Hi @laf Would you mind detailing how you calculate the device ID?
I have a bunch of LightwaveRF stuff, and all the codes are ‘learnt’ from the remotes that I have lying in a box now. I tried making up codes myself, but I think there’s a checksum at the end that I’m missing out on. Would be great to dispense with this spreadsheet of codes from all the remotes!
Any thoughts? 
I just made mine up as I didn’t have many but you can use:
Let me know how you get on with it.
That’s fantastic! Thank you 
Not only does it allow me to get rid of my LightwaveRF codes spreadsheet, but it turns out that I can create codes for other kit too, like the Energenie 4 gang that’s been sitting idle for a year - allows for Classic Energenie support via 433MHz to be closed off 
How do you edit/change a device from a ‘switch’ into a light dimmer?
Another user moving from Domoticz over to HA and have existing LightwaveRF light switch dimmers, wall sockets and PIR sensors.
I’m using an RFXcom device, in auto update it finds 3 x temp sensors which I’ve added (not lightwaveRF).
It finds the Lightwave PIRs
It finds my doorbell but I don’t seem to be able to get it to acknowledge it being pressed
I can’t find my Dimmer light switches but manually added the event code at which point I can turn the dimmer off/on but how do I dim it?
They appear as a ‘switch’, I’ve seen other threads where you edit yaml files but I can’t find any reference to RFX or the device in any yaml file, I can’t see anywhere in the device or under the integration to change it.
What do I change where to get them to dim etc?
Think I might of cracked it in the last 5 minutes, found this Rfxtrx lights are recognized as switches in 0.113 - Configuration - Home Assistant Community (home-assistant.io) talking about a bug and there’s a reference to having 10 0F70 as the last 6 entries, changed my code to use this, re learnt it and now appears as a dimmable light switch, boom!
