Hello,
I asked the support if/when they intended to add an x10 app to Homey and the answer was “you are the first one to ask for this app”.
So if you are concerned and wish an X10 app, please ask the support for it, so I won’t feel so lonely there 
Cheers
John
Hi John,
I’ve absolut no clue what X10 is, but:
Just as additional info.
The current X10 app is indeed deprecated and doesn’t work on Homey pro 2023.
I (and many others) have already contacted the developper who doesn’t seem to be inclined to update it.
(fwi X10 is a prehistoric 433Mhz protocol used more than 20y ago and my 20+ devices are still works fine)
I am also still using a lot of X10 devices (dont fix what aint broken).
And hoping for the app to be updated.
I am still migrating to homey 2023 and using homesh to connect my homey 2019 to the 2023 homey.
That way I can get the “X10” devices connected to homey 2023 (virual devices)
Not sure if @nattelip is planning to convert or willing to hand over the app
Same for me… I have found 2 apps listing X10 appliances on my Homey Pro 2019.
Rfxcom.2 and X10.2
I set both of them as on/off switches on the same channel + unit as the actually working Chacon Dio wst-8500 remote which is still controlling two YCR-3500 plugs neatly. Strangely none of those apps are actually syncing with the switch & plugs….
I also tested the Sonoff app and it’s generic RF button which look to set up properly but gave no result.
Can you lead me on how you did succeed using homeysh… I didn’t came across that lead yet. 
On my homey pro 2018 I have this flow.
(Ignore the doublecheck part, the X10 sensor is sending the signal twice. The doublecheck prevents triggerig the flow twice.
On my homey 2023 this one
I have defined a virtual device that acts like a motion sensor. That device is now in sync with the other homey.
