IP Address change Predbat fails to load

[Drewmarkham]

I was forced to change my IP addresses by changing routers. The SSID & p/w remained the same, but the AIO is now 192.168.0.56, it was 192.168.1.144. All other aspects of HA work fine after the change (once I changed the IP address) but Predbat errors. And now fails to load at all.

Part of predbat log that repeats every 20 seconds:

I have tried re-instaling Predbat & GivTcp to no avail. On the latest version of everything. Running HA on PI-400, with 128GB SSD. Currently haven't bothered to amend the apps.yaml to relevant settings as makes no difference.

What am I doing wrong?

TIA

[daviessm]

Please upload your apps.yaml.

[Drewmarkham]

Thx, Below:

apps.yaml

[beezly]

I just had similar

octopus_saving_session: "re:(event.octopus_energy([0-9a-z_]+|)_saving_session_event(s|)"

had a missing terminating parenthesis:

octopus_saving_session: "re:(event.octopus_energy([0-9a-z_]+|)_saving_session_event(s|))"

[daviessm]

Yeah the sample yamls are wrong, I'll do a PR to fix them

Edit: someone else beat me to it!

[Drewmarkham]

Thx. At least it starts. I now have an additional issue:

Error: Exception raised HTTPConnectionPool(host='192.168.0.56', port=6345): Max retries exceeded with url: /readData (Caused by NewConnectionError("HTTPConnection(host='192.168.0.56', port=6345): Failed to establish a new connection: [Errno 111] Connection refused"))

Is this anything to do with firewall rules? (not that there should be any LAN-LAN)?

[daviessm]

"Connection refused" means something has responded to the request, but didn't want to answer it because there's nothing listening on that port. Are you sure that's the right IP address and port number?

[Drewmarkham]

IP address yes. I have doubled checked that. Port number??? That is the one that has always been there, just changed IP address. GivTcp screens etc showing fine in various charts, just Predbat not working?

[Drewmarkham]

Hi - I have had time to sit down and go through the files and managed to track down a typo (done by me ; not : - eyes not good at my age!). And now have 0 errors in predbat, but I still have no charting data and the soc on the plan doesn't increase. I'm wondering what else I've messed up? I have a warning in the logs stating:

Warn: Cannot find battery discharge curve (settings missing), one of the required settings for soc_kwh, discharge_rate and battery_power are missing from apps.yaml

I tried changing line:

soc_kw:
- sensor.givtcp_{geserial}_soc_kwh

to soc_kwh - as I couldn't find any other mention of soc_kwh (it made minimal difference).

Not sure where to look next?

[Drewmarkham]

OK - by changing thr geserial line, between the 2 below:

geserial: 're:sensor.givtcp_(.+)_soc_kwh'
geserial: 'CH2330G046'

I either get 0 Soc% increase (when charge period set), with 0 errors - CH2330G046

or 0 Load Kwh at all, with 21 errors - re:sensor.givtcp_(.+)_soc_kwh

Both still have the warning above +

Warn: Found 1 gaps in load_today totalling 7020 minutes to fill using average data
Warn: Found 9 periods of zero load with power data, filling using power integration

which I presume is linked to another post?
