Support of DS18B20 temperature sensor

[Skusi]

Hello,
I've had my Mitsubishi air conditioner running since yesterday and this interface works great with my Fhem system. Many thanks to gysmo38 !!! (coffee is coming!!!)
I run the sketch on a D1 Mini 8266 and would like to connect 2x DS18B20 temperature sensors to it to measure the air in and out temperature of the fan. The actual heating output can then be calculated using the values ​​together with the active fan stage and the air volumes specified in the data sheet.
I'm doing this now with a separate D1 mini. It would be nicer if I could connect the sensors to the same D1 mini,
to transfer the values ​​to my Fhem via Mqtt. Or you could also include the calculation in the sketch and then display the heating output and send it via Mqtt.

Would that be possible ? Or do I have to revive the second D1???

Greetings Skusi
