I think you need to post a clear drawing or photos of the setup and the code you are using.
I donlt know what you mean by "connecting the current in series" nor what "AC regulator" you are using or what "thermal serial currenr" is.
Hi @chey, no, with the pro minis and MySensors lib I couldn't get less.
Didn't measure with yet another multimeter though...
My battery sensors are working now for about a year and the battery levels are between 65% and 70%.
The sensor furthest from the gateway is at 65% and the 3 others at 70%.
Not bad I think.

@Michael-Link I have been out of touch with MySensors for some time now and looking to slowly get back into it. I created this and a few other boards back in 2018 All of the GERBER files for this are in the "Design Files" tab. Those you should be able to send to JLC PCB or one of the other fab houses and have some made. This was designed to be used with 2 other boards that I designed. There was the processor board and the power supply board. The processor board was designed in a way that I could use a couple different switch boards. This one and a universal multi-switch board that had multiple configurations. If you look here you will see my other boards.
Hello,
I'm thinking about upgrading this board to include pinout for LIS3DH breakout board, like this one :
https://www.aliexpress.com/item/LIS3DH-Three-Converters-Motion-Accelerometer-Triaxial-Acceleration-Temperature-Sensor-Module-Development-Board-Replace-ADXL345/32840326778.html
and ditch the ADXL shield as it's not a good solution, it has either the ADXL345 which uses too much power, or the ADXL362 which is ultra low power but lacks advanced functionality like tap/double tap detection.
I would like to have feedback of users on this (do it sound useful ?), and also know if anyone uses the SMD footprints on the board, for leds and for reserve capacitors, as it could be a cleaner board without those footprints.
I would make the following changes :
put footprint for LIS3DH accelerometer along the "NModule connector" as it has too many pins to put elsewhere
keep only one I2C footprint on the side, for "GY-49" MAX44009 light sensor breakout board: https://www.aliexpress.com/item/GY-49-MAX44009-Ambient-Light-Sensor-Module-for-Arduino-with-4P-Pin-Header-Module/32828654450.html
temperature/humidity would be via the existing "SMD" footprint, it's not through hole but very easy to solder as it's 2.54mm pad spacing
remove SMD footprints for LED, add footprint for through hole reserve capacitor, keep SMD footprints for reserve capacitors only if I have space for them
shield would be a bit extended to go over the 2 M2 holes in the "power" part of the NModule, so it could be fitted with spacers and nylon screws and have stable/reliable mechanical connection between NModule and Shield. Basically this would be the footprint of the shield :
So in the end it would make one shield to have Temperature/Humidity/Light/Acceleration or Temperature/Humidity/Light/Door.
