Dropping some science on the garden today.

I've been testing a pair of these plant sensors for the last few weeks and decided they were useful enough to get more. During testing I found that sensor 2 showed odd readings for light level. Placed right next to each other, when the light level was below 10k both sensors showed approximately the same value, but above 10k sensor 2 was off by a factor of about 2.75. It still followed the same pattern, so it seems like a calibration error.

I got 6 more sensors and placed them all next to each other. Now I'm giving the sensors a chance to stabilize and accumulate data. We'll see how consistent the readings are before putting them in their final locations.

These are branded VegTrug, but I've seen them as Xiaomi Mi Flora, and Flower Care. The model is HHCCJCY01HHCC. They're not going to be a simple turnkey solution though. They're bluetooth with a short range and I'm using ESP32s powered by a powerbank (good for a few days) to get the data back to Home Assistant and Grafana.
