I installed the developer version of ESPeasy 2.0 dev 12 to get my MH-Z19B to work. Unfortunately I can't get it to work Maybe someone can help me.
Platform is Wemos D1 mini.
I tried many PIN setups - I double-checked.
I alway get the following output:
Code: Select all
54264 : MHZ19: Unknown response: 0 0 0 0 0 0 0 0 0 64403 : MHZ19: Error, timeout while trying to read 64404 : MHZ19: Unknown response: 0 0 0 0 0 0 0 0 0
I can't figure out what leads to the situation.
I saw that there are two different versions of the sensor available. Please the picture ((c) Wolfram55: tweakers.net):
I've got the sensor at the bottom.
Here is another picture:
Has someone an idea?
