Not sure if the correct category, please advise if not correct.
I have a Dimmer (sonoff type device) flashed with Tasmota in OpenHab2. To control the dimmer I send MQTT DIMMER=nn. To read the dimmer I use JSONPATH:$.Dimmer to extract the DIMMER nn from the JSon string. The Openhab thing and Item are defined as a string.
I can’t see a way of using the Homehabit slider control or anything else to mimic this operation.
Is there any way of doing this?
