@BKeyport said in MMM-DHT22:

@Jonae Nicely done.

I’ve used MMM-CommandToNotifcation/MMM-ValuesByNotification for mine, with MMM-Temperature prior to that. Nice to have a specific to device module, though. :)

Thanks for apreciations.

@ankonaskiff17 said in MMM-DHT22:

@Jonae Have you by chance done or looked at any sensors that use I2C?

No
