DIvision by Zero error

[MicroDraco]

The connection between the RPi and home assistant dropped while the solar panels were not producing anything. When the integration tried to reconnect, it fails repeatedly with the following error.

This error originated from a custom integration.

ZeroDivisionError: division by zero

The connection cannot be re-established.

interesting its not getting any frequency measurements but also 'duh' that shouldn't be dividing that way unprotected.

I've begun to hit this identical error as well.
Nearly 2yrs without issue and now this "division by zero" issue blocks the custom integration from loading.

[chriswood1001]

The good news is that it self recovered after 48hrs without intervention.

I just started seeing this as well about 5 days ago, has not recovered. Havent dug in, just confirming its still an issue
