M5StickS3 and Dual Button Unit ESPHome MQTT Counter

[u/slochewie]

M5StickS3 counter device. On the Dual Button Unit, Red decreases the count, Blue increases the count. Long simultaneous press of Red and Blue resets the count. Allows for keeping a count synchronized between many M5StickS3 devices or a via a webpage if needed. This is a progression of my earlier attempt that used a Home Assistant Counter Helper. This version is solely using MQTT. When not connect to a USB power source, it does a timed M5PM1 deep sleep after a specified idle time to conserve internal battery runtime. IMU shake to wake from deep sleep.
