RadioHead VS MySensors

If you do not use WiFi (though I would) and have to fall back to 433Mhz or similar RF signalling then look at the Radiohead library rather than reinventing the wheel.

These 433 style boards are the ones I would look at (range being a possible limit) - maybe using the RadioHead library and front end the Pi with a dedicated receiver board if you cannot find a compatible Pi library.

You need a networking stack. There are some good examples out there; I remember the RadioHead library from years back. I think someone said it sucks and use this other thing instead but I can't remember what the other thing was. You'd write a driver that performs modulation with the HackRF, then use the rest of the stack to do the packetizing and retransmission and stuff.

As mentioned, chirpstack works well if you still want to use LoRaWAN. Alternatively, you can use a system such as https://www.mysensors.org/ which builds its own protocol on top of lora. Finally, you can write everything from scratch using radio libraries (eg: https://www.airspayce.com/mikem/arduino/RadioHead/)

I have a project where I use LORA with the Radiohead-library (http://www.airspayce.com/mikem/arduino/RadioHead/) to gather data from various locations, and then publish that to the web.

I would take a look at https://www.airspayce.com/mikem/arduino/RadioHead/. I have not personally used this and it is not free for commercial use, but it is one option for providing higher level network functions.

You also need to determine if there is any kind of a conflict between these various packages you are using such as a pin number, etc. See RH_RF69 send hang due to waitPacketSent failed · Issue #12 · PaulStoffregen/RadioHead (github.com) So you need to be able to do testing with status messages to Serial so that you can see those logs.

Engineering implies working within constraints. Most people in this realm only have to deal with the spouse acceptance factor as a limiter.

Went from openhab -> homeassistant -> Node-RED. Then sprinkle in MySensors, Frigate, and Double-Take, but not on just the entrance, go for the perimeter then defense in depth.

Mestastic has been doing fine work. I'm not a fan of the CLA though.

MySensors, IM(very)HO is a better system if you are building your own gear. They too have CLA requirements.

If you like the idea of a smart home but worried about the S in IOT check out MySensors.

I have had great fun and good use of MySensors, that could be a place to start. It’s a very friendly and supportive community.

If you haven't already defined your sensor modules, have a look at the MySensors framework. It works via a tree network where every node works as a repeater so you can easily build a large and sparse network with encryption at very low cost. It also integrates seamlessly with Home Assistant and most other HA controllers. I've used it at home with good results and it supports the RFM69 radio using India frequency bands.
