Hello people of Lemmy,
I have a light bar for my monitor and it has a remote that (I assume) uses a 2.4 GHz radio. Do you have any recommendations for a Thread-enabled transmitter so I can control it from HASS?
Can you share photos of the underside of the remote and/or light where it lists either “FCC ID” or “Contains FCC ID”? I can’t find a listing on it anywhere to figure out what it does, and a LOT of those labels for radio frequency in Amazon images are straight up lies. There’s so much noise on those drop-shipped items.
I can’t find anything. I might have the manual or box somewhere.
What makes you think a remote uses 2.4ghz? And why would a thread enabled radio help with that?
Most remotes are either IR or 433mhz. Both have multiple options for controlling from Home Assistant.
Can you post a listing for the device you’re trying to control?
The Amazon listing shows 2.4GHz in the last image
It most likely uses regular old infrared
Try to use the remote from the other side of the door and it probably won’t work.
I’m completely sure it uses 2.4GHz.
Here’s someone reverse-engineering the device: https://github.com/Lexy1972/Reverse-Engineer-a-Quntis-Monitor-LED-Bar-Controller
I’d say an ESP32-C6 with an NRF24L01 and some custom code would probably work as a bridge. The ESP32-C6 (and H2) can do Thread. And the NRF24 blast out 2.4GHz signals. I have no clue how Tread and Matter work, though. If it’s HASS, it’s probably easier to skip all the Thread and Matter stuff and write some ESPHone component and forward it over Wifi. Basically an RF bridge. But seems like it’s a major coding and soldering project.
I’d check that as well. I’ve had remotes which just hid the IR diode behind some plastics, I had assumed they were RF, but that wasn’t the case. Also there’s at least two other ISM Bands, could be 2.4GHz or 433MHz or maybe 868MHz in products meant for Europe. They’re usually required to disclose the frequency in the manual or on the packaging, or on some sticker. I’m not sure. Once that kind of information is missing, use it as an opportunity to double-check it’s not IR.
Any Matter/Thread IR blaster should work with HA. Assuming you already have a Thread radio on your HA.
