I would really like to get OTA working here as it's freezing outside and I have to go there to update the software in the greenhouse control system.
So please, can we have a 'how to' step-by-step guide to OTA? Please?

as I experienced, MQ sensors are not really gaz sensitive, they are more particle size sensitive when hot enough and when not totally scrap.
I would not rely my life on them, if you have an alcool spray use it around and any MQ will to go the sky...
Hello
I still didn't figure it out exactly, what is the issue with LGT8F328P and arduino, but for start, it can work, if you define 4x faster baud rate. So I define MY_BAUD_RATE 76800 and connect terminal with 19200, and it works. LGT is started in 8 MHz by default, and it looks like this is not corrected with mysensors. But this only helped for serial port, because later I had issues with DHT library timings.
If I later change speed to 16 MHz and start serial port again, it works as expected:
noInterrupts();
CLKPR = 0x80;
CLKPR = 0x01;
interrupts();
Serial.begin(19200);
Gawd bless ya @OldSurferDude , that just about answered every question I have to date, I especially thank you for indicating whether the item named is a software or hardware product.
On reading into the Cerbo GX capabilities I was very impressed with its sophistication and, just as you said, I will have to break the complicated parts down into bite-sized pieces and build from there.
It started with an idea for a project, essentially to take data on battery state of charge (SoC) from the Cerbo GX and use an Arduino Nano or ESP8266 to build a strategy so that I would have sufficient hot water in the morning, consistent with having enough battery power left in the evening. Only on further inspection did it occur that the Node Red software built into the Cerbo GX could do this for me...and thus the possibility that a wireless hot water temperature sensor (transducer) could be fabricated to feed that data into the Cerbo GX; hence my path to here.
I've dabbled in programming in C, mainly through the Arduino IDE, and in a previous life part of my work involved programming PLCs for industrial automation, so I am somewhat familiar with 'tech', but I lost interest once most systems seemed to go Windows based. In the intervening years the 'tech' has moved on apace and has left me behind, which is why I've struggled to follow the jargon, akin to trying to fit the second piece in a large jigsaw puzzle. Once the fundamentals are there I'll catch on.
So please, kind contributors, be tolerant of the silly questions we newbies ask, we won't always be newbies, and I'll be back for sensors stuff once I've tamed the red-hot node and sorted out my LBQTTs
Best wishes....MM
There are air quality monitors that can detect VOCs (volatile organic compounds), and some that claim to pick up marijuana smoke specifically. Devices like the Airthings Wave Plus, uHoo Air Sensor, or Plume Labs Flow could help identify changes in air quality. Another option is checking with industrial-grade smoke detection companies that provide sensors for businesses and schools, and some of them may also have solutions suited for home use.
