Raspberry Pi Power Supply Checker
<a href="https://liberapay.com/Toast/donate"><img alt="Donate using Liberapay" align="right" align="top" src="https://liberapay.com/assets/widgets/donate.svg"></a>
A sensor for Home Assistant that checks your power supply and reports back to your setup this simple sensor reports values from the kernel and if it reports anything else then 0 then there are issues with the power supply.
<h2>Breaking change: this project went from sensor to binary_sensor.</h2>- Manually download and install the files from the aforementioned URL into your custom_components\rpi_power
- Modify your config.yaml and make sure that - platform: rpi_power is under binary_sensor: section (create if missing) instead of sensor: (that's the breaking change the author is referring to in the readme)
- Restart Home Assistant
- Replace in your lovelace cards / automations / scripts / whatever... any mention to sensor.rpi_power_status by binary_sensor.rpi_power_status

Getting started
⚠️ This requires kernel 4.14 or higher.
Place the component at this location on your setup:
-
Home Assistant (former Hass.io):
/custom_components/rpi_power/binary_sensor.py -
Home Assistant Core / Hassbian / Other:
<config directory>/custom_components/rpi_power/binary_sensor.py_init_.py and manifest.json needs to be in the same folder
and then restart Home Assistant to make sure the component loads.
Here is a list of the current values the component checks for:
| Value | Description |
|---|---|
| 0 | Everything is working as intended |
| 1000* | Under-voltage was detected, consider getting a uninterruptible power supply for your Raspberry Pi. |
| 2000* | Your Raspberry Pi is limited due to a bad power supply, replace the power supply. |
| 3000* | Your Raspberry Pi is limited due to a bad power supply, replace the power supply. |
| 4000* | Your Raspberry Pi is throttled due to a bad power supply this can lead to corruption and instability, please replace your charger and cables. |
| 5000* | Your Raspberry Pi is throttled due to a bad power supply this can lead to corruption and instability, please replace your charger and cables. |
| 8000* | Your Raspberry Pi is overheating, consider getting a fan or heat sinks. |
Due to how custom_components are loaded, it is normal to see a ModuleNotFoundError error on first boot after adding this, to resolve it, restart Home Assistant.
