Re: Air Quality unit - which devices are best?
There is also a somewhat newer Sensirion SEN55 (shop link) combined sensor, that has many of the sensors you want to use, but has some overlap with the SenseAir S8, but the SEN55 doesn't yet have support in ESPEasy... :oops: (sorry for the teaser ;)) Actually, there's no overlap between SEN55 and S...

Re: Air Quality unit - which devices are best?
From the sensor side, I would recommend SCD40/41 for CO2, temperature and humidity, they are almost as precise as SensAir while cheaper, more compact, and less power hungry. SEN54/55 can be added for PM and VOC measurement, or it can be PMS7003 and SGP40/41 combo. I had to flash Tasmota to test SEN5...

Re: Seeking Advice on Integrating LoRa Project into ESP Easy

Re: ESP won't go into Deep sleep just when GPIO16 is pulled low?
I think something may be wrong with your module. ESP easily falls into deep sleep with GPIO16 floating or pulled down. Proven on a bare ESP-12F module. Second, GPIO16 in ESPEasy is an output. This means that you can connect two outputs (GPIO16 and, for instance, PIR) only if they are normally in hig...

Re: ESP won't go into Deep sleep just when GPIO16 is pulled low?
I believe GPIO16 is an output internally connected to the RTC timer and affects only wakeup behaviour when connected to Reset input. ESP should go to sleep by a command regardless of what's going on with the GPIO16. Then, while sleeping, an on-off pulse to Reset pin will wake it up. So, if you use t...

Re: BMP280 Accuracy – Four sensors, four values – How to calibrate?
This is very common with all BMx sensors regardless of where they were purchased. Basically, they all exhibit positive offset of up to 3 degrees.
You may calibrate them by two points, the large the distance the better. The resulting coefficients could then be put into the formula field of the task
