I own a couple TP-Link Tapo Wi-fi light bulbs. Currently, each family member installs an app on the phone to control the light bulbs. I wonder if there’s a way to do the same but in a browser (via docker app on my NAS). And because we may use smart devices of other brands in the future, it seems too much trouble to install yet another app on each phone.
I am running home assistant as a docker. I also run >10 other docker containers on the same server. It works fine. There are minor issues (like the „add to my home assistant“ button on the website does not work) but it is far from what you are saying.
