Wondering if anyone has thoughts/advice on my situation with the relay I have installed to control my water heater. Read all the forums on CA3750 and couldn't find any help.
I have the CA3750 220V 30A relay wired in my basement, and vera edge is not far away (~15ft). Others have mentioned the signal issues based on the antenna placement within the CA3750, but my signal is fine and after pairing to vera I can reliably control with 100% success rate.
When I run into trouble is during a power outage. The Z-wave board is powered by the 220V -- great no batteries, and when the power goes out, I expect nothing to work.
When the power comes back (could be just a brief outage), the relay is always off -- also fine, I can create a scene to detect this situation and flip the relay on.
But... what happens with my CA3750 is that after a brief power outage, it is no longer paired to my vera edge! I need to go downstairs and go through the whole exclusion and inclusion cycle again. Since this is a vacation home, I am not there very often to perform these steps, and apparently our power provider flickers like once a month.
I don't know a whole lot about the vera pairing process, but is this expected? My battery devices and other AC devices "remember" their pairing to vera when they are disconnected from any power source. Bug in the version of UI7 I am running?
Please help. I'll have to remove this relay to ensure consistent power can be applied to the water heater.
