It works just like you
It works just like you would want it to, which is perfect. Started working as soon as I installed the batteries (see below). I have the remote display in the kitchen, ranging from 30-50 feet (9-15 meters) from the pool thermometer (depending on where it is in the pool as it circulates) and always works. Checked the temp against another thermometer and it’s the same, so seems accurate.
Only suggestion I would have is to add to the instructions to try changing the channel if the remote doesn’t display right away. I waited the suggested 15 minutes for the remote display to connect but wasn’t getting a reading. I reinstalled the batteries and still no display. I clicked to channel 2 and the temperature displayed immediately.
