We have a fireplace that yesterday was on a light switch to turn it on and off. It even has a battery pack (D batteries), so if the power goes out, we can still use the fireplace.
This morning I set this up: https://www.reddit.com/r/homeautomation/comments/3tpxm5/zwave_fireplace_install/ only to be able to turn on/off the fireplace via Google Home AND continue to use the wall switch. We do not plan to use any automations at all with the fireplace.
The new setup is working great! The only issue I see is that if the power goes out, we have no lost the ability to turn on the fireplace with the light switch. I really liked this feature even though we rarely lose power. We live in central Indiana, out in the middle of nowhere, so having the fireplace as a backup emergency heat source is a really good idea.
The only thing I’ve been able to come up with so far is perhaps routing the trigger around the dry contact relay with a simple light switch. So if the power goes off, we pop the fireplace cover off, flip that switch, and we’ll have the fireplace control ability restored, like we could yesterday. I’m not sure my wife will go for this, though (if I’m not home). She won’t be excited about taking off the cover of the fireplace.
What would be great is if there was a switch that routes around the dry contact relay, so that if there was no power, it would be enabled automatically, restoring our ability to use the switch on the wall to turn the fireplace on.
If there was a small enough battery backup, I could put that under the fireplace, but that just sounds dangerous. I’m probably just nervous about nothing, but also I was unable to find a UPS that would fit, so I guess the point is moot.
