Alerts when not getting production data from solar system

Phase 1

Alerts when Home Assistant has not gotten solar generation data from devices in over 20 hours. This will help me investigate issues.

Phase 2

I currently have Sunpower PSV solar generation using a couple of sources in an attempt to cover if one of the sources has a gap, and try to sync and backfill any gaps. The link url https://g.co/gemini/share/0cba7d5e3552 shows the output from some gemini research I am doing around the topic prior to implementing.

Home Assistant is using a travel router and integration with GitHub - krbaker/hass-sunpower: Home Assistant SunPower Integration using the local installer ethernet interface.

and a second source with a Raspberry Pi using GitHub - MrStrabo/Sunned: A SunPower PV Supervisor Poller Script

Curious if anyone in this community has had luck with this type of data merging?
