Light too 'dim'

[LaborEtArs]

Just installed Tasmota to use it with the Shelly Dimmer 2 Hopefully I got the most recent versions for Tasmota and for the STM32 co-processor The console shows:

For testing I used a 60W standard bulb. When turning the light on (while the dimmer is set to 100%), the bulb is too 'dim'. This optical impression is backed up by the power reading, which shows just 36W (for a 60W bulb). In addition to this, the bulb flickers. Is there something I can do against this behavior? Am I asking the question on the right place, or should I create an issue directly in the Tasmota repository? Many thanks for any help in forward!

Just found, that setting 'DimmerRange 50 200' in the Tasmota console 'solved' the problem. Obviously something with the calibration is faulty. I did not run the original Shelly firmware in front of installing Tasmota. Should I have done so?

Hi @LaborEtArs! I'm glad you managed to fix your issue. Did you also change the Ledtable 0 option to disable the Gamma correction like it describes on the Tasmota Device Repository?

Jep, I followed exactly these instructions :-) They led me to the 'DimmerRange' experiment, which was finally successful!
