Hello, I have some 433mhz Wall switch and Relais dimmable (Chacon DIO). I can record the 433mhz frequence Wall double switch with DIO WallSwitch double 54502. I can associate this switch with other light in Homey so when i activate the wallSwitch double the light switch on. But in can not from the Homey box activate the 433mhz relay How can i send back the 433Mhz frequence to acivate the 433mhz relay? Thanks for your Help ---

Hello Dijker I have Homey pro 2023 And yes I use DIO APP to record the 433mhz code from the Wallswitch Double. I try to use also the remote control DIO 1.0 but nothing work ---

The relay receives a signal from an existing device and sends it again. To no need to pair the relay with Homey. ---

Does it work without the relay? if you place everything in a short range where the relay isn’t needed? ---

I only record the frequence of the Wall double switch. yes the Wallswitch is direcly paired to the relay and work perfectly. and the Homey recevive also the frequence 433mhz? but how to send this 433mhz frequences? I do not see how to do it. ---

Just click on the tile of the wall socket. PS: recording a RF 433 Signal in Homey is something else as pairing a device. I presume you mean pairing? While paring a RF 43 device like a wall socket, you eighter learn the wall socket a new signal from Homey or you can learn Homey to use an existing code from a remote control. ---

Hello Rmb, Yes I mean Pairing. but after i try do do a Flow but how to do it that the homey send the 433mhz frequence to switch the relay? It look that it only work in one way. Wallswitch send to Homey and relay but not Homey send to Relay. ---

I try also with The developer Tools. The RF Signal and record the Signal 433mhz and try To Emulate. But nothing Happen. ---

Ok, you have a wall switch, not a wall socket. And you have a lamp you can switch on with an RF 433 signal If you have ever paired the wall switch and the lamp directly, remove this connection. 1. Pair the wall switch to Homey 2. Pair the lamp to Homey 3. Make flow a like ```auto WHEN wall switch is switched on THEN switch on light ``` 1. Set the relay in learning mode 2. Switch on the lamp with the wall switch or with the lamp tile in the Homey app. ---

Thanks Rmb So you means it is not possible to juste send the same frequence and canal that my Wallswitch? Because i have the Vera Edge Domotic box and i juste record the signal of the wallswitch and resend it and it work. The advantage is that if you have a probleme with the box you can style switch on or OFF the light because the wall switch is derectly pared to the relay light. I have some other relay that is manuel configured on a 433mhz canal. so those one i can not paired i have to send the good 433mhs canal. ---

While pairing the lamp you can select to “learn from remote”, so the same code will be used. ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/8/c/8c1ca193e046efb62086ff9454ca77da734af8ef.jpeg)
