      Hi,
      I'm running RRF 3.4rc1 on a Duet 2 Maestro and am considering connecting a DHT22 sensor for monitoring the enclosure environment. The documentation does not explicitly mention the Maestro board, only "Duet 2".

      • Is the Maestro capable of handling the DHT22?

      • If yes, which connectors can be used? E0, E1, X, Y, Z-stop? Only the temp daughterboard connector (CS1/CS2)?

      /Ö

        Answering my own questions after some experimenting. The Maestro handles the DHT22 fine when connected to the CS1 or CS2 pin (as documented for Duet 2).

        For the record: the AM2320 Temp/Humid sensor (not AM2302) also works fine, when connected using its "single bus communication" mode, which seems to be backwards compatible with DHT22/AM2302.
