Looks as though the raspberry pi pico will provide 16-bit PWM duty-cycle resolution

Contrast that 65535 step resolution to the 255 step duty-cycle resolution on Arduino's, and that is a big improvement for control of, say, a DIY DC-DC converter. For instance, if you want to build your own DIY solar MPPT boost converter (good luck finding one to buy in the commercial market. Probably 99%+ of those are step-down MPPT controllers, with only a rare bird being a step-up MPPT controller). The pi pico's are just $4 each at mouser and Adaruit ( https://www.adafruit.com/product/4864 ) for the genuine article, not some sketchy knock-off. Just thought I'd mention it, as I think most people aren't aware of it. I'm not sure whether or not a more stripped down version of the pi pico would consume significantly less current. If so, then it might be quite compelling: a fully formed pi pico board for $4 vs. an atmega328p chip alone for $3 (note: as a reference, these are present market prices on mouser).

@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)
No merge into master in the last 5 years, should we use development?

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.

I hope the project won't be buried due to the fact that the protocol is the basis of nippy devices (https://nippysmart.com/) I also hope that the development of mysensors won't be directed in 2 directions - one commercial only for nippy - the other for all the rest, which could result in the two versions diverging so much that they will be incompatible and the second one will simply be buried.

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.

@GLAB You can set the frequencies using the settings in MyConfig.h, which is in the MySensors folder. If you put any of the defines from MyConfig.h into your sketch, they will override the MyConfig.h setting for that sketch only. If you are using the RF24 radio, there are different channels which correspond to a given frequency. The default is channel 76. There is a list of typical channels in MyConfig.h. If you want to change the channel for all the sketches, change it in MyConfig.h. If you want to change it just for the sketch, add a define to the sketch. For example: #define MY_RF24_CHANNEL (84) The problem with changing the channel in a sketch is that the gateway has to be on the same channel to receive from the node. So, normally it makes sense to change in MyConfig.h because you usually want the gateway and all the nodes on the same channel. Other radio's like the RFM69 list the frequency instead of using a channel. They can be overridden in the sketch as well. You can find the defines that are needed in MyConfig.h
