Thank you .. sometimes it´s just my hope to get an easy solution running and waking up in the middle of to many micro learning.

Yes this works .. its in the tab "Privacy and Security" and there I had to switch from "Appstore and verified developer" to "Appstore" and then open the M5Burner again and confirm "Still open". Now it works on every start.

@mchott Speaking personally, I would have the Master also arbitrate the Slaves by polling them one at a time. Yes, they can all talk at once but it's messy. I have a Master talking to two Slaves ESP-NOW peer to peer with small size of data and no urgency in the process. I may send a simple boolean flag to one to turn on a heater, next sending a int value to the other to set a servo position. (this one also returns a float with the Vent Temp.

I don't think the PbHUB will work ... The PbHUB can only handle analog and digital signals (no clocks !). Reading values from the HX711 weight sensor needs a clock and a data line provided by the ESP32 GPIO Ports ... The UIFlow HX711 library only supports Port B. If you want to use several weight sensors on the M5Stack you will have to hook them up to different ports and do the programming either in Python or Arduino using the Expansion Port Module getting the additonal Ports C D and E. P.S: If you want to hook up multiple Weight Sensors to a M5Stack using port A you have to use HX711 devices which can be hooked up to the I2C bus. M5Stack has no such modules nor units, but you will find one made from DFRobot (https://wiki.dfrobot.com/HX711_Weight_Sensor_Kit_SKU_KIT0176). This sensor also has a grove I2C port and by modifying the I2C addresses you can hook up to 4 Weigh sensors to Port A. Using the PaHub I2C-extender you can even hook up 6 to 24 Weigh sensors ......

For me, the issue is resolved, but not quite with an eye to the future. I had the UI Flow IDE on the desktop 1.9.5 ( there is unfortunately not newer) and on the Atom Lite I had the 1.11.0. Thereby it came to incompatibilities that the EspNow in the newer variant works quite differently. BADLY.

I will try the " craft approach ". The LED driver does not provide stable 12V, as it can be between 12 to 14.5V in a camper. And with your recommendations for diode and capacitor.

Okay ... that falls then under "teaching money" and super stupid. Happens when it should always be done quickly on the side.

@mchott ESP_NOW in peer to peer mode. I wrote this simple bare-bones application to share with other makers. https://github.com/teastainGit/ESP_NOWpeer2peer I have a Core Basic communicating with two M5Stamps in the same room, controlling space heaters and an HVAC vent damper position. etc. The github example is used in all three devices

Hello @mchott in my experience a data SIM (for smartphones, LTE routers, etc.) is not good enough for NB-IoT. You will need a SIM card specifically for NB-IoT plus the NB-IoT service needs to be offered by the provider in your region. Thanks Felix

@felmue Super!!! The EEPROM seem to have some problems with integer values and fast timing. I store my integer now as string and wait until read is finished and it works.
