Hi, I had problem using the main branch mysensors/Raspberry, that because of the bit-field struct (header_s) in Sensor.h They will get packed in different order on the arduino compared to the RPi (at least with my compiler, gcc). In order to fix this I created the 1.4dev branch. It uses full bytes instead of the bit-fields, but you need (of cause) to compile both the sensors (arduino) and the gateway (RPi) using the 1.4dev branch.
We need to fix this in the main branch later on (and use the same files as in mysensors/Arduino/libraries/MySensors)
@eiten Ran into the same error but of course the community is always at hand, ready to help! Great! I'm using MySensors 2.3.2 release version. Downgrading the ESP8266 board library to 2.7.4 as suggested by @OldSurferDude did the trick.
I'm still clinging to MySensors. So simple and inexpensive to use! All sensors and other stuff connects over three MQTT GW in three locations back to my Home Assistant.
PS: Get well soon!

For me almost all I need is in Master. For some nice to haves I have some custom libraries, like a message and a presentation queue. The only wish I have is dual led support.
Nice work so far @wint0178, great that you try expanding on the examples. Sorry for the late reply.
If you look at https://github.com/mysensors/MySensorsArduinoExamples/blob/bba998bce09bc5139eb4ca7a05b0279f4083ff88/examples/PressureSensor/PressureSensor.ino#L90 you see where the existing child ids are defines. You just add another one for the gas sensor, with a unique number (incrementing by 1 is an easy way).
Try that and report back on your result. If something is unclear, just post a followup.
AI-based radar nodes sound like an exciting advancement, especially for security and smart home automation. The ability to detect human presence without movement could be useful for elderly care, energy efficiency, and security systems. Using a serial protocol makes integration straightforward, making it a feasible weekend project for those familiar with microcontrollers. However, privacy concerns are valid—just like with any smart home technology, balancing convenience with data security is key.
@Shirkit I agree. I have a lot of unifinished projects. Most of them still on breadboards. But as we will do a big reno on the house I need to finish them. Pretty sure I wouldn't be able to figure out how they worked if I store them in boxes during the reno. I have some light projects, A garden controller just an improved version of what was posted many years ago. And some more generic things that are probably not interesting to most people. And I also have a hub node the allows you to use cheap rf modules from AliExpress to control rooms very easy. I transformed a for channel remote module to a 15 button remote.
Without this site I wouldn't be able to keep making MySensors stuff
