Check out SONOFF NSPanel Wifi Smart Scene Wall Touch Switch EU/US Smart Thermostat Display on eBay! $40.00 - seems like a super price - BUT, I'm thinking this is strictly WIFI. I thought I had seen a Zigbee version before. Has anyone used one of these with Hubitat?
Cool. Found the zigbee one on Ali, but it's more expensive. Also it doubles as a Zigbee hub and there's also a NS Panel pro, which appears to support matter
