I'm fairly new to Node-Red, but not a complete novice. I have successfully created a few automation flows that work quite well.
I just installed a new Sonoff TX 2 channel switch, which I flashed with Tasmota, in our retreat to power a ceiling fan and light. I've been able to add the "switch" definitions in HA's configuration.yalm file and the two switches show up on the HA home page. I can switch on and off the fan and light from HA's home page, so that all works.
What I am trying to do is automatically turn on the ceiling fan whenever the fireplace, which is set up on a generic thermostat climate control, is set to heat mode. I can get a trigger from the climate control, but the problem is, the new fan switch and light switches do not show up in the list of devices to services to call.
I can call other switch services,so I know this should be possible, but they just don't show in the list.
What other info would you like for me to post to help you help me?
