So - an update for anyone who comes across this topic subsequent to this.
The Telis 4 remote is using an extended version of the RTS protocol which is a) encrypted and b) patented so can’t be controlled using the RFXTRX433e. Hence how it is able to do small gradual movements that the RFXTRX cannot.
It also seems it is NOT possible to change the mode of the T+L25 to be EU rather than US which might have resolved it.
So instead I’ve looked at my use case and approached it differently.
Primarily what I wanted to do was a) open the tilt on the blinds to half way in the morning and b) close it at night. Also put that on an Alexa control. I also wanted to be able to control the blinds to full open and full close if required.
So here’s what I’ve done.
I’ve adjusted the blind so the ‘my’ position is down with the tilt at half way. E.g. my default ‘open’ position.
I’ve created a new switch item called ‘blind’. And I’ve added an item to the rfy actuator against the ‘shutter’ channel.
I’ve added a rule which captures on and sends the ‘stop’ command (also known as ‘my’ in Somfy language) to the shutter channel item. I’ve added a second rule which captures off and sends the down command to the shutter channel item.
I’ve then installed the hue emulation and added the ‘switchable’ tag to the blind item.
That has resulted in being able to say to Alexa “Open the blind” and have it tilt and then “close the blind” shutting it.
I’m thinking to fulfil my second criteria - I will add a second switchable item called ‘blind full’ which traps the on command and sends ‘up’ and similarly ‘down’ for the off command. That will result in ‘Alexa Open the Blind Full’ being raising it up high.
Not perfect - but pretty good.
