After some testing around with the existing klik-aan-klik-uit devices, I got the AWST-6000 device to work with this one. Just a little tip if anyone else hasn’t managed to figure it out - haven’t seen it on any lists myself.
How did you get the MIMST-1703 installed in Homey? I couldn’t find it under Nexa…
EDIT: Sorry - you installed it as a AWST-6000?
