I tested the sensor with an "arduino nano" and it works correctly.

I had a typo on pin of the sensor try to use the pin D0 that I had already used but I use D2 however I have the same output in the log ,. I used AUTO_DETECT and detects a DHT22 this is correct and now I try specifying the DHT22 model and I get the same result on the log

I use a resistor pullup on data pin, I dont know what else to do, please help

That's a problem that i'm also having, but i think it's something related to the sensor or the board.
On one of my boards i manualy change from AUTO_DETECT to DHT11 and the problem was solved, on the other one it did not.
I'm gonna change the sensor to see the output, but in my case i thing is samething related to board since everytime i turn on the relay this errors are constant.

@carlosmgr

I just spend the last hour testing, i changed every thing except the board, and when i turn on the light the DHT11 gives me the checksum error. The intriguing part is that if i disconnect the light cable and leave the relay on, i get no errors....

@mefizto what board are you using and why are you using input?
Are you using the dht sensor with a transistor between the vcc and data?

The "Falling edge for bit -1 failed!" errors it's when do not have anything connected.

This feels like a hardware issue rather than a software issue. Perhaps this is not the correct forum to continue this discussion. However that is up to the package maintainer. :)

If the maintainer feels that continuing the discussion here is productive, more details on the hardware setup are necessary. Board model, DHT sensor model, circuit diagram/picture, etc.

works fine for me with that code and AM2302

sensor:
  - platform: dht
    pin: GPIO1
    temperature:
      name: "Living room temperature"
    humidity:
      name: "Living room humidity"
    model: AM2302
    update_interval: 15s```

possibly your problem is here

sensor:
  - platform: dht
    pin: 
        number: D7
        mode: INPUT

@carlosmgr im just trying to get it to work, sometimes it does and then not anymore, i guees i will try a diferent board, i use AUTO_DETECT and it recognise DHT11 or DHT22 according to the case, but still get the "Falling edge for bit -1 failed!" errors also when i specified the model

So I don't really know how to help with your problem @mefizto unfortunately, from what I see it kind of looks like a hardware issue to me. Maybe you can share your wiring?

A bit of clarification:

  • The way AUTO_DETECT works is that on the first measurement, esphomelib basically just tries to get the data as if it was a DHT22. If it doesn't work in DHT22 mode, esphomelib just assumes it would be an DHT11.
  • Falling edge for bit -1 failed! means that the DHT doesn't respond to the measurement request. To tell the DHT to start a measurement, esphomelib first pulls down the data line to ground for a certain time and then waits for the sensor to start sending data. If the sensor never responds, that error appears.
pin: 
   number: D7
   mode: INPUT

The pin shouldn't be declared as an input, just a simple pin: D7 should work. Declaring it as an input should however just mess up the very first measurement if I'm correct.

I made a post about this and the DHT22. I had to hook my ground from the sensor to another pin like D0 and add that pin as a switch. My DHT22's work everytime now.

Closing this issue as I think the DHT integration has gotten better now. At least I've not seen these errors pop up in a while on github.
