I have a hardware setup consisting of a Waveshare DALI2 Expansion Module https://www.waveshare.com/pico-dali2.htm and an ESP32-C6-Pico https://www.waveshare.com/ESP32-C6-Pico.htm. I am flashing it via the Tasmota WebInstaller, selecting the 'Tasmota (English)' version. I am now running the DaliScan command.

I hope you've read the docs at https://tasmota.github.io/docs/DALI/ where it states you'll need to remove the connection between pin 4 from the esp32-c6 to the pico dali2. Easiest way is to remove or cut the pin from the ESP32C6 header

If you did, then enable more logging with command weblog 4 or seriallog 4 and see what happens. It should look like this:

Thanks for the reply. I removed the 4th pin as instructed and ran the command in сonsolу weblog 4.

The DaliSacan command needs options as can be read in the docs:

  // DaliScan 1     - Reset and commission short addresses
  // DaliScan 2     - Commission unassigned short addresses
  // DaliScan x,5   - Commission up to 5 short addresses

But considering the TX collisions I expect you didn't set up your DALI network as it should.

Are you talking about the power supply and driver combination from the DALI2 expansion Module? They're connected and there's 17 volts on the DALI bus. But when I connect the ascelograph, I get a direct 17-volt line.

although one driver is connected
if I run the command DaliSend 255 5 the lamp turns on
I couldn't figure out the error with the ESP32-C6-Pico module - Tx collision
I noticed that when using the ESP32-S3 ETH Camera Development Board on the DALI2 expansion Module, the LED with the inscription DALI lights up, but when connecting the ESP32-C6-Pico, this LED does not light up.
