READ THE CHANGELOG BEFORE UPDATING!
which is the chepest way to manage temperature sensors with MM ? I mean, I’m searching cheap hardware sensors to retrieve temperature in one or more rooms
@s-monti-74 If you’re only looking for cheap temp sensors only (so only measuring and not controlling), you should go with the DHT11 or DHT22
I guess it will not get cheaper, but of course wiring and coding is necessary.

I have just installed a DS18B20. I bought it for €0.85, complete with wires. But you need to get a 4.7k ohm resistor, which is not expensive. It is not waterproof and it does not read humidity. It is just a thermometer. Very straightforward installation.
OK but I would measure the temperature of various rooms, so I was thinking about wifi or zeegbee sensors without using the gateway or a cheap gateway
zigbee does need a gateway since it talks on another protocoll than regular wifi (even if it is on the same bandwidth).
try building esp8266 nodes with temperature sensors and run espeasy on them. should cost you around 10-15usd each, without power supplies.
otherwise you have ready made Shelly Temp Sensors that runs on wifi, they are a bit pricey though.
esp temperature build guide :
@broberg Not bad the “Shelly solution” but with which module can I read the values ?
@s-monti-74 Don’t think there are any modules written for shelly yet. It’s not impossible but don’t think anyone have done it.
Same goes for the esp8266, don’t think there are any modules for temperature for those either.
