[BUG] Entities are frequently unavailable in Home Assistant

[DerekSeaman]

Describe the bug
Over the past week or two I'm seeing very frequent (multiple times day) "unavailable" for all Enphase entities in HA.

Account type

• Installer
• DIY / DHZ
• Home Owner (This integration is not (fully) functional with a home owner account!)

Envoy

• [ x ] Metered with CTs installed

• Metered without CTs

• Standard

• FW version: D8.3.5167

• Amount of micro inverters connected: x

Home Assistant

• Version: 2025.11.2

Additional context

Relevant snippet of Home Assistant error log. 

In the past when it was a very rare issue I just did a breaker power cycle of the combiner box. However, that is not working this time. It might restore data access for a little bit, then becomes unavailable. I DID check the box in the HA integration that's for firmware with connection issues.

For me the same, unavailable after update from 10.3 to 11.3 yesterday.Or was it a coincidence?

[DerekSeaman]

@piet1951 Yes, now that I think about it more, 2025.11.x has been HORRIBLE for reliable polling of the Enphase data. Multiple times a day it fails.

Hi! Nothing changed in the integration lately. Are you sure you are using my integration and not the HA built-in one? Do you see any error messages in the logs?
