I am a beekeeper and I want to put some simple sensors in hives. Temperature a couple times a day and maybe a rudimentary tipping alarm.
Is there an easy way to get this out? My TTN sensor at this moment is the TTN-UNO and it’s just sitting on the bench sending DHT22 data out. I made the application in V2 and also V3. Oddly the first couple days I saw the data in both places, now only in V3. I figure I should stick to V3 and get it running there so that’s alright.
I have setup a Pi Gateway, it’s registered in V2 not V3, it also runs NodeRed. I have used NodeRed before to plot sensor data these were WiFI sensors I built and I used MQTT. It was pretty straightforward to setup. With TTN I setup the MQTT as I read it in the documentation and I do get the data in and I see the temperature, but following the example in the documentation isn’t getting me to a point where I can interpret the incoming messages to make a graph of the data.
Having it on my local Pi might not be the best choice either. Thats just how I have done things before, but I am sure there are better ways. How do you guys get your sensor data out so you can plot graphs and see the history,
