I think you need to check the examples on hot to use dht sensors because I'm not sure if you can instantiate only one dht object if you have 2 sensors.
In addition I'd use more reliable sensors than DHT like sht31 or si7021.
Locking this topic to aviod unnecessary double work and confusion since the same post was made at https://forum.mysensors.org/post/71293
Pleas don't post the same question multiple times.
