How many of you host your IOT software in the cloud?
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.
Home assistant is already a mess to properly configure in the lan where the auto discovery does most of the job, doing it in the cloud under a VPN (because you don't plan to expose the iot devices to the internet, right?) Increases the complexity for no benefit
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.
Tailnet appears to be Tailscale which is Wireguard underneath. This means it operates at layer 3 (IP). However a bunch of smart home stuff (mDNS, WoL, etc) all depend on layer 2 connectivity (same subnet).
