With my ORP sensors, I have to calibrate it every years (same for PH probe).
What is the best way to calibrate sensors with MySensors in you opinion ?
Use same child id (for sending data) ? Or another one ?

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)
@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
@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.
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!"

@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
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.
