With my HPSU compact I got Rotex rocon-g1 gateway, to run it using Rotex Cloud. I don't like that much, so I tried to check what's inside and found Beagle Bone Black with CAN module.

https://www.heizungsdiscount24.de/regelungstechnik/rotex-gateway-rocon-g1-zur-ankopplung-der-steuerung-an-das-internet.html

I got root to the device and found there Debian

I had to install python from sources to get working as python in packages is outdated. I'm not sure what driver use to get it working?

Need your help to get pyHPSU working with can0 in this device.

Try it with the italian translation.... "-l IT". Seems the only file that works.
I added a pull request that fixes this an some other errors....but there is nobody to accept his request.

Guys I copied content from rotex-g1 device https://github.com/peak-load/rocon-g1 I see there bunch of outdated and vulnerable nodejs modules and debian packages.

Rotex-g1 is running code from that directory, so maybe will be useful for someone to check how Rotex guys dealing with can bus (commands and codes are there in source codes).

@svde It's beaglebone black inside, with root user. I started from microsd card mounted disk, chroot-ed and then passwd root did all the magic. Btw, Rotex guys recklessly allowed root access for everyone over ssh thinking that only they know root password.

My rotex-g1 mmc disk copy (download, xz, then mount under Linux system, it's ext4 fs is there:

https://mega.nz/#!UBAF0JyR

Decryption key: !YV_zFloYonvcGYt0V_EaUBIamqQ-6EsLfAkeRVB1xgs

It was not easy at start , but was very trivial when it'd done! I give credits to #beaglebone guys at irc.freenode.net

Short instructions

  1. Download Debian 9.2 2017-10-10 4GB SD IoT image image from http://beagleboard.org/latest-images and dd to microsd card.
    https://debian.beagleboard.org/images/bone-debian-9.2-iot-armhf-2017-10-10-4gb.img.xz

  2. Put sd card into beaglebond slot and restart it, you will be booted into debian with default login and password

  3. Mount mmc disk, chroot, passwd

Hi,
I'm thinking of purchasing the Rotex Gateway RoCon G1 for my HPSU compact system.
Do you guys recomend it?

The main purpose is to be able to control (turn off/on) the DHW pump via Homekit/Homebridge.

Thanks for your feedback

migabc commented Jan 10, 2019

Yes, I'm aware of that.
But given that it allows web access (https://www.rotex-control.com/) it should be possible to write a plugin for homebridge.

Anyway, do you recommend this gateway?
What exactly will I be able to control with it?
Do you know if Rotex provides some sort of demo account so I can see what features/controls are available?

You can only control it from the app. Not from the rotex-control.com website. The website only allows you to see some values from the heat pump, but not change anything. I only use the app to switch from standby to automatic1 when I return from vacation. The pyHPSU software can do the same thing.

Thanks for your feedback
Are you also using the pyHPSU software. What can you control with it?

Look at the commands_hpsu_*.csv-files.
There you can the which commands pyHPSU supports.
More commands are supported by the fork https://github.com/Spanni26/pyHPSU spports more commands.

I just found out that my heat pump (HPSU compact 516) does not have the Rcon module . so we cannot connect the Rcon gateway to it
Instead it has XR1P circuit board with connection terminal bar at the bottom (X1).
I'm currently controlling my heating (on/off) by remotley shunting the terminals RTN and RTH on that X1 module.
Does anybody here know the corresponding terminals for turning On/Off the DHW?

svde commented Jan 21, 2019

Do you have a link to the manual of your heatpump? According to the manual I've downloaded of the 516 you should have a RoCon-BM1 board in it. That board contains a canbus connector where the RoCon-G1 is connected to, or a canbus device (like a usbtin) so you can use the pyHPSU software.

It's simple.

get ssh access to device. then change source code for authentication && to || (user and password) to (user or password),
login with username admin and use any password. then You can set your password and return code back :)
