Hi, I’m looking for a cheap… (switch, lightbulb, etc.)
I haven’t found one list but that would be the typical question here, right?
If there is one please point me to it, if there isn’t it would be nice to have a list with devices, prices and protocols for the new user to know what to buy first.
Welcome to the board. In short HomeAssistant is a piece of software that can tie several smart product together and control them depending on a set of rules (automations.)
As such homeassistant doesn’t have a set of devices to buy. The way to go would be to define what you want. For example a light. You can then choose for a zwave light, hue light, lightify. Once choosen you can lookup how to hook that up to home assistant…
Speaking for myself: I don’t think this is the right place to request such a thing. You mention there are millions. So there is no way here to keep track of that.
I think you need to do a lot of googling. Decide for yourself what you want. Check if there is support from HomeAssistant and take the dive…
