Hi, I had 2 Eltako dimmers in my livingroom, these where working ok but I wanted to expand my wireless so I purchased 2 pieces Shelly Dimmer 2. I just want to share how I did it.... I have currently no issues.
My first trial to set it up failed - dimmer got overheated, a lot of blinking, interference with other led lamps who also started to blink and so on.
So, I decided to restart and this time everything works flawless. So, in short - what did I do:
1) connected Shelly Dimmer 2 stand alone on power
2) changed IP to static ( outside DHCP)
3) after connecting to my home network, update firmware to the BETA version.
4) made a temporary setup with the Shelly dimmer 2 + impuls switch + connected outlet of dimmer to my living room lamp (orginal feed kabel disconnected). In this way I had a stand alone system.
5) power on on system - via web interface (not the app) connected to dimmer to change settings.
6) changed to trailing + did calibration via web interface.
7) when calibration was completed, powered of the system and powered on again.
8. still via web interface checked the system, all was working flawless - no blinking - no sound and I could use the full range of dimming.
9) tested now via the app and also here no issue.
10) installed all in the wall and powered on the system - all ok.
11) did the same for second dimmer and as expected all ok.
I must say, I always configure and test my Shelly devices via web interface as it seems functioning better for setting up your device then via app ( in my case)
Just wanted to share my findings as I see that many have issue with blinking and sound.
PS: my lamps are from WOFI: https://www.wofi.de/innenleuchten/…e-hampton-12flg
PS2: when I installed my Eltako some years ago, I had also issues with blinking.... I found out that in my switchboard the fase was switched with the zero, so I asssumed I was dimming on the fase After is switched the cables in the switchboard all blinking was gone.
Great board here... tomorrow my other stuff to be installed, Shelly EM, Shelly 1PM and more.
Greetings, J.
