Not getting updates for Custom Integrations installed via HACS

Hi - I’m aware this is similar to some issues raised previously - I have used the suggestions provided there to investigate but no luck so far. The issue is that I have the new look HACS installed but am no longer getting the frequent alerts for custom integration updates that I used to get and some integrations, such as the Octopus Energy one, are way out of date. I am getting update notifications for Home Assistant Core, OS and Addons.

I can see the integrations in HACS (I am running v2.0.5 with Home Assistant Core 2025.4.3) - there are no Repairs, my DNS servers are the Google ones. I’m confused and would be grateful for any helpful suggestions!

Thanks,
Steve.

A follow-up to this - the integrations show up as ‘Available for download’ despite already being installed. I’ve tried re-downloading Pirate Weather and it seems to install OK and work as expected. Surely there is an easier way to do this though, as it requires me to manually go through all the custom integrations and re-download. I can do it, but I’m sure that’s not what was intended.

Seems there is something wrong with your Hacs installation, I do receive update notifications. Maybe reinstall Hacs.

I’ve reloaded HACS, no difference. Will deleting and reinstalling HACS affect my currently installed custom integrations? I might give it a go after a backup.
