I’ve a Dimplex Opti-Myst fire installed at the house. Essentially, this is an electric heater with a water-vapour flame effect. The flame effect can be operated separately from the heater and uses a wireless remote control.
I want to see if I can wireless sniff out the control code to activate the flame and active it from HA within my automations…
I’ve taken apart the remote control to look for any kind of symbol to suggest how the remote communicates but there’s not a thing on there! I was thinking if it is RF to sniff out and repeat the signal from a Pi add on, somehow tied to HA.
Has anyone else done anything similar to this, or would anyone know how I can determine how the remote communicates with the fire. There’s next to no technical docs available on line. So I’m a bit stuck!
Well, if there is a diode, that would be IR, if not it’s RF.
Now, if it’s RF, it could be on 433MHz (most common) or 868MHz. Maybe look for those numbers on the board, or maybe post pictures of the board for those more familiar with the matter.
Note that, anyway, you would need hardware to emulate the remote, being IR or RF.
Just an “addon” won’t magically enable that.
No further with this I’m afraid. I’m thinking the other solution might be to wire in a Shelly wifi relay to switch on/off the flame effect. I’m not sure if they have a device that switches low voltage though… I need to do some testing but this is still something I’d like to do!
