We're using a TTN LoRaWAN node to monitor the temperature of the drinking water for cows. The water is heated using fresh cow milk, that needs to be cooled down.
Updates can be found in the API (although the DB has some issues right now):

The first value is the water temp., second air temp., and third the battery voltage (*1000).
