Non Meshtastic Ideas
1

I understand that meshtastic can be used “headless” (without a cellphone). I would like to use the technology to monitor my walk-in freezers (temp/humidity/power). I would like to send MQTT packets either over the local wifi or when the internet is down over the meshtastic network.

I am looking for advice on what hardware would be best suited for this use case. It would need battery backup (that is an easy one).

Also I might need to set up mechtastic routers as well for coverage.

If you need wifi on every node, that limits your selection to these three. Seems the LILYGO LORA would be the cheapest and would probably fit the bill; this, along with the Heltec LoRa32 don’t include GPS.
