Can you try to verify if ip and port are correct?
For example using telnet 192.168.1.100 8889 (change the IP to that of you heatpump)

Someone in the past had the same problem and it was an incorrect ip / port.

Also older versions used port 8888, maybe thats the case for you.

This works. I get an online status via telnet and the port 8889

How do you run HA? HAOS? Docker Image?

from luxtronik.

HAOS, Version
core-2021.9.7
This haos runs as vm from proxmox

from luxtronik.

Can you verify that you can ping the heatpump from within the HAOS container?
I run HA as docker container and need to run this specific container with network_mode: "host" in order to be able to connect to the heatpump.

from luxtronik.

do you know how to do a ping on haos console. Seems there is nothing installed

from luxtronik.

I've never used HAOS before but I guess thats your way to get shell access to the OS:

from luxtronik.

from there you should be able to use ip a to verify that you have an IP withn the same range as your heatpump and maybe there's ping installed

from luxtronik.

I got the ping to run. And yes the heat pump reply's: ping 192.168.1.xx

64 bytes from 192.168.1.xx: seq=0 ttl=63 time=1.906 ms

from luxtronik.

Ok thats from the OS, to my undertanding HA runs as a container within the OS.
I don't know how to get acces to that, but as a workaround you cound use the ping itegration to see if you're able to ping from HA:

Hi Bouni, I tried the ping and yes you are right, No connection possible. I googled around a bit, but found not really a solution for this problem.

from luxtronik.

I did some settings in proxmox hardware adapter for the network. There was a switch to turn off dedicated firewall. No it works :)

Thank you Bouni for your support
