How many of you host your IOT software in the cloud? (lemmy.world)

As an example: some people might be using the offerings from Microsoft or Amazon, whilst other people might be running a VM with a VPS somewhere and hosting their apps like Homeassistant, OpenHAB, Node-Red etc there.

I wanted to know if you do something like this, and what might be the downsides to doing something like this.

Thanks!

Good luck connecting all of your IoT devices to the tailnet though. You'll need a firewall and lots of tinkering. I use linode and host some stuff in the cloud, but not Home Assistant.

What do you mean? Isn't this supposed to work similar to a direct VPN connection to the VPS box, i.e. akin to the machine being in the same network? Am I missing something? What do you mean by "firewall" (on my side, or on the side of the VPS)?

I'll likely be using Node-red and MQTT with some automation apps, probably. Not decided yet.

Tailnet requires you to run the Tailscale client. I would bet that the Tailscale client isn't even built to run on some/all of your IoT devices. Even if it were, I doubt many little esp devices would have the overhead to run them.

I suppose you are right, but if I install a tailscale on my router like so, wouldn't that work?

[–] lambda@programming.dev 1 points 2 years ago (1 children)

It just might. That's what I meant by firewall btw. A router is usually just three things, a firewall, a network switch, and a wireless access point. The part that handles routing to the internet (and your cloud instance) will be the firewall. I have OPNSense as my firewall with Tailscale installed on it.

Thanks. If I install tailscale on OPNsense I should be able to connect my IOT devices to the VPS.
