PVOutput Alerting question- best way to get an alert if no production data received for 24 hours?

I’m looking for the best way to configure PVOutput to send me an alert if PVO stops receiving production data. Had a problem recently with my Enphase Gateway going offline. Enphase Enlighten didn’t alert me in a timely fashion, and I only found it after a week’s worth of data was not sent. It took significant time and effort to get the missing data loaded.

I looked at the PVO alerts and could not see an obvious choice for how to set this up. What’s the best way to set this up so that PVO sends an alert after 24hrs of no production data?

Thanks for any suggestions.
