I have a need to use a WiFi relay to control some stuff. (Also WiFi contact sensor, but that is another topic) The Zigbee and Z-Wave can’t reach into the metal shed some 250 feet away, but I have a WiFi repeater inside the metal shed that works very well.
I have a Shelly in my shed and it works great. I use it to monitor the DC voltage of my security camera backup system as well as one of the relays to reset the cameras when needed
Sorry, I forgot about proper etiquette for asking for help.
I have a C-7 hub with Platform Version 2.4.3.137 so no Bluetooth.
I am looking into the z-wave, but the devices are just so much more expensive. Also there does not seem to be a lot of low voltage stuff.
Since I have a good WiFi connection, I am writing a ESP8266 app. The ESP can respond to HTTP requests, and the Hubitat can send those. But, it is a science project and I just as soon not re invent the wheel. (although my wheel will have nice square corners. LOL) Maybe I make another post asking if someone already has a wheel.
