[workaround] Somfy cover with RFXtrx not working

Configuration
1

Hi,
as per RFXCOM RFXtrx - Home Assistant I programmed my Somfy to work with RFXmngr.

ID: 5 55 55
Unit Code: 2

RFXtrx works fine in HA as I get some t° data from the neighbours.
That’s what I get in the logs when I hit the [stop] button which should put the shutter to preset position. But UP/Down do’nt work neither:

2017-09-08 17:35:04 INFO (MainThread) [homeassistant.core] Bus:Handling <Event call_service[L]: domain=cover, service=stop_cover, service_data=entity_id=cover.stores_electriques, service_call_id=1960908880-17>

2017-09-08 17:35:04 INFO (MainThread) [homeassistant.core] Bus:Handling <Event service_executed[L]: service_call_id=1960908880-17>

And this is my config :

cover:
  - platform: rfxtrx
    automatic_add: False
    signal_repetitions: 1
    devices:
      071a000005555502: # RFY
        name: Stores éléctriques

Has someone any idea what could be wrong?
If you have a working setup can you share your settings and logs?

Thanks

seems that my device ID is correct as it doesn’t appear in the devices when I alter it.
Does anyone has an idea how to debug this further?

have you ever found out how this works? according to this thread, your code is missing trailing zeros.

071a0000 0555550 2
09190603 0A0A0AA 1 00 00
09190603 [id] [unit_code] [cmd] 00

resulting in that code, this should work:

cover:
  - platform: rfxtrx
    automatic_add: false
    signal_repetitions: 8
    devices:
      071a0000055555020000:
        name: Stores éléctriques

Hi ,
Thanks for pointing to this, I’ll check, but actually I bought an RFLink set which worked out of the box^^^solder iron and since then my blinds go up and down with the sun’s elevation.
BRB reprogramming the RFXtrx.

having both, a rfxtrx and a rflink is a good solution, that i also chose :slight_smile:

I know this is a very old post but who knows, maybe this might help someone struggling with RFXtrx and Somfy covers.
As my rflink stopped working a couple of weeks ago, I took the time to try to get the RFXtrx device to work with my blinds.
I added the integration again with event code 071a0000020F0F02.

Packettype    = RFY
subtype       = RFY
Sequence nbr  = 13
id1-3         = 020F0F decimal:134927
Unit          = 2
Command       = stop
rfu1          = 00
rfu2          = 00
rfu3          = 00
Signal level  = +10 dBm

That worked and I get a buton for down, stop and up. But still nothing moves from there.
That’s from the HA logs when I push down, stop and up:

That’s what I get form the RFXmngr when I transmit Down, Stop/My, Up:

So the commands sent from HA don’t correspond. So I tried to use the service rfxtrx.send to send those commands

#down
service: rfxtrx.send
data:
  event: "0C 1A 00 12 02 0F 0F 02 03 00 00 00 00"
#stop
service: rfxtrx.send
data:
  event: "0C 1A 00 13 02 0F 0F 02 00 00 00 00 00"
#up
service: rfxtrx.send
data:
  event: "0C 1A 00 14 02 0F 0F 02 01 00 00 00 00"

And this worked. I can know use this for my automations. I don’t have a nice cover panel but that’s a minor problem as I’m happy to get the blinds automated again (and that I can use the RFXtrx module after 5 years of taking dust).
