Hi. I recently realized that the weather station I have (Acurite Iris 5 in 1 but not one that connects to Wi-Fi) communicates over a 443 mhz with its display and I should be able to grab that info and add it to HA. I know I'll have to use MQTT and a USB tuner but after that I'm kinda out of what I know. My HA is in a VM on my unraid server, would it be best to host MQTT in a docker container there or should it be inside the HA VM or on its own hardware like a pi? Any info would be great. Any links to some resources would be appreciated as well

I at least saw this video:

Add Acurite Sensors to Home Assistant

Home Assistant has lots of options for getting weather data, but a lot of them are cloud-based. And while that isn’t bad, it does introduce some risk. Weather Underground, World Wide Lightning Network, and Darksky have all announced they were closing their APIs or moving behind a paywall in the last year or two.

In your case it shouldn't really matter where you host the MQTT broker. You could just use the Mosquitto addon.

Then would I have to pass through the USB tuner in unraid to my HA VM? I'm guessing so since I had to do that for a zwave stick but what to just double check

Not necessarily. A service using MQTT and the MQTT broker do not have to be on the same host. They talk through the network.

I thought I figured it out but I didn't. I believe I got my MQTT broker (Mosquitto) set up and the addon from the video I sent. I just can't get the 2 to talk. I think I might have over-complicated my setup by having my HA in a VM on unraid but that's already done. I almost want to say that I am using the wrong IP address but I have tried multiple ones it could be and not much change. I've tried my server IP, my VM's main IP, then I tried what I believe are 2 internal to the VM IP, and I've even tried my domain address (didn't really think it would work but it was something to try)

You should be able to use core-mosquitto as address. The ip of the VM should also work. Check with MQTT Explorer if the broker works properly.

That might have worked but on the addon side of things I'm not getting a connection successful message

#

I connected to it with MQTT Explorer and now it showed up in HA. Not quite sure on that one but not mad

#

The addon log still isn't saying connected but the device and entities are there so.... 🤷‍♀️

I can't help with the other addon but if it works that's fine, I guess.
