Östberg Heru Control your Östberg Heru ventilation system. [image] Östberg Heru | Homey Air quality is life quality Current version Stable: 1.6.0 Test: Gen 3 with Remote Make sure you system first has modbus enabled from the remote by going to the Service …

If you don’t see the modus settings in your current remote, you’ll have to do that, yes. The Modbus settings should be in the service menu which you can access with the code 1199. In addition you’ll need a tcp to rs485 converter to be able to use the app, which I bought on ebay for around $20.

Hi, I assume you ‘must’ have an external RS485 converter to use this app? I have the new HERU 160 T EC, which supports Modbus over TCP/IP native. I can’t get the app to connect; Connected to 192.168.1.100:502, but got error: “Port Not Open” I have the IQC Touch display. It works fine with Home A…

Both the IQC Touch and the Gen 3 Remote is currently set to use a RS485 gateway, yes. The reason for it is that when I asked the guys at Östberg, they said that it was the same for the IQC and the Gen3, with both using the serial interface. Since I only have the remote version I just had to go with …

Wow, that sounds great! Looking forward to that. Thanks! :slight_smile:

Could you try the test version ? If you still have the device added, go to the advanced settings and check the TPC/IP to change the communication type. I kept the serial interface in case the IQC Touch unit supports that as well, but any new devices of this type will have the direct TCP/IP enabled …

Awesome! That did the trick, now I have communication. :slight_smile: Fan modes works! “Dial/data” screen crashes the Homey App on Android after 5-60 sec, but works in the web app. “Range Error: Maximum call stack size exceeded”. I have both Homey Pro 2019 and 2023, as well as several Android/Iph…

Good to hear it’s working-ish! :smiley: It sounds more like it’s a bug in the Homey Beta App for Android since that is crashing and not the Östberg Heru app itself, and especially since it’s working in the web app. Do you get the correct values for the target temperatuer and the feedback in either…

Hi, Yes, I think you might be correct here. I didnt’t get the crash on iPhone either (Or web app). I actually got the same error on another Homey app after seeing this the first time with your app. (Airthings, has been flawless with the non beta version) The temp adjustments seems to work fine. If …

I am trying to connect the app, and it briefly seems to work for a couple of seconds after adding the device in Homey. But then almost immediately, the device gives the error “Device Unavailale - Modbus Timeout”. In the Vircom utility that I can use to manage the Waweshare device I see TXD package…

Really happy to see that this app appeared since I last looked into this👍

I assume I will I’ll need to purchase the “Modbus Remote” for my Heru EC 180 to work, correct?
