Hey there @indykoning, @muppet3000, @JasperPlant, mind taking a look at this issue as it has been labeled with an integration (growatt_server) you are listed as a code owner for? Thanks!

in case someone could use this to improve the integration? Growatt Inverter Modbus RTU Protocol_II V1_20-English.pdf

Growatt Integration has stopped working since the update to 2022.8.6. Why are there always problems with the updates?

@Feuerreiter - Have you read the ticket that this is a duplicate of? This is nothing to do with an update, this was a problem on the Growatt Server side. A fix has been merged today and will be in the next release.
There is even a workaround in the other ticket

Vielen Dank.....ich bin beruhigt. Ich werde auf das Update warten. Danke

I agree, it is not the updates - it is the moment you restart the server (because of the update) - then you lose connection and it takes many reloads to get it reconnected, Very weird behaviour :-)
Lets wait for the next update, the current release frequency is so high, it can't take more than a few days ;-)

Thank you for the Statement. I'm always interested in using the current version of Home Assistant. but if there are constant problems and my home management becomes unusable, then I will not do any more updates in the future.

although updating to a new release might be tempting, it is always wiser to wait for at least the first bugfix. I can only admire and respect all the work put into home assistant, but when reviewing the lastest releases, we have already seen 6 bugfix releases.
It is wise to follow "if it ain't broken don't fix it" :-) if you are more or less dependent on your installation.
Exploring new features however is tempting - and the backup restore feature does work pretty good actualy ;-)
