Somfy Tilt & Lift 25 WireFree RTS
Posted: 14 Dec 2020, 18:06
Hello,
I've successfully soldered the Somfy version of RFLink Gateway, loaded the latest RFLink firmware into Arduino Mega and successfully connected the Gateway to my HomeAssistant.
The gateway should control Somfy Tilt & Lift 25 WireFree RTS CENTRAL roman blinds, but I have the same problem as this guy, and it is related to the length of signal received by Somfy motor controller:
https://community.home-assistant.io/t/r ... bit/187904
He has finally found the solution, by switching his motor from default US mode where short press of the UP/DOWN button makes the cover go all the way up or down, to the European that works opposite.
Unfortunately Somfy Tilt & Lift 25 WireFree RTS CENTRAL does not support European mode. I have verified this with the Somfy documentation.
The procedure described in Somfy manual for switching between US/EU modes for the motor mentioned in HomeAssistant forum (J406 RTS) is used to change between roman and venetian blinds modes in Tilt & Lift 25 model.
As far as I understand this issue my only way to operate the roman blinds normally is to send a shorter signal from RFLink that would imitate short button press on the remote control.
I have not found any command to shorten the signal transmitted by RFLink.
Any alternative solutions do not work, eg. with RTSLONGTX=ON command is still way too short as my blinds are almost 3meters long and multiplied signal repetitions makes the blinds to roll very slowly (not in full speed) with many stops between commands received.
I'm attaching the graph from RTL-SDR that shows the difference between a signal sent from the Somfy remote control (the small one on the bottom) after which the blinds go all the way up or down and one very strong and long RFLink signal that is causing that blinds move just a little bit for the time of the transaction length - ie. few centimeters and stop just after the transaction ends.
Could you pls help me with this issue?
