I’m a fan of MQTT. I use it with zigbee2mqtt, Shelly H&Ts and for some custom projects. I originally used it for my Shelly 1s but eventually flashed them with ESPHome to get more control and flexibility.
One potential advantage of ShellyForHass is firmware update notification with actual updating on command.
I just set up some Shelly RGBW 2s today. I came across both ShellyForHass and the impressive Shellies Discovery Script https://community.home-assistant.io/t/shellies-discovery-script in addition to old school MQTT.
I configured the Shellies with the official app with both cloud and MQTT turned off.
After my original post, I decided to give Shelly ForHass a try. Installation with custom_updater couldn’t have been simpler. After a restart, the devices were automatically discovered and had entities created. All of that happened in the background. Some visibility and notification of what’s happening would be preferable. But, it worked and everything was set up properly. It’s very early days but so far, so good. I’ll update this thread as warranted.
