Temperature in sauna

Question regarding solution for checking temp in a sauna… I plan on having a Fibaro smart implant and a ds18b20 cable…

Is there anything else to be aware of or should this simply work?

Don’t forget a stable power supply.


Connect first the DS18B20 and only then include the smart implant into Homey.
Else, external temperature will not be shown.


Any advice on what power supply to buy?
