Multiple Remotes not working

[Trabbi1999]

Hi,

I'm currently trying to realize a CC1101 Multiple Remote Setup via MQTT. Everything is working fine so far, the script does what is should do, BUT it fails at the most important point: sending out the command via the CC1101. The main problem is located in

void sendCC1101Command(Command command)

The only working remote is somfyRemote1. When I send the value 100 via MQTT to the topic home/buero/rolladen the correct shutter is moving upwards. When I send 100 to the other topics defined in the top of the script, everything is working, despite the sending, all Serial.println are displayed correctly and I can confirm that that part is working. I used parts of your example "Multiple Remotes" and modified it for my use case, but its not working.

I tested all shutters seperately with the CC1101 example script with the same Remote codes as defined in my multiple Remote script (I changed them to XXXX for github, thats not the error :P) and its working perfectly fine.

All remotes are configured the same, but only one is working. Do you have any idea why?

Here is the script (unfortunately, the github script function does not work) :

During separate testing, did you also use the correct rollingcodestorage for the different remotes?

PS: I fixed the GitHub code block syntax in your comment by using three ` and a new line

[Trabbi1999]

OMG Danke :D that was the problem. Everything is working now. But, antoher question/issue:

I took over the part with the EEPROM Adresses from your multiple remote skript, as you can see above (0,2,4,6). Unfortuantely, only 0 and 2 are working correctly. With higher values I can program the shutters, but i cannot control them. It's working now with following eepromaddresses:

somfyremote1: 0 somfyremote2: 2 somfyremote3: 0 somfyremote4: 0

As I said, its working with that setup, but will the multiple use of the address 0 cause issues? or shouldn't it be a problem?

Danke :)

If you use the same address for multiple stores, they override each other and cause multiple issues. You can try to reset the EEPROM at that addresses to 0 and reprogram the shutters.
