RFLink: Not able to send on/off to certain devices?

I recently bought a few Cleverio On/off switches (self-learning). I can control them using Telldus Live (either direct through the Telldus app or in HA through the integration), and they show up as entities in the RFLink integration, but it seems I can not control them. Does anyone know why?

When I click the on or off button on the Cleverio remote, this is what shows up in the logfile.

However, the entity ‘newkaku_00195400_3’ in HA shows as a dimmer (0-100%) and does not respond to on/off or any changes in dim-%… Anyone knows what can be the issue, and how it can be resolved?

I’ve also tried adding them to my switch.yaml, where I have other 433MHz devices setup and working, but this did not help. (But maybe it needs to be tweaked somehow…?)
