Hi all
I am new to all this stuff so hope you can help, I am looking for a Proximity sensor that is 12V and water proof but struggling to find anything that would match what I need can anyone help or point me in the right direction please

1: 12V for a car or truck
2: needs to be water proof
3: able to adjust the distance accordingly to where we need it
4: when within the correct distance of activation it will need to turn a LED light on or similar

Once I have found the correct sensor I should be able to make up a circuit but it's finding it

@andriej 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)

Thanks for the offer @TheoL ! I have moved on to a differenct project. Also, a lesson that I have learned many times, "If it works, don't fix it!" -OSD

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.

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.

@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! Regards, Gunnar
