About

Raspberry pi pico W-based project to monitor electrical power consumption & basic environment data.

Power consumtion is collected over Modbus-RTU protocal from DTS6619 counter.

The data is sent into grafana cloud, using influx line protocol while the metrics end up as prometheus series.
Self-hosted grafanas will likely need this ingester installed and metrics sent into it.

Quickstart

git clone --recurse-submodules https://github.com/sashasimkin/pico-powermon

How to compile

https://docs.micropython.org/en/latest/develop/gettingstarted.html#compile-and-build-the-code

First run:

cd micropython/
make -C mpy-cross
cd ports/rp2
make BOARD=PICO_W submodules

In order to compile the whole project ready to flush & run:

make BOARD=PICO_W FROZEN_MANIFEST=../../../../manifest.py

In order to compile development version:
(It has dependencies only, the rest of the project should be uploaded to the flash storage)

make BOARD=PICO_W FROZEN_MANIFEST=../../../../manifest_basic.py

Installation

Upon first boot the hotspot PICO-POWERMON will be exposed.

Connect to it with the 0987654321 password.

Then open http://192.168.4.1:5000 in browser and configure your installment.
