I have a few setups where I use multichannel relays to control 220V. It is always a pain to connect all the commons in serial. Does anyone know of a product that does this? Else I might just try my hand at a PCB to do this.
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?

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);
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...
@OldSurferDude Thanks!
I didn't touch the Arduino IDE for a while and forgot that the MYSBootloader doesn't come included in the Mysensor's library... My bad.
Thanks for the link! I should had searched first...
I use the OTA feature since 2017... It works well. So well that I forgot how to load the bootloader...
Regards!
