That makes sense, and probably saves quite a bit on electricity. What kind of smart switch are you using?
We are a (nearly) full blown Home Automation household. I run a Hubitat Elevation hub, Lutron Pro hub (integrated), and am 99% Z-wave and Zigbee devices. It's a craziness/sickness for sure and I'm on the low end of the spectrum. Have maybe one or two WiFi devices just for special device control as having ~85+ devices on WiFi would be unmanageable, unreliable, and decimate the networks - even with a UBNT setup and 3 Pro AP's.
These particular outdoor rated switches are Inovelli (NLA), and I have a mix of 2-channel and 1-chnl/always on receptacles. I use them to control outdoor lighting, the truck, etc. They're basically the same as the GE and some other brands with someone else's brand and code.
Truth be told, I should probably spice up my rule from a simple low temp on/off to something more complex like cycling it and/or using presence and time of day as well. The charger doesn't matter as it will control its own fate.
