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)
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.
@OldSurferDude Thanks a very valued to know. I was wondering today why my (big) powerbanks fall down after short time. I have small 1 & 2-pieces powerbanks, they work very well. I use also BSM hw-168 or hw-107 for charging single 18650. Will try to use them outside also with small solarpanels.
@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!
