I use one of these as a gateway that receives LoRa messages from my sensors connected to these. I use the gateway to publish the LoRa packet to MQTT running on my RPi server but could just as easily push the results directly to a cloud dashboard like Cayenne, UbiDots, Thingspeak.
The LoRa32u4 is using a BME280 to collect Temperature, Pressure, Humidity & Light Level (using LDR) and formats this into a JSON string along with the battery VCC). It collects values every 5 minutes but only publishes the averaged results every 30 minutes and sleeps as much as possible between. With this I was getting 30 days use on a 700mAh Lipo. I have just started to test using a 18650 Lipo but have not got to the first discharge cycle yet so don't know how long it will last but I'm hoping at least 3 months.
The gateway is powered all the time and is connected to my Wifi. When it receives a LoRa message it checks its from my sensors (I receive other signals that are not mine) and publishes the payload (JSON string) to MQTT along with the RSSI & SNR or the received packet.
I have an RPi Zero Wifi configured with Mosquito and Node-Red that uses a flow to read the MQTT messages and then publish the results to the NR dashboard and also push the results up to Cayenne, UbiDots, Thingspeak & Dweet.io
I also have other BME280's connected to ESP8266 boards (in the house where they get wifi) that also publish the same sort of data to MQTT
