Solyx Energy Cloud

The Solyx Energy Cloud integrationIntegrations connect and integrate Home Assistant with your devices, services, and more. [Learn more] is used to integrate with Nymo devices from Solyx Energy. The Nymo controls an electric boiler with exactly the amount of solar energy that would otherwise be fed back into the grid. It allows households to store their surplus solar power and minimize feed-in, without huge investments.

Prerequisites

1. Open the app store on your Android or iOS device, and install the Solyx Energy app.
2. Create an account.
3. Add a new device to the app, and follow the instructions to set up your Nymo.
4. Once finished, go to the home screen and select the Nymo you have added. Go to the Settings tab.
5. Scroll down to the Connect your Home Assistant section, and press Connect.
6. Copy the Client ID and Client Secret, and use them when adding the integration in Home Assistant.

Sensors

• Boiler current

  • Description: Measures the electrical current drawn by the boiler in amperes (A).

• Boiler power

  • Description: Measures the boiler’s electrical power consumption in watts (W).

• Boiler voltage

  • Description: Measures the electrical voltage supplied to the boiler in volts (V).

• Days since maximum temperature

  • Description: Shows how many days have passed since the boiler last reached its maximum temperature.

• Grid power

  • Description: Measures the power exchanged with the electrical grid in watts (W). This can be a positive or negative value.

• Days since last legionella prevention

  • Description: Number of days since the boiler last ran its legionella prevention cycle, in days (d).

• Saved today

• Saved this week

  • Description: Shows the amount of energy saved during the current week, in kilowatt-hours (kWh).

• Saved this month

  • Description: Shows the amount of energy saved during the current month, in kilowatt-hours (kWh).

Data updates

The Solyx Energy Cloud integration polls data from the device every minute. Since it uses a cloud connection, an internet connection is required for the integration to work.

Known limitations

The integration uses a cloud connection; therefore, full local control is not possible.

Troubleshooting

Can’t set up the device

Authentication error

Verify that you have copied the correct credentials from the Solyx Energy app. To re-authenticate, remove the integration and set it up again.

Couldn’t retrieve device data due to a communication error

A communication error may appear when configuring the device. This is often caused by no data being available to be retrieved or sent by Home Assistant. If the device has been set up very recently (less than 30 minutes ago), it might help to wait and try again.

Device data is not updating

If the data in the Solyx Energy app does not correspond with the Home Assistant data, check your internet connection. Be aware that a cloud connection is required, and data is only updated once per minute.

Removing the integration

This integration follows standard integration removal.

To remove an integration instance from Home Assistant

1. Go to Settings > Devices & services and select the integration card.
2. Next to the entry you want to remove, select the three dots menu. Then, select Delete.
   • Depending on the integration, the entries are listed under one of the following headings:
     • Devices
     • Hubs
     • Services
     • Integration entries
3. To confirm, select Delete.
   • Home Assistant also deletes the devices and entities of the entry.
4. If Home Assistant asks you to restart, restart Home Assistant.
5. If Home Assistant asks whether to also delete the application credentials, select Remove or Keep.
   • If you keep them, Home Assistant uses them automatically when you add the integration again.
   • To delete them later, refer to Deleting application credentials.
