Exception: 502 : error communicating with the backend, when hitting start about hass-gardena-smart-system HOT 6 CLOSED

This is probably a bug that has been resolved in the latest version of the gardena library in your homeassistant installation folder. The error message provided from Gardena API is not really clear, but most likely it is the fact that your mower ID is applied wrongly with the start call.

How you can verify if this is the case.

On your home assistant server go to the following directory:
/usr/local/lib/python3.8/site-packages/gardena/devices/

Open the file mower.py

Loog for the functions "self.smart_system.call_smart_system_service(self.id, data)" and replace it by "self.smart_system.call_smart_system_service(self.mower_id, data)"

After a reboot of your home assistant server, the control will work.

Or you can reinstall this gardena library to the latest version and then this should be fixed.

I had also the 502 error, but when updated to v0.2.1b3 it worked fine.
No more 502 errors and the mower responded to the commands.
Then there was an update to the newest v0.2.1, again the 502 errors appeared.
So i rolled back to v0.2.1.b3

@grm, i was about to message you, but i comment on this issue since it relates, exactly as ronbrou writes.

With the latest 0.2.1 i got 502 error back.
Work around for now is to install 0.2.1b3 as suggested above.

yeah. change from version 0.2.1 to 0.2.1b3 did it for me, too.

Hello,

Sorry for the late answer. I am currently abroad with very limited access to my emails and internet !

I probably made a mistake in the lastest stable release (my plan was to promote the 0.2.1b3 to a new 0.2.1, but i probably have done it too fast).

In order to solve the issue, I deleted the latest release (0.2.1) and promoted the 0.2.1b3 to a stable release. It should permit everyone to make the integration work !

I'll have a deeper look on the why as soon as i have a better connection (probably beginning of september).

Sorry everyone for the issues !

Should be fixed in 0.2.2.

Do not hesitate to re-open it if the issue persists ;)
