Devices stopped responding after few days

[ishikht]

Hello guys,

I'm facing issue with my devices, devices are not able to execute local API commands on /api.cgi, and it's impossible to locate devices by UDP multicast. They are still accessible from the cloud API (mobile app and my.terneo website).
This was caused by running this integration in HA, as I'm not using anything else.
The problem occurs every 2-3 days, and not with all devices at the same time. I have 6 ax and 1 sx devices, since Monday 2 ax are off, rest are ok.

Probably the problem related to devices firmware.
But it's started to be impossible to use your integration as the only one way to reboot a device is to cut off power.
Please let me know if can help somehow from my side.
Thanks

Have a very similar issue. Described here: #10

I had the same issue with config from the example. Now everything is ok after removing any '' signs from the parameters.

I've made my own kind of HA integration, where I faced exactly the same issue. So, looks like it's a firmware issue.
At the moment I did make it work by using a mix of cloud API and local device commands. Once a device is unresponsive (actually device just returns an empty string) I just collect telemetry from the cloud API, same with device management, it works perfectly.

@ishikht also can be controlled via mqtt, maybe this approach have a less problems

[ishikht]

@Makave1i to be honest I tried, few times, but it doesn't work as expected. MQTT has a disadvantage, telemetry sent by a device doesn't contain powerOff state (local API and cloud API has that state ), and the device continues to send MQTT telemetry even if the device is off.

So, if you turn off the device in any other way than by MQTT, you will never know the device off. As result, in Home Assistant, it's impossible to set actual hvac mode and hvac action.
