GivTCP mqtt_client - [ERROR ] - No serial_number found in MQTT queue

Hi All,

First day at attempting to get HA running (BIG thanks to a number of the content creators on YouTube for some very helpful videos)

X86 machine, runnning HAOS
Inverter: GIV-3HY-11
Software Version: DA0.007-DD0.007-A0.007

Progress was not too bad until attempting to obtain the parameters from the Inverter.

Using GivTCP and MQTT Broker

Serial number has been obtained, so from that I have to conclude that communications has been established succefully, at least at the beginning

I've seen other posts in the forum from people with simlar issues - so this may have already been posted (appologies) but I've running a Three Phase Hybrid inverter, so checking to see if anyone else has solved this on my inverter.

NOTE: I see similar issues with the GivEnergy App - the HOME connects but can't obtain any data, but the AWAY connection works fine. (Feel these may be linked i.e. suffering the same connectivity issue)

Are you definetly running GivTCP 3 onwards - the TCP library only recently supported 3 phase inverters - I can see that the error log shows it thinking its a Gen 1 hybrid so this may be where it is getting hung up.

TrevorD As Hoggy says you need to be on Giv TCP v3, the latest is 3.0.4 for a 3 phase inverter.

I’m not sure it is perfect yet but there are others using it. Have a look at the github givtcp issues and see what others are reporting. You could well need the dev or beta build as its still WIP

Thanks - I did try to reinstal the GivTCP 3, but what I selected must have been wrong.

So I'll try agains, I'll get on that and post progress once I'm sure its using the GivTCP 3

Thanks

Trevor

TrevorD Make sure that you untick auto start and shutdown v2 or uninstall. Can’t run multiple givtcp’s together !

I've just uninstalled... hopefully that killed it

BIG THANKS...

I'm up and running...

I'd missed the need to add another repository to see the V3 version

Anyway - thanks

TrevorD yes the add on location changed for v3, it does make it easier to install the dev or beta versions now though

Glad you got it sorted
