Using Homematic IP 6 Button Wall-mount Remote Control Unit (HmIP-WRC6) in Homeassistant

Configuration
1

So, I had this strange thing, that I didn’t get any events from Homematic in my Homeassistant from a newly connected HmIP-WRC6 remote control unit. But why I bought it, was to control my Yeelight with Homeassistant.

Just to clear things up: I have a RaspberryMatic on a RaspberryPi3 (Homeatic CCU3).

After some research, I found out, that it seems to be, because the IP Products of Homematic does have a encrypted connection, there is no possible way to get any events out of this remote WITHOUT a direct- or program connection inside the CCU.

What I did to use this successfully in Homeassistant was, that I used the first channel (named it “WRC6-Workaround”) of the virtual adapter (HmIP-RCV-50) and connected all 6 buttons of that HmIP-WRC6 to this channel. Finished. After this, you get every button (short/long) press correctly in Homeassistant (not the HmIP-RCV-50 Events!).

The virtual HmIP-RCV-50 looks like this: chrome_WjlqaIIEFT

And the Program Connection looks like this: chrome_cSBoeaotg0

I hope this helps someone.

Thanks for mentioning it. The documentation contains a similar approach to address the same issue: homematic.keypress events for HomeMatic IP devices

Hi Daniel,

weeks ago I found one of your posts regarding Homematic remote controls in HA
using custom_homematic integration.
unfortunately I can’t find it anymore.

It was about creating an automation with a HM button press as trigger, which I couldn’t find in your github documentation. I’m already using it successfuly in a regular ha automation, but I got stuck using it in (ha) node-red. I’d like to see it again to find out that there was further helpful information.

Could you be so kind to send me a link please ?

Regards

That topic has been discussed numerous times, so I don’t know which thread you’re talking about. But you can look at my activity here and find it that way: Profile - danielperna84 - Home Assistant Community

@mdo Did you manage to get it working?

I am using a Homematic IP CCU 3 and have a HmIP-WRC6 Wall Switch with 6 Buttons.

The switch used to control some Philips Hue Lights. I am now in the process of moving the programms from Homematic IP to Homeassistant.

I created the automations on HA yesterday and deactivated the old programs on Homematic CCU. First, everything was working, my Philips Hue Lights where correctly being turned on and off.

Then I deleted the programs on Homematic CCU and suddendly the Switch stopped working (No events received anymore in HA). That kinda sounds like the problem described here: Homematic - Home Assistant

BUT: I am already using the custom integration GitHub - SukramJ/custom_homematic: Custom Home Assistant Component for HomeMatic

For anyone finding this thread. I managed make it working by just adding a programm in homematic IP, which triggers the light when clicking on the switch:

So basically the same, what I also do in Home Assistant.

The programm in homematic IP can be deactivated, it seems that it’s enough that it just exists.

Having that programm, the events of the switch arrive correctly in Home Assistant.

RTMF is always a valid option.
