Request : (new) protocol for Intertechno Shutterswitch CMR500

[RenGro]

Hi,

I have a Intertechno shutter CMR-500 as well as remote control ITZ-500. The shutter is working in pilight by using "elro-hc" protocol. But pilight is only able to open and close the shutter completely - not stopping the shutter in the middle of the window...

So I tried to control the shutter by pimatic and available class": "HomeduinoRFShutter" . I tried all switching protocols but without success :-(

This problem is equal to an earlier issue from "leader21". But the solution for switch4 protocol is not working in my case.

That' s why I used the 'RF receive' command to track the RF signal from remote control. Systemcode A - unitcode 1 --> State on 0101 0101 0101 0101 0101 0101 0101 0101 0101 0110 0110 0110 02 Systemcode A - unitcode 2 --> State on 0101 0101 0101 0101 0110 0101 0101 0101 0101 0110 0110 0110 02 Systemcode A - unitcode 3 --> State on 0101 0101 0101 0101 0101 0110 0101 0101 0101 0110 0110 0110 02 Systemcode A - unitcode4 --> State on 0101 0101 0101 0101 0110 0110 0101 0101 0101 0110 0110 0110 02 Systemcode A - unitcode 16 --> State on 0101 0101 0101 0101 0110 0110 0110 0110 0101 0110 0110 0110 02 Systemcode B - unitcode 1 --> State on 0110 0101 0101 0101 0101 0101 0101 0101 0101 0110 0110 0110 02 Systemcode B - unitcode 2 --> State off 0110 0101 0101 0101 0110 0101 0101 0101 0101 0110 0110 0101 02

The schema seems to be as follow pulseCount: 50 systemcode: 0-3 unicode: 4-7 ?: 8 --> fix 0101 ?: 9 --> fix 0110 ?:10 --> fix 0110 state: 11

When we use '0' as "0101" and '1' / 'F' as '0110', so we can use the following overview for system- and unit codes http://www.fhemwiki.de/wiki/Intertechno_Code_Berechnung

According to this schema I'm able to generate each sequence for systemcode and unitcode manually and control the shutter by the 'RF send' on command line, e.g. RF send 4 3 376 1074 9964 0 0 0 0 0 1100101010101010110010101010101010101100110010102

Could you please support me for choosing the right (available) protocol or could you please implement a new suitable protocol?

Thanks in advance!

Hi RenGro! My intertechno shutter devices are working very well with pimatic-homeduino. I don't think that Intertechno has several RF protocols for their devices. Have you set your turnwheel codes like at the table shown here ? The pimatic codes differ from the pilight ones. https://github.com/pimatic/pimatic/issues/380

my cmr500 device for the Code A 11 looks like that :

    {
      "id": "beamer-leinwand",
      "name": "Beamer Leinwand",
      "class": "HomeduinoRFShutter",
      "protocols": [
        {
          "name": "switch4",
          "options": {
            "unit": 31,
            "id": 10
          }
        }
      ]
    },

Never had any issues.

Hi leader21,

thanks a lot for your quick answer and the link to correct codes

Now it is working :-)

We can close the issue. René
