New to here, we have a power outlet in our roof cavity that is on with no switch and it powers a 24v transformer for our heated towel rail. I am wondering if anyone has had success with using a plug in smart plug to control. I see the temp limit is 50 degrees on most. In regional Victoria Australia so can get warm and wondering if it will work or not. Any thoughts greatly appreciated.
FWIW, I had a similar problem with a cooker hood light. I couldn’t get to the power line to the transformer (which would have been a better option), but second best was to fit one of these. I have the 7-32v bundle with shell. It copes with a wide range of voltages either AC or DC - so should work with your 24v feed. It interfaces with Homey via WiFi and Tuya. Connection to Homey has been very reliable since I installed it 5 months ago - we use it several times a day operated by a presence sensor connected to Homey - response times are good.
If you’re opposed to using Tuya’s servers it has a 433Mhz option, but that’s no guarantee it will interface to Homey (and it’s not something I wanted to get involved with). I guess that, because the device exists, there might be similar devices with alternate connection possibilities out there. I looked, but couldn’t find one at the time.
