No matching function for call 'DHT::DHT()'

[Dick]

First of all 'Happy new year!'. I am working on the example script of the DHT22 https://www.mysensors.org/build/humidity. I read already some other builders about the library (I use version 2.1.1) I already downloaded the the DHT lib from gidhub but still the error as mentioned in the title. Who can help me. I use an Arduino nano.

@dick Sounds like a possible library issue. The example code actually uses a modified DHT library which can be found in the libraries folder in this zip file. Try that and see if that fixes your issue.

Happy new year to you also.

@dbemowsk Thanks for the reply. After a fresh install of the Arduino IDE and adding the MySensors lib and the DHT lib you send me in the link, the compiling finished without errors but Now I have another strange behaviour where I work already on the whole day but I cannot find it. Looking on the serial monitor I see, (and I include a log from another already working switch)

This "!TSM:FPAR:FAIL" I get also in my DHT project. It is strange that a working divice (4 days ago), load the same script again and I get an error. Any ideas in wat direction I have to look? Could it be something in the config file?? I do not know.

@dick great work. I see you're reusing the same id (6) on the new device. Is this done intentionally? Are you sure there is only one node with the same id running?

[Dick]

@mfalkvidd You are right. This was the problem. I forgot to check that. thanks for the Direction!

[mfalkvidd]

@dick great. Thanks for reporting back.
