NuHeat


The nuheat integration lets control your connected NuHeat Signature floor heating thermostats from NuHeat.

There is currently support for the following device types within Home Assistant:

  • Climate

Prerequisites

First, you will need to obtain your thermostat’s numeric serial number or ID by logging into MyNuHeat.com and selecting your thermostat(s).

Configuration

Adding NuHeat to your Home Assistant instance can be done via the user interface, by taking the following steps:

  • Browse to your Home Assistant instance.
  • In the sidebar click on Configuration.
  • From the configuration menu select: Integrations.

NuHeat can be auto-discovered by Home Assistant. If an instance was found, it will be shown in the top of the list of integrations as “Discovered”. If that is the case click on the Configure button to start setting up the discovered instance.

If there wasn’t any discovered automatically, don’t worry! You can set up a manual integration entry:

  • In the bottom right, click on the Add Integration button.
  • From the list, search and select “NuHeat”.
  • Follow the instruction on screen to complete the set up.

After completing, the NuHeat integration will be immediately available for use.

Concepts

The NuHeat Thermostat supports the following key concepts.

The target temperature is the temperature that the device attempts to achieve. The target temperature is either determined by the schedule programmed into the thermostat (auto mode) or may be overridden. When the target temperature is set by Home Assistant, the thermostat will hold this temperature until the schedule is resumed.

Services

The following services are provided by the NuHeat Thermostat: set_temperature, set_hvac_mode, set_preset_mode.

Service climate.set_hvac_mode (Climate integration)

NuHeat Thermostats do not have an off concept. Setting the temperature to min_temp and changing the mode to heat will cause the device to enter a Permanent Hold preset and will stop the thermostat from turning on unless you happen to live in a freezing climate.

Service climate.set_temperature (Climate integration)

If the thermostat is in auto mode, it puts the thermostat into a temporary hold at the given temperature.

If the thermostat is in heat mode, it puts the thermostat into a permanent hold at the given temperature.

Service climate.set_preset_mode (Climate integration)

The following presets are available: Run Schedule, Temporary Hold, Permanent Hold.
