Hildebrand Glow - stuck unable to install HACS

Third party integrations Node-RED

I'm trying to set up energy monitoring for my electricity supplier Smart Meter using the Hildebrand Glow display.

I can see some energy sensors which seem to be what I expect, but all values remain zero. I can see messages at /config/MQTT on the 'glow' topic which seem to match the sensors and do have non-zero values.

So I've been trying to install HACS as there's a community integration for this display. But using the Get HACS app is failing with the following errors in the supervisor log:

2026-06-07 16:25:18.496 ERROR (MainThread) [supervisor.docker.interface] Can't install ghcr.io/hacs/amd64-addon-get:1.3.1: [500] failed to resolve reference "ghcr.io/hacs/amd64-addon-get:1.3.1": failed to authorize: failed to fetch anonymous token: Get "https://ghcr.io/token?scope=repository%3Ahacs%2Famd64-addon-get%3Apull&service=ghcr.io": net/http: TLS handshake timeout

Can anyone help?! I've used the wizard to set up the Energy view (?) but as expected the values are all zero so I guess there's a disconnect between the sensors I see in HA and the MQTT messages I can see at /config/MQTT

I followed this guide to get this far, but am not able to do the step of installing HACS and the Hildebrand Glow integration because of the above error.

The two issues may actually be unrelated:

  1. Your HACS installation is failing because Home Assistant can't reach GitHub Container Registry (ghcr.io).
  2. Your Glow MQTT data appears to be arriving, but the Energy dashboard isn't using the correct sensors.

Thanks. I can see that but what I don't know is how to fix this, particularly 2.

Those sensors appeared when I first got the Glow but before I could test it properly because it was not yet connected to the meter. So I assumed once it was connected, they would have data and beging working.

So I'm not sure why that has not happened, or how to get rid of them and replace them with the working sensors.

EDIT: I think the problem with HACS was just a bad internet connection so that is now installed.

I sorted the rest by getting rid of the MQTT broker and its devices and using the following community integration which correctly detected my Glow, and added the correct entities unlike the examples which I was following earlier:
