I an using one of these for the temp in my fish tank. The temp doesn’t vary much.
Today it has reported as follows.
If the temp hasn’t changed it is reporting the temp every 2 hrs approx.
If temp has gone up 0.1C then I get a report. This is around every hour +/- 10 minutes.
If I remove from the tank and there is a big temp difference then I get a report within 5 minutes.
Try putting it in a cup of hot/cold water. Does it report then?
If it is continually reporting even if there is no temp change will only shorten battery life.
If yours is reporting like mine, isn’t that good enough?
