Hello Werk,
thanks for your feedback to my suggestions. I also understand your concerns to get representative and traceable readings of the environmental conditions (which is mostly expensive).
Since I'm working in a lab doing also environmental tests, I know that a calibration of one measurement device costs often more than 1000 EUR...
Nevertheless I'm always a fan of trying new things to get also reasonable results with a small budget.
Concerning the soil moisture sensor:
I also did a bit of research before posting to find out that the soil moisture is indicated by a (negative) pressure value to quantify how much force the plants roots need to get some water out of the soil.
During research on the Vegetronix system, I was linked to this sensor and in principle i thought this could be useful.
Of course it is necessary to compare both systems and to work out how to calibrate and adjust the proposed sensor to get reliable readings.
That's why I was asking for the principally willingness to integrate new sensors.
From this point on it is in my opinion useful to invest more time and do some research how the sensor could be used or if it is not appropriate after inquiring the behaviour.
Concerning the BME 680 VOC:
This is a bigger problem because the sensor can not differ the different components. At least it is acknowledged that VOCs have an impact of the indoor air quality

Bosch has its own algorithm to calculate a AQI out of the sensors data.

On the one hand you are right that I don't know on which studies this calculations are based on.
On the other hand it would be an easy chance to gather some information about the indoor air quality, since the hardware would be plug and play.
Best regards,
