I have had several pool sensors from Oregon Scientific (3x THWR288 en 1x THWR800) and all of them broke after using them for 12-18 months due to water leakage. I was hoping the THWR800 was better in that sense, but this one still displays and sends the temperature but it now reads 58,7 degrees Celsius in my office

I tried te set it to Fahrenheit but than it's also way too high.
So I gave up on using the Oregon Scientific pool sensors and want tot ask the forum if there is an alternative product on 433 Mhz which compatible with the RFXCOM receiver ?
Thanks,
