This is a bug in Homey’s software that should be reported to Athom.

Hi there,

also successfully cloned a 433mhz RF remote with 3 buttons controlling a Projection Screen.No rolling code from what I can know.

**But got the same « EINVAL (2:write) » error while pushing on any of the 3 buttons.**

_→ Is this bug already reported to Athom ? Any update from athom or anyone here?_

Just report it to Athom and you get your answers.

Hi there.

Update:  
Got an answer from Athom.  
It’s a known issue with some cloned devices, without knowing precisely which ones and why they trigger this error.  
I sent more info about my buttons RF codes, and developers have been provided with those. No commitment given on any resolution date.. just waiting with my non-working devices..

I can clone a signal and replay it unlimited times(not rolling) where i name the signal, but when i add the unit and try to start/play it from the panel nothing happens?

Hello

I also successfully cloned a on & off signal from a 433mhz RF BT710 Thermostat (No rolling code from I expected.)

**But got the same « EINVAL (2:write) » error while pushing On or Off button.**

I will also make a call.

Hi Daniël,

Thank you for contacting support.

This signal isn’t supported for cloning. That’s what this error means.

Have a nice day!

Best regards,

Daphne

So, why are error messages often written in encrypted Klingon?”
