If you're still in the market, the HestiaPi has this feature. You decide how far off from the set points is tolerable.

I approve

HestiaPi

Yes. It can be used without network capabilities. The software works with an ethernet connection using a USB on-the-go adapter and USB ethernet adapter, and that's how I do development. Unfortunately, there is a mechanical limitation that prevents the models that I make over ethernet. The connector for the LCD screen blocks access to the USB micro port. If you go without a screen, you could use an USB ethernet adapter. It'd be pretty weird to have a thermostat with no UI and it'd put you in a weird situation where a network outage would stop you from adjusting the thermostat, but it's doable. In summary you've got three options for a WiFi-free HestiaPi: - dumb thermostat - screenless thermostat - DIY hardware and using the HestiaPi software By default the pi will serve up a wifi access point for the initial setup, but if you hop on the community forums, we can help you disable that.

What do #Nest owners think about #Google's decision to not only kill support, but also make the smart thermostats into dumb thermostats? Is it fair for them to take away the features you paid for? Will you get another smart #thermostat from the same company again? Are you in the market for alternative #smart #thermostats? #IoT #tech #technology #PlannedObsolescence #waste #recycle #repair #repurpose #reuse
