Domoticz

I have devices like shutters etc. and can control them with my RFXCOM transceiver on 433MHz.
Now I also own devices which communicate on 2.4GHz with a remote controller. See photo (Klarstein IR panel, LED lamps).
I can't figure it out if there is an 2.4GHz USB device like the RFXtrx433E to scan and replicate the remote control signal.
Did a lot of google and a lot about 2.4GHz Wifi but can't be used.
Does such device exists or is it impossible?

No body? Maybe I have to ask this question in another tread?

In comparison to 433Mhz (also 868Mhz) for 2.4Ghz there no generic devices (at least of which I know off) that support many different, mostly proprietary, protocols used by hardware vendors.

In the past many vendors used 433 (and later 868) product/vendor specific protocols.

Nowadays, most devices use a more standardized protocol like Z-Wave, ZigBee (soon also Thread) which are often on either 868Mhz or 2.4Ghz.

And a lot of ‘cheaper’ devices use 2.4Ghz Wifi, but Wifi is generally not considered as a good choice for ‘IoT’ devices.

You could build something on your own if you are up to the challenge.

My suggestion would be to replace your devices for devices that use more common standards.

Thanks for answering.
So there are no devices to capture (snif the air) the 2.4GHz remote control signals and replicate?
Like IR there are remote controls which can 'learn' and replay signals.

You mention: 'You could build something on your own if you are up to the challenge.'
So this could this be done? Do you mean with eg Arduino?

(Just to be sure, I do not mean devices that work via WiFi, but purely with a 2.4MHz remote control.)

Not something like RTX433 or an RTL-SDR or similar as far as I know.

And yes, you can probably build something with Arduino/wemos, etc.

Maybe better to use an esp8266 or esp32. Problem might be that they have a wifi oriented stack while you might need to create a custom stack.

So maybe use something like a nRF24L01p module connected to a controller like Arduino (or wemos/esp32/etc) as you need a second communication layer (wired or wireless) to connect to Domoticz.

Technically this should be doable but I don’t think it is easy if you are not an established thinkerer.

Hi all.

tne7laa, you keep mentioning 2.4MHz, whereas your picture shows 2.4GHz, and other posters also talk about 2.4GHz.
Maybe, for clarity purposes, you could confirm and correct the title of the topic.

I'm very sorry! You are correct. My mistake. 2.4MHz should be 2.4GHz of course. Hope all did notice it and did knew what.
I have changed it in my post where I could.
Also I think it does not change the answer I think. Does it?

Of course not

I use rflink to control my 2.4GHz MiLight devices.
I'm not sure whether it can be used for your devices.

Thanks for you answer! I will look into it. Looks promising.
Will need an Arduino Mega and RFLink Gateway board. Don't understand why an Arduino because Raspberry Pi has also programmable I/O.
Il will ask and come back to let ik know.
