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)
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.
LiFePO4 batteries are a great choice because they have a long life cycle and are much safer than other lithium-based batteries. However, you need a solar charge controller that’s compatible with LiFePO4 to prevent overcharging and maintain efficiency. A good MPPT controller can significantly boost energy harvest from your panels. Also, ensure your solar panel output matches your power needs. If you're in solar ireland, you might find some local companies that offer tailored solutions for maximizing solar efficiency in lower light conditions.
@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
