Hi Guys,
I am really new at this so some of my questions may seem stupid. I seem to have run into an issue with my thermostats creating bad radio waves which interfere with my system. I currently have a Vera2 on 3.2 and about 25 switches as well as 2 CT22 thermostats. It was rock solid for a couple of months until a few days ago when everything just stopped responding. Tech support thinks it’s radio interference caused by the thermostats. I can see all the nodes and my events are running as scheduled, but I cant control or communicate with anything. I have restored backups and tried healing to no avail. I would like to install the Filtrete 3M50 thermostats because I could control them via wifi if vera craps out again. I need UI5 to run that plugin. I currently run my Vera2 in bridge mode off my Airport Extreme. What I am wondering is if I can buy a Vera Lite, run it as a slave to the Vera2 and just put the thermostats on the Vera Lite. That way, (I hope) I can disable them from the vera2 and run them via wifi if they create issues again.
Any ideas here? Oh and yes, it WOULD be easier and cheaper to just turn off or reset the thermostats when they do that, but the house is being run remotely and it’s a 19hr drive… 
A couple of people have had similar issues. It is most likely due to interference. I would first remove power from the thermostats. See if things respond. The few that had similar issues traced it to their thermostats going into a weird state and flooding the z-wave rf with noise. Lets try these simple things first before we have you spend money. I would also check your switches as well.

Thanks for the reply! I have someone who can go in on Monday. Can he just turn the thermostats off or does he have to cut the power at the breaker? They have batteries in them. What about resetting them? I could then leave them out of my network for a couple of weeks and see how it goes… :-\
Are they fully battery powered or do they also have a common wire connected to them for power? I would remove the batteries and the common wire if attached.

They have a common wire and batteries.
If its a matter of flicking a switch, I can ask this guy to do it. Anything more than that I should probably do myself and it will be a few weeks before I can go. What if he pulls the batteries and then flips the main breakers for the whole house? I have been doing some reading and it seems like the thermostats just need a reboot of sorts to get them behaving again. Would this effectively reboot them?(along with everything else) Or is it better to cut power to the thermostats while leaving vera on?
Well cutting the breaker to the whole house will power everything off. Could reset any of the devices acting up. Also removing the batteries will need to be done as well.

Welcome!
I’d see if you’re guy could take the batteries out and disconnect the C wire. First one thermostat, check communication, then the other.
Not sure if adding a second Vera would help. If it’s really some kind of interference, then perhaps nothing in that frequency band will work reliably?
