Converting a MAX! Cube to CUL/CUN to use with Home Assistant

swifty · October 25, 2018, 3:45pm

Yes, the wall thermostat should pair OK with homegear.
I have the same unit, but it’s sat in a drawer now, since I just use HA to adjust the setpoints instead.

I’d suspect that the wall thermostat wouldn’t update the radiator valves by default with the new firmware, but you could easily get it working using automations or node red.

ie. when wall thermostat changed, set radiator x, y and z to the wall thermostat value.

I meant update the “current” temp to the sensor value in the wall unit. Can you update the “current” temp of the radiator valve as well as target temp?

I dont know the internals of homegear, but i think that /var/lib/homegear contains data that should be backuped like the paired devices…

For the influxdb i think it is used for node blue, but i dont know it exactly.

So i made a version without influxdb and it seems to work, at least for 22 hours, it also survived a restart of the homegear container.

i will start to move all my MAX!-component to homegear.

You happy of the switch? Did the valves report temperature values (with the HASS Max component most of the time not)

Klagio · October 25, 2018, 6:41pm

I copied the five files in the directory \ubuntu\addons\Homegear when I go to the addon store I do find HOMEGEAR SGR addon, when I click INSTALL, nothing happens.

I run HASSIO on a Ubuntu NUC.

Yes, you are absolutely right. I made a new version of the HassIO HomeGear addon which mounts this folder out. It is installable from a repository. Node-BLUE is included and working great. So I will leave influxdb inside as well.

If you’d like to share your version of the addon, maybe we can merge the best of both in one addon.

swifty · October 25, 2018, 8:11pm

Oh sorry - I misunderstood.

So, I dug the wall stat out of the drawer this evening and paired it with homegear.
Good news - the devices can be linked as per the original MAX functionality, so the wall stat can control multiple radiators, and also reports its value to the radiator valve.

To achieve this, pair the wall stat in homematic manager as per the procedure for the radiator valves.
Then select the ‘Verknupfunger’ tab, and press the ‘+’ button at the bottom.
In the new window under sender, select the serial of your wall stat, then select the valve(s) under ‘Empfanger’ - then press ‘Anlegen’

The devices are now linked

AndrejDelany · October 25, 2018, 8:15pm

Have you verified that other addons install correctly?

I have tested this on a standard HassIO on HassOS install (see https://www.home-assistant.io/hassio/installation/) on a RaspberryPi 3. As this device is ARM based, I’m not quiet sure, if this addon will run on x86 as well.

AndrejDelany · October 25, 2018, 8:19pm

Yes, those “Verknüpfungen” work well. With those, it’s easy to link Thermostat <-> Thermostat, Wallthermostat -> Thermostat and WindowContact -> Thermostat. Has anyone found out, how to link EcoTaster with Termostats?

badgerhome · October 25, 2018, 8:30pm

Thank you for confirming! Very useful information. I now have a big decision to make about whether I keep my Nest setup or ditch it and use the generic thermostat component with a sonoff or similar.

Such a shame the Nest API doesn’t allow read/write of the “current temperature” or it would be perfect.

Klagio · October 25, 2018, 9:38pm

yes all addons works, just this not

Klagio · October 25, 2018, 9:48pm

Adding yours gives this. Sorry I don’t know much about docker

Hi!

In case of a HASSIO installation, where do you find this file?

lubeda · October 26, 2018, 1:36pm

Yes, this addon will not work onx86 because of the Docker Base image

FROM resin/rpi-raspbian:stretch

In the official Add-ons hass.io will try to use the right baseimage by using this in the Dockerfile instead:

ARG BUILD_FROM
FROM $BUILD_FROM

Which did not work in my case

swifty · October 26, 2018, 2:18pm

Would be great to get an x86 build of the addon going since I guess there are a number of people running hassio on VM’s / other tin that are not Rpi.

Anyone up to the challenge ?

I may have a look myself, but free time is lacking recently!

COPIED FROM ANOTHER POST

There is no official add-on but you can create your own easily.

Install samba addon (for ease)
In the addons dir create a new folder “Homegear”
In the Homegear dir create a file “config.json”, and paste this into in and save:

    {
      "name": "Homegear",
      "version": "latest",
      "slug": "homegear",
      "image": "homegear/homegear",
      "description": "Homegear",
      "url": "https://hub.docker.com/r/homegear/homegear/",
      "startup": "before",
      "boot": "auto",
      "ports": {
        "2001/tcp": 2001,
        "2002/tcp": 2002,
        "2003/tcp": 2003
      },
      "environment": {
      },
      "arch": ["amd64"],
      "options": {
      },
      "schema": {
      }
    }

You may need to change arch if on RPi - I am on x86
Save the file, open hassio store and you should see local addon.
Install it and start it…

Works for me at http://hassio.local:2001

Klagio · October 26, 2018, 2:44pm

I followed this guide and the addon seems installed. I do not know how to test it since I didn’t flash trhe MAX Cube yet.

I can click on NODE-BLUE but it asks for a user and password, which I do not know

swifty · October 26, 2018, 3:36pm

Nice find, might check this out when I get the time

AndrejDelany · October 26, 2018, 4:08pm

Does this add on store the data outside the container or does it reset on every rebuild?

Klagio · October 26, 2018, 4:23pm

I have no idea, better ask the creator of the post @hijinx
