In regards the simple Feed Mode using the MobiusBLE library.
The sketch I posted before isn't working properly, but the one down below was just tested and is working for me.
Let me explain the idea:
The sketch uses the HA/MQTT auto discovery function.
during boot, it will publish 2 initial JSON messages so the HA component can be created automatically:
homeassistant/switch/mobiusBridge/config:
and
homeassistant/sensor/mobiusBridge/config:
It will then send the Feed mode status and the quantity of Mobius Devices found:
homeassistant/switch/mobiusBridge/state: OFF
homeassistant/sensor/mobiusBridge/state: {"qtydevices":2}
Ideally, this should auto create the component in HA similar to the below:
To enable/disable Feed Mode, just turn on/off the "Feed Mode" switch.
Although the switch is now reflecting the new state, please note it takes time to scan and set the scene, but you can monitor the execution using the arduino Serial Monitor.
and lastly, use it at your own risk as I'm not a programmer and this was coded as a simple proof of concept based on @thetastate initial idea and no extensive test was executed.
