Never looked in to deeply how haos manages things.

I never used hacs since I’ve heard it complicates setups and maintenance and I don’t want to put in more effort than I absolutely have to (working as it pro and don’t need that privately). Running several integrations, Enphase as stated, airthings, broadlink, esphome, homekit, melcloud, nanoleaf and the main one for me, zigbee.

Speed when booted is perfectly fine, can’t say otherwise.

What specifically is slow?
