“RasPi0 with WiFi - and the WiFi works well - even with thick stone walls at home (better than the PasPi3 even). No more dongles, perfect for distributed control and sensing! Works well as a camera platform too ("motion" plus Synology NAS).”
“I turned my new Pi Zero W into a wireless garage door opener switch and monitor for use with MQTT within Home Assistant. Can't beat the price and can't beat the performance!”
