LCN light switch on Doesn’t work, only switch off

Configuration
1

Hi, maybe someone here can help me:

I have HA running via an LCN-Visu (as well as Domiq, openHAB on Visu also works) and LCN is from about 2009. The connection to HA also works. After I have set up a simple light switch as an entity / module output, the ON/OFF status is also displayed correctly in HA when I switch directly on the switch. I can also switch the light off via HA, but not switch it on via HA. The light is also dimmable, I have tried different constellations / entities, but it does not work. If I enter entity dimmable, 100% light is only ever displayed as 25% and can be switched off but not switched on. Any idea what I can try? Thanks in advance!

Hi @ca1000,

you need to change the dimming steps. Old modules only support 50 steps. I guess you configured your system having 200 steps.

Go to Settings → Devices & Services → LCN. Click on the three vertical dots on the right side of your integration entry and select „Reconfigure“. In the dialog click on „STEPS50“ and confirm with Ok.
