Opal Nugget Ice BLE Integration

Home Assistant BLE Integration for FirstBuild Opal Nugget Ice Maker.

I am still working on adding switches to turn on/off light and icemaker. If you want switch capability, use the ESPHome code posted below. I am using the ESPHome code right now as has more functionality.

This might work for the GE Branded model, not sure. Mine is the OG FirstBuild version

Installation Instructions

Add this repo into HACS
Install integration
Restart Homeassistant
Wait a few minutes and HA should find it automatically
If not found automatically, Go to Settings->Device and Services->Add Integration (blue button at bottom right) -> search for Opal BLE
It should find it and set it up

Another option is to use ESPHome (but less effecient). However, this supports switches
