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
