# Monitoring

This is the sub project to establish monitoring for various things, that cannot be implemented in the Kubernetes cluster. This goes mostly into the direction of client side MQTT messages from sensors.

## setup

### esphome

Setup is based on [this guide](https://esphome.io/guides/getting_started_command_line.html).

```sh
brew install esphome

# wizard to create new devices
esphome wizard muc-kitchen.secret.yml

# flash to device
# -hold boot button to enable flashing on esps
esphome run ./config/muc-kitchen.secret.yml
esphome run ./config/muc-living.secret.yml
```

### custom firmware for hygrometers

To flash a custom firmware for this sensor.

* Android handy, go to [this page](https://pvvx.github.io/ATC_MiThermometer/TelinkMiFlasher.html).
* Flash firmware.

To test everything, check this YouTube Video and use the app "nRF Connect for mobile".



### dyndns-muc

See file `dyndns-muc.moritzgraf.secret`.

TODO: Not sure why the respective update URL does not work.

### prometheus

Metrics are provided on `/metrics` link see in config file.

## no longer relevant

Switched from MQTT to prometheus exporter setup.

### MQTT testing

To test MQTT a cli can be used. See [hivemq install instructions](https://hivemq.github.io/mqtt-cli/docs/installation/#homebrew).

```sh
mqtt sub -h moritzgraf.de -p 30024 --user sender -pw <password> -t demo
############# general mqtt
# get nodeport of mosquitto
kubectl get svc mosquitto -n datalab
# for password see `cat ../k8s/datalab/mosquitto.secret.yml`
# subscribe to topic
❯ mqtt sub -h moritzgraf.de -p 30024 --user sender -pw <password> -t demo
# publish a msg in different shell
❯ mqtt pub -h moritzgraf.de -p 30024 --user sender -pw <password> -m "HEllo" -t demo
```

#### paho

```sh
pip install paho-mqtt
python publish.py
```
