OneMeter-HomeAssistant Integration Setup helper

Instructions for setting up integration in Home AssistantOS to GET readings from OneMeter Cloud

Rest Integration with OneMeter Cloud

1. Add the below snippet to your configuration.yaml file: rest: !include rest-integrations.yaml
2. Download rest-integrations.yaml and change <your device ID> & <API key> inside the file to values from cloud.onemeter.com & . 2.1(Optional) Feel free to modify the file to your needs. Add/remove sensors modify settings etc. Currently, this integration has defined 7 sensors (all are extracted from OneMeter Cloud):
   sensor.onemeterfirmware - it will display firmware version of the OneMeter in v.0.23.0 format
   sensor.onemeterlastrefresh - this shows a DateTime of when HA sent
   last request to Cloud (this is calculated locally not based on cloud data, I used this for troubleshooting)
   sensor.onemeterlastread - this shows the DateTime of last successful read from OneMeterDevice
   sensor.onemeterbattery - this shows battery percentage
   sensor.onemeterenergy - this is what you need, this is a reading of your energy meter
   sensor.onemetercurrentmonth - this shows usage in the current month rounded to 2 decimal places
   sensor.onemeterpreviousmonth - this shows usage in the previous month rounded to 2 decimal places
3. Upload rest-integrations.yaml to the same folder as your configuration.yaml file in HA.
4. RESTART your Home Assistant instance (reload is not enough)
5. New sensors should be available in your HASS environment. Add them to your Dashboards if you'd like

Utility Meter in Energy Dashboard

After you have successfully setup the REST Integration we can move forward and add our Sensor to Energy Dashboard.

1. In Home Assistant: Go to Settings>Devices & services>Helpers
2. +Create Helper Utility meter (for more info on specific settings for this helper refer to Utility Meter Documentation
   Setup its name, and cycle and use sensor.onemeterenergy as input. Save your Helper
3. Go to Setting>Dashboards>Energy and in Grid consumption add your newly added Utility Meter Helper 5.(Optional). You can set pricing per kWh If you want to track that
4. Wait, as advised per HomeAssistant OS suggestion - After setting up a new device, it can take up to 2 hours for new data to arrive in your energy dashboard.

You should start to see the vertical bars in your Energy Dashboard ;)
