Ukranian controls Home Assistant over LoRa radio when their power grid goes down

This is the hacker way. Well done to the strong and hearty Ukrainians making solutions for complicated times!

Maybe he could offer this "as a service" using LoRaWAN and a cheap Mikrotik basestation? As a backend Chirpstack can be used.

Very neat setup! I've been using Meshtastic and Home Assistant but never thought to mix the two.

Hey! I have a similar setup. Mostly done as a thought experiment, luckily I don't have to deal with a war.

Instead of using the Python interface directly, I used MQTT as the gateway.

I disliked all the existing MQTT servers (who writes network-facing software in C++!?!?), so I adapted the Mochi server a bit to add support for automatic Let's Encrypt certs: https://github.com/Cyberax/lenc-mochi

One problem is that LoRa is low-bandwidth, so I had to pick and choose what I transmit. I ended up defining a schema that bit-packs all the important (for me) sensor state in just 32 bytes.

As another thought experiment, I'm going to connect it to a pair of InReach satellite transceivers over Bluetooth :)
