@mutmut thanks for the logs, they are quite telling 
1. The progress bar — Indeed: out of the ~4 minutes, it’s the Frigate image download that takes ~3 minutes by itself (the rest is almost instantaneous). Good news: even if it’s « a single step », Docker gives us the download progress — so we’ll display a real bar « Downloading Frigate image… X % » during these 3 minutes, plus the labels for the following steps (MQTT broker, configuration, startup). It’s in preparation.
I reproduced it by launching the image on a raspberry-pi, roughly the same time as you for the installation.
2 & 3. The MQTT brokers / the name eclipse-mosquitto — we agree. The broker dedicated to Frigate is a conscious choice (isolation, dedicated credentials), and mosquitto is ultra-light (a few MB), so no resource concerns. For the question « what if we shared / named it better », it’s exactly what Pierre-Gilles is preparing on external container integrations — the right place to discuss this is the dedicated topic where it’s being discussed: Intégrations externes dans Gladys Assistant
4. Your Intel HD 530 iGPU — yes, it’s already supported: the integration automatically detects the Intel GPU and enables acceleration (video decoding + OpenVINO detection). The only condition depends on your setup: you need to expose /dev/dri in your Proxmox LXC container and then in the Gladys Docker container. Once done, let me know what the « Hardware Acceleration » section of the Frigate configuration page displays — we’ll validate it together.
5. Restarting Frigate — same principle as point 1: we’ll display « Frigate restarting… » then « Frigate operational », based on the signal that Frigate sends us when it’s back online.
6. Your Myfox — the message connection refused …:554 means that the camera itself is not responding on this port: it’s indeed on the camera side that you need to « fiddle », as you felt. The red banner « No stream received » is there for that. We’ll also enhance the « Suggest this camera for the catalog » button to automatically include useful logs (Gladys, MQTT, Frigate, go2rtc) — this will allow us to help you much faster in such cases, and to add your Myfox to the catalog.
And I won’t forget to check if the eufy Security Solar Wall Light Cam S120 can be easily supported before you buy it. But without testing, I don’t think I can confirm 100%…
