  Suggested limits. A person must confirm every limit before this device can be written.
  Turn on MQTT and status notifications in the Shelly settings, then replace aabbccddeeff in each topic
  with the device id. Set host to your broker. On battery the sensor sleeps and reports about every two hours
  or when a reading changes, so a reading can stay unknown until it wakes.
