“This is an amazing gadget, fully controllable from shelly app, two switches, two outputs, voltmeter, pulse counter supports full scripting language. Switches are controllable from Google home with voice but you can't read volts via that route, have to use shelly app or web calls using curl etc. Connects to 2.4GHz wifi”
“Got it running to augment our alarms at work. Using it to convert basic beam sensors from using a physical cable to trigger alarms to WiFi to home assistant (still uses the original wire as a backup)”
