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.
If you (and the people who want to use these things) are on iOS, you could consider Homebridge
It is easier than a full home assistant install, and may be sufficient for what you want to do.
Home assistant might be overkill for your application (but it can do a lot more stuff)
Home Assistant hates it if you install anything else on your server besides Home Assistant. Don’t even think about running other docker containers besides HA or you’ll get persistent nags and it’ll prevent you from updating without doing workarounds
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.
