I have been getting my feet wet with LoRa, and found this button box below. With a very wide range and long battery life it could be ideal for placing at the end of the garden to control garden automations like lighting or watering systems. Interested if anyone has tried it or similar on LoRa?

Hello, it is possible to create LoRaWAN sensor that sends messages to LoRaWAN gateway and the gateway then sends HTTP POST to Home Assistant. I can send you code for Arduino that measures battery level, you would have to figure the rest because it depends on LoRaWAN provider. I have good experience with it, it runs on battery for about half year now.
It is possible by MQTT with a LORAWAN gateway with a builtin LORAWAN server. Outside of this architecture you will find most of the time a LORAWAN server on the cloud so as to process the messages and forward them to third parties applications.
For HTTP I have never tested.
Hello, I think that limitation of LoRa is about 56 bytes (for slowest data - longest range), so you cannot send whole MQTT payload. Have you actually tried it?
MQTT is not used in LORA or LORAWAN transmissions. It can be used outside of them by the gateway or the server.
What do you mean by MQTT payload?
