I finally did it, thanks to this Zwave battery operated switch. Here’s a video of it working with the guts exposed. And of course let’s make sure the thing turns off automatically. My nest is just a few feet away, so I’ll probably add an automation to detect a high temperature spike to set off some alarms or notifications just in case the switch fails to turn off. Screw code. No more getting up to look for the remote.
