@OldSurferDude maybe some water flows past the meter before it starts turning?

Nice work @Kokosnoot
I think you could use

#define MY_RFM69_IRQ_PIN 2
#define MY_RFM69_IRQ_NUM digitalPinToInterrupt(MY_RFM69_IRQ_PIN)

This should convert the pin number to interrupt number automatically.

@KevinT should be one of these https://github.com/mysensors/MySensors/pulls?q=is%3Apr+esp8266+sort%3Aupdated-desc+

@KevinT did you read the thread I linked?

Great to see you again @KevinT

It is broken, and you are doing something wrong :-)

Use the latest supported version of the board definitions. See https://forum.mysensors.org/post/114086

Sorry, I have no idea.

Welcome to the forum!

Tagging @sundberg84 who created this pcb.

Thanks for reporting @Honk

@hek has fixed the cert issue now

It is the receiver's eeprom that needs to be cleared. In most MySensors networks, the receiver is the gateway. But since MySensors supports node to node communication (for example a button node sending a message to a relay node), any node can be a receiver. So in the example, the eeprom of the relay node would also need to be cleared.

I have not used signing myself, but I think you’ll need to wipe eeprom of all nodes.

See https://www.mysensors.org/apidocs/group__SigningSettingGrpPub.html#gaf44407e0f498eca7069adf5e59ffe052

Nice work @Aymeric, thanks for reporting back!

@Aymeric are you sure the node isn’t sleeping for 5 seconds? WUP=-1 means it woke up by timer.

Check using an external clock, and/or turn on timestamps on the Arduino IDE log.

Nice work @Branther

The disadvantage is that the node won’t be performing all the stuff that normal nodes do. But since you don’t want that stuff for this particular node, there is no real disadvantage.

Hi Branther. Great to see you back!

These topic give some info on what can be done:
https://forum.mysensors.org/topic/9879/setup-for-the-fastest-sensor-startup-time/
https://forum.mysensors.org/topic/8827/serial-gateway-nrf24-with-sleep-mode-enabled-there/

Check if these help, and post any follow-up questions you might have.

I read an interesting take on AI and IoT today: https://tinkeriot.com/esp32-mcp-llm-ai-integration/

I don’t have time to tinker these days, but mcp looks like a nive way to interact with IoT sensors. I wonder how hard it would be to build a mcp for MySensors and if it would make sense.

With the amount of spammers, it would need some sort of moderation. Otherwise it would just be filled with spam and affiliate links.

But a lot of people have earned reputation on the forum, so that could probably be used to give access.

11.3mA according to the datasheet

But 13.5mA when in receive mode.

The bew error you got is discussed in https://forum.mysensors.org/topic/11448/config-h-39-first-defined-here/4

Easiest way is probably to switch to the development branch of mysensors.

Run git checkout development and then start over from the configure step. Or follow the step ”To use the development version with the latest updates” on the raspberry pi gateway build page.

The key is here:

hal/architecture/Linux/drivers/core/interrupt.cpp:33:10: fatal error: stropts.h: No such file or directory
33 | #include <stropts.h>
| ^~~~~~~~~~~
compilation terminated.
make: *** [Makefile:99: build/hal/architecture/Linux/drivers/core/interrupt.o] Error 1

See https://forum.mysensors.org/topic/11138/mysensors-build-problem-on-ubuntu-20-04-rpi-or-tinker-board/2 for a possible workaround. Then restart from the make step.

Mysgw will only be created after successful make.

Nice work @goblin

Could you share all commands you ran and the entire output, including the configure, build and test steps?

Also, I don’t think Domoticz can use the gateway as a client. You should probably omit the --my-controller-ip-address=127.0.0.1 argument.
