ups-monitor

A mini project for observing and logging the input voltage for the APC-BR1500G ups installed.

The project's script.py however, works with any NUT compliant device.

Setup

The project is designed with a linux system in mind (and has been deployed to a raspberry pi device). The system published collected metrics to the thingspeak channel.

systemd units

There are systemd example units with the project, to setup the automated activity monitor. The units require defining certain environment values before they can be used effectively.

There is a .service and a .timer unit defined.

environment values

• THINGSPEAK_CHANNEL_ID: Channel id as given by thingspeak.com.
• THINGSPEAK_API_KEY: Your channel generated api key with write permissions.
• NUT_UPS_NAME: Name of the NUT compliant device. The device should have a input.voltage property.

python script

The python file script.py talks to the NUT server to fetch provided device's input.voltage variable and then forwards the same to the thingspeak channel (field1).

slack bot

You can use ThingHTTP service to trigger an HTTP call whenever there's a powercut or low voltage, or line fluctuations etc. and send it over to a lambda function. This lambda can then send a message over to slack channel informing about the same.

environment values

• SLACK_TOKEN: The token generated for your slack bot. Generally of the format xoxb-*
• SLACK_CHANNEL: Slack channel id where the message should be published.

Keep in mind that the message has not been configured to act as an embed. You can modify the message sent as per your requirements.
