Hi, There is something strange on Dimmer Items connected to a channel, which has a specific “Absolute Minimum” and “Absolute Maximum”. I created a channel to a MQTT State/Command Topic to be able to change the brightness of a tuya light. The “Absolute Minimum”, which the light supports is “10” and…

The default behaviour is strange, but you don’t need to define a new widget - just set the State Description metadata of your Item: you’ll find min and max settings which you can set to 0 and 100 respectively. I make this adjustment at the end of this tutorial .

mind the rules and don’t post everything vaguely related to the RC discussion post. Only stuff of general interest and specific to RC.

Ok. Sorry. It’s not easy for me to know if this is a RC specific issue or a general issue, since I don’t have this tuya configuration on OH2.5 running and testing and using OH since 2 weeks. if I find issues in future, I will open a new topic.

You shoudl check the widget options. There are a lot. I had asimilar problem with color temperature and brigthness on a zigbee2mqtt. I solved it using a smal java script that covert values

I am a little bit confused. maybe I completely missunderstand the feature, but in my opinion, there is already a transformation enabled by default. The “Absolute Minimum” is “10” and the “Absolute Maximum” is “1000”). If I move the slider to 100, it sends the value 1000 to MQTT If I move the slid…

Hi. I could solve my issue by defining a Widget. Thanks @Dibbler42 . But why is it necessary to define a widget? The values are converted by default without any special setting. minValue = 10 maxValue = 1000 Here the values the slider sends to the queue: Slider-Value → Value in Queue 0 → 10 1…

@hafniumzinc Good point. Thanks. That works for me and is a much better solution than creating a widget.

I’d like to pick this up as I cannot believe that changing the state representation metadata for every single “Dimmer” Item defined by MQTT is the recommended solution… Defining a channel of type dimmer with min/max/step definition leads to an automatic calculation of a percentage value (ref. https…

Perhaps it is a feature enhancement request. Open a GitHub iissue. OH3 development is still very young.
