I ran into this article that uses MySensors and the nrf-doctor to correct issues with Pcb antennas on nRF24 modules.
I didn't try it, but seems to deserve a mention at this forum!

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)
@CodeGarage What I want is a lion powered Sensor if possible. And that in a case I can stick to the door frame. As I cannot screw or drill into the doorframe. But I have no idea how much current that draws.
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.
Old topic, I know. Did anything ever come of this?
I'm also thinking it would be easy & cheap to get the espnow working as a transport layer.
I found this: https://www.mysensors.org/apidocs-beta/classESPNOW.html
But it goes above my head and abilities when it comes to code.
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.
