britkat/giv_tcp-ma: Really basic help needed

Hi - I posted a few months ago but have not been able to revisit - so am starting from scratch again.

• GivEnergy AOI (13KW) + Gateway
• Both GivEnergy Devices connected to same wifi network - 192.168.x.0-255
• Windows 10 Laptop - connected to same wifi network
• Docker Desktop - Latest
• britkat/giv_tcp-ma - Latest

Docker configured in host mode - (as of Docker 4.3.0) - as have read that "should" help.

docker run --env-file env-basic.txt britkat/giv_tcp-ma

where the config file has

INVERTOR_IP_1=192.168.x.y

The port 8899 is open on the inverters IP - confirmed via nmap and telnet

When I start Docker I get

'docker run --env-file env-basic.txt britkat/giv_tcp-ma

with '2024-06-07 09:47:41,609 - Inv1 - sync - [ERROR ] - Connection to (192.168.x.y, 8899) failed: timed out

then repeating.

I know I am missing some basic - loads of people have this working - what am I doing wrong?

Thanks in advance.

SnowDeer I don't use giv_tcp, but the last bit - connecting to 192.168.x.y port 8899 - is almost certainly the connection to the inverter over modbus - I'd double-check that you've configured the IP address correctly

There was only 4 devices on the network - the router; the laptop and two other devices; both GivEnergy - one the gateway and one the AOI. I tried both in the spirit of ruling idiot error out....

SnowDeer
It's hard to suggest what to look for without seeing your full config. Why not share that?

Some obvious things to check - you have NUMBATTERIES_1 set to 0; you have the IP of the AIO unit (not the Gateway) as the INVERTOR_IP (and you have spelt INVERTOR that way!)

Hi - Thanks for the replies etc.

For anyone else struggling and for my own piece of mind - this is how it was resolved....

1. I had over the attempts to get stuff working played with different docker networks and so on; you do not need to have a host network - it works fine with a bridge.
2. Whilst I could connect to the AOI ports from the base Windows Host - I never tried from within the actual running Docker container; my assumption was that it would connect - in reality it could not connect. Reason: Point 1.
3. I uninstalled Docker Desktop and re-installed to have a blank canvas
4. And after a few plays came up with (based on previous advice received - thank you -

docker run -p 6345:6345 -e INVERTOR_IP_1=192.168.x.y -e NUMBATTERIES_1=0 -e INVERTOR_AIO_1=True -e MQTT_OUTPUT=False -e INVERTOR_AC_1=False -e WEB_DASH=True britkat/giv_tcp-ma

and it runs the web dash board fine - the Port 6345 returns data as per the documentation and whilst I have not yet played with the REST interface for control a GET request to http://localhost:6345/setDischargeSlot1 returns Method Not Supported (which seems perfect as I imagine it only wants a POST)

so I hope this helps someone.

Cheers

Is there a specific reason why you're not using a docker-compose file for this? In my view it's a lot more friendly to manage. Just curious.

Hi - in answer to your question about a compose file - mostly ignorance ;-)

Just followed this guide https://spacelift.io/blog/docker-compose and can see the benefits - especially when multiple interconnected containers - but I was (at least initially) just trying to get the singular giv_TCP-ma docker container to connect and work - which thankful it does now.

But could I ask - could you share some of how you are using Docker Compose / other bits and pieces with Giv_Energy kit? Maybe I'm missing a use case / way I can use it all - and happy to learn!

Thanks

SnowDeer could you share some of how you are using Docker Compose / other bits and pieces

There's a whole world out there!

Here are some containers that I use in my main docker-compose (along with givtcp):

• dozzle (for examining docker logs)
• portainer (for managing containers)
• growatt (for my Growatt inverter)
• givtcp-beta (for testing)
• home assistant (most people don't run this is Docker)
• mosquitto broker (as above)
• appdaemon (as above)
• influxdb (a time series database)
• grafana (graph display from database)
• uptime-kuma (inform if something goes down)
• owncloud (local Dropbox-type storage)

Plus a large number of containers for media retrieval, management and viewing - which is a whole other story. Plus a reverse proxy (traefik) for external access, with security (authelia)
