Somfy Tilt & Lift 25 WireFree RTS

#1 Post by fholding » 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?

There are several reports detailing the behavior you comment on.

It seems clear that the blinds have 2 working modes:
10.2 Using a Telis RTS remote control
By default, the Mod/Var receiver is delivered in “US” mode. When Telis RTS remote
control is being used:
  • Briefly pressing (< 0.5 seconds) on the ˄ or ˅ button of the Telis RTS remote
    control will cause the blind to go up or go down to the end limit.
  • Pressing and holding (> 2 seconds) the ˄ or ˅ button of the Telis RTS remote
    control will cause the slats to tilt.
10.3 “Europe” mode
Using a remote control in “Europe” mode:
  • Briefly pressing (< 0.5 seconds) on the ˄ or ˅ button of the Telis RTS remote
    control will cause the slats to tilt.
  • Pressing and holding (> 2 seconds) the ˄ or ˅ button of the Telis RTS remote
    control will cause the blind to raise or lower to the end limit.
But if I am not mistaken, the RFLink implementation does not support the TILT function of blinds, so it is not possible to control both functions (UP/DOWN & TILT) using RFLink.
Changing the EU/US mode allow you to modify the UP/DOWN behavior in RFLink (discrete/continuous).

I wonder if it will posible to implement in RFLink the TILT function.
Recently RFXCom has implemented this functionality: @fholding, maybe your remote's debug traces can help to see the differences in UP/DOWN and TILT signals: Refs:

A solution is in the works.
Anyone technical with a usb logic analyzer that has this issue?
In any case, we could use someone with the issue being able to debug and test..

I have an oscilloscope but do not have a logic analyzer but hope I can help and test.
What I have is 4 BSO(brise soleil orientable) with 4 paired somfy remote (https://www.somfypro.fr/trouver-un-prod ... ATION_RTS_).
so manually I can control the up, down, tilt, my (wich is a kind of stop) on each BSO.
I mounted an ArduinoMEGA RFLink with various small transceivers 433,92 and 433,42 but was not happy with the result so I bought the nodo 433,42 module and I can now reliably capture the communications between my remote and the bso using RFLINK Loader v1.1
what I can see and do up to now is stuff like that:

as you can quickly see:
the up, down stop are decoded but wrongly as stop
the tilt orders are not decoded at all

I tried also to pair (with same problems as above)
nevertheless I was able to make the thing move up or down but only about 20 cm

My final aim is to integrate in DOMOTICZ but for now I wish first to have a reliable behaviour first in RFLink.
Hope I can help this to make some progress.
Is there somewhere a complete RTS order list with the appropriate syntax ?

I made it work (almost):
with RTSLONGTX on I am now able to pair (does not seem to work without that)
I used 5 RTS Record address (one for each of the four BSO and one to move all simultaneously)
It works thoug I still have the following issues:
1 to move a BSO all the way (up or down) I need to issue the same order 3 times
2 stop means return to position down with 45° opening (I have no way to stop the up down movement when initiated) so this is only one of the function of the MY on the remote (MY stop any movement on the first press and another press will make it move to the down 45 position)
3 no control of the venitian angle

For me the most annoying is the issue 1.
I observed also strange behaviours like the RTS record table is quicly full even if I use only record 0 to 4/ it seems that the manual remote are filling those without reason. Is there something that is pairing stuff without telling us?
Also it takes sometime a very long time to get the answer 20;...OK; this is not an issue but it may be for integration with DOMOTICZ (or other software) if they wait for the OK return.

Ok, great info..
I am looking at the tilt commands as well.

I have the same issue - the up/down command only moves the blind a few cm (slower than when using the remote). I'm using the Nodo 433.420 gateway and HomeAssistant. Don't suppose you've managed to make any progress here, Stuntteam? Let me know if I can help test/debug.

In case useful, I've just discovered that on RFLink32 (https://github.com/schmurtzm/RFLink32-F ... -RF-Bridge) the up/down commands work properly - i.e. send the blind all the way up/down.

I have a similar issue, with the Telis MOD/VAR Type. I have a remote control with an up and down button, to open/close the cover (with a short press) and a wheel to tilt. Sadly it is not possible to change the mode between US and EU mode, to temporary fix the issue.
