One of the practical applications of Meshtastic is collecting environment telemetry. It would be great if PotatoMesh covers all environment data, supported by Meshtastic firmware. Here is the protobuf schema with all possible sensor fields.

As far as I can see (in Telemetry table in mesh.db) currently only temperature, pressure and humidity are supported by PotatoMesh.

I am only collecting what I know about. Thanks for sharing.

Curious which metrics you are missing? I can add more columns to the table but will there be any practical benefit if nobody actually feeds these cells?

Also, how do we display all available metrics on the dashboard? We pretty much exhaust the possible table width already.

	// Temperature measured
	optional float temperature = 1;
	// Relative humidity percent measured

I have only seen the environmental sensors for temperature, humidity, and pressure on the radio but happy to extend it if you point me to some fields that are actually used. Certainly not soil moisture? 😛

That's what we got in Berlin.

Out of 398 nodes, 6 have temperature, 4 have pressure, and 2 have humidity. I have not yet seen lux or wind or soil data.

Well, I'm a bit biased 😁 since I just converted my weather station to pass data to the mesh by protobuf encoding unsupported sensors. I have now rainfall, wind speed and wind direction and solar battery power, on the top of what you mentioned. Check the readme in my repo to see what I mean.

The trouble is that Meshtastic supports limited variety of sensors (mainly i2c) and this restricts the applications. That's why I figured out how to inject unsupported sensors' data (so long the firmware has such data type).

I could contribute to the potato-mesh ingestor part, since it's Python, but can't do anything about the web (Ruby) part.

Well, it could be visible in the popup on node click on the map only. You don't need to show it in the node list table. More importantly, the GET /api/telemetry would be a very nice endpoint for getting these sensor data for visualising (or storing) them somewhere else.

You can test #385 if you like and verify the data exists in database or /api/telemetry/${id}

It does not yet show in frontend but can create a subsequent patch if it works

I think it's working good. I can see the wind speed and wind direction on the web API point. Battery sensor is not connected yet, and it's not raining currently, but I assume those would work too. Thanks for the speedy action on this 👍

That is so cool!

Which weather station are you using if I may ask? I also have a Meshtastic node on a Raspberry Pi, maybe I look into that!

I want to broadcast soil moisture over the Mesh ;-)

It's a custom one I made, running micropython code. The sensors are from Aliexpress. I have adapted the Raspberry Pi weather station tutorial python code, to work on the Pico with micropython.
