ESP32 C3 Supermini Randomly switches on (ghost switching)

[OrYaYo]

PROBLEM DESCRIPTION

ESP32 C3 Supermini with MOSFET module (PWM) swithces on randomly several times a daty (around 4-5 times). I have a rotary enconder KY040 connected, with a pull down resistor - 10k - used for the SW (press button). The KY040 seem to have pull down resistors in the module already for the OutputA and OutputB pins, so I just added a pull down resistor to the SW pin. This is another case of Ghost switching but cannot make why, even adding pull-down resistors to the SW channel on the rotary encoder.

The light keeps switching on. Using the latest development pre-built binary.

• Set weblog to 4 and then, when you experience your issue, provide the output of the Console log:

13:09:39.386 WIF: Checking connection...
13:09:43.396 SRC: Light
13:09:43.481 MQT: stat/tasmota_FB3B78/RESULT = {"POWER":"ON","Dimmer":100}
13:09:46.247 CFG: Saved, Count 860, Bytes 4096
13:09:59.397 WIF: Checking connection...

TO REPRODUCE

Wait a couple of hours, the light will switch on automatically (ghost switching)

EXPECTED BEHAVIOUR

No ghost switching :)

SCREENSHOTS

ADDITIONAL CONTEXT

I don't understand what the SRC: Light means. If noisy SW line from KY040 encoder, then you should have a different source. Maybe this is related to the pinout used for the encoder on the ESP32?

(Please, remember to close the issue when the problem has been addressed)

You probably need to fix your wiring.
