Home Assistant Missing Addons

Morning All,
I’m very new to home-assistant. I’ve had some sonoff switches for a while, and have been using them with Alexa, but the wife hates “asking” to turn the lights on.

I’ve got a couple of old tablets laying about that I plan to set up in “key” rooms to use as switches and automation, however, I’m struggling to get past the second hurdle. (I think the first was flashing a couple of the spare SonOff’s with Tamota (DONE!) -

I’ve installed Home assistant on my unraid server on docker, however, when I log into the home assistant I don’t seem to have the Hass.io store to add plug in’s. Am I doing something very wrong?

I fully understand your wife, mine is the same. Therefore I invested in new switches that both can be used normally and controlled by HA

Thanks for the help. so from what i’ve just read the store isnt available from the docker, and i guess it cannot be added. What switches can controlled by alexa, and HA?

I’m still trying to configure HA to be honest. just struggling a little. I could do with a start to finish how to guide for connecting the flashed sonoff switches, and then connecting alexa to them. The only thing i’ve managed to setup and control from HA s far is my Denon Amplifier. I don’t even seem to be able to get Emby working.
