PredBat doesn't start (KeyError: 'stamp') in v8.22.6

[murkle]

PredBat hasn't been starting up for a few days and I've got this in the logs:

2025-07-13 19:23:27.058499: Octopus API: Fetching intelligent dispatches for device 00-1C-55-00-00-05-4C-C7

KeyError: 'stamp'

I've "fixed" it by commenting out these lines in predbat.py and octopus.py

#        if url in self.github_url_cache:
#            stamp = self.github_url_cache[url]["stamp"]
#            pdata = self.github_url_cache[url]["data"]
#            age = now - stamp
#            if age.seconds < (120 * 60):
#                self.log("Using cached GITHub data for {} age {} minutes".format(url, dp1(age.seconds / 60)))
#                return pdata

#        for url in list(self.url_cache.keys()):
#            stamp = self.url_cache[url]["stamp"]
#            age = now - stamp
#            if age.seconds > (24 * 60 * 60):
#                del self.url_cache[url]

possibly linked to #2560, there have been changes to the Octopus intelligent API?

[pacemaker82]

@murkle did you upgrade to 16.0.0 of the octopus integration?

[murkle]

@pacemaker82 I'm not using https://github.com/BottlecapDave/HomeAssistant-OctopusEnergy/ (just the direct PredBat integration)

[pacemaker82]

OK it won't be related to https://github.com/springfall2008/batpred/issues/2560 then

[gcoan]

OK it won't be related to #2560 then

I suggest that it could be the same underlying issue, Octopus has changed the API, the Octopus Integration has been updated (v16) to accept the new API format, but predbat hasn't been (yet)

@murkle swapping to using the Octopus integration may be a workaround in the short term

[pacemaker82]

The octopus api doesn’t change until August so if using the built in integration all should be OK I think. Only using 16.0.0 Octopus Integration will cause an issue if there is one, because fields are missing when switching to the new API which only 16.0.0 supports

This looks like a corrupted yaml file in 6adb40d_predbat/octopus.yaml

Please delete it and try again

@springfall2008 I don't have that file, what should it contain?

I still have the same error with v8.22.7

Sorry I mean This looks like a corrupted yaml file in 6adb40d_predbat/cache/octopus.yaml
