Hi,
I have installed a Shelly Dimmer 2 with 3 dimmable Philips bulbs 3.4W, attached. The lamps are exactly same.
I experience frequent and random flickering, with all the calibration methods I tried (with and w/o By-pass option set, with and w/o auto load detection set).
The Shelly has been installed on the wall without N, so I use a by pass module on the lights. I saw other threads having similar problem with N present, so I thought this is different problem to report separately.
I have also tried the antiflickering debounce option with a few values (80, 100, 150), it didn't help.
Flickering does not happen when dimmer is set at < 30%
When I disconnect any two of the three lamps, calibrate and operate with one lamp (any of the three) the operation has no flickering, it's perfect. I also tried to connect a second and the third lamp using the calibration created with one, but it didn't help. After connecting the second, flickering starts.
Any ideas what is the problem and how to solve? Why more than 1 lamp connected creates the problem?
The firmware of Shelly Dimmer 2 is 20211109-131033/v1.11.7-g682a0db.
