now.

Did the Z-Wave functionality in MH work properly? (i.e. not buggy)?

>I'd love to hear about this as well. Is anyone using Misterhouse with zwave?
I was one of the very few using Z-Wave with Misterhouse and did so for 4 or 5 years. About 8 months ago I switched to a VeraLite from Mi Casa Verde. I still use Misterhouse but a lot of what it did has shifted to the VeraLite.
Just a few of the benefits of the VeraLite is it works right out of the box. You can write code for it to suite your needs, plus there are a lot of others that can help you with everything from scene scripting to writing in Vera's native language. The main user interface is Web based and can be logged onto via a secure channel with about anything with a browser such as an iPhone.
The Vera is very small, draws very little power, runs Linux and uses Lua as a programming language.
I am not knocking Misterhouse but if you want to go the Z-Wave route on it, you are going to be very much on your own. A Z-Wave USB stick is $50 and no support, the VeraLite $180 on Amazon and plenty of support.
