The app has a setting to disable or relax the polling on the safe guard, try playing with that
Slow it down or disable to see if that makes the rest work again
Still having a hard time getting it to work even on 1.3.6. Are you aware that the Venus E 3.0 does not support multiple hosts? At least it seems that is does not. Could it be that your app has multiple instances connecting to the battery? Preventing some functions form working?
I am, it is clearly focused around the v3 utp connections, so it is something like that. But I think I don’t have multiple connections, at least my ew11 only shows one for example.
I don’t get feedback on if the disable the safe guard does anything
Check. Yeah I am sorry but I have not had the change to get any battery working on the test firmware. As soon as I change anything the Modbus communication seems to stop working. Even disabling the safe guard polling aswell as bumping up the time does not bring it back. But I also have this 1.3.6. After restarting Homey, the app and the batteries multiple time I might get them back working. Once its working it is fine for hours.
So removing the playing arround with safe guard settings does not seem to fix anything there. Because of this I have not been able to see if the dips are also better with the test firmware
I don’t ship firmware 
, let’s keep the info clean.
Because I am going to ask: did the marstek ship new firmware?
Ah yeah my bad 
I mean the version of your app. Battery firmware has not changed
Iam on the test verion of your app atm. But I cannot get the polling working. Can I provide you with something to help debugging?
I think I have to revert to the version before 
.
Now I just have to figure out what the version was that was stable
Hi
Installed version 1.3.14, when changing charge mode resulted in time outs.
I disabled guard and communication is up and running.
I set the guard again “on” and fast check interval on 30000: keeps working
I changed the interval in steps to 500, communication keeps working
Interval 500 is minimum to change to.
I will keep this setting to see if it will be stable
