NuHeat Signature Integration

Developers
1

NuHeat Signature provides integration of NuHeat floor thermostats with Hubitat.

This is a new integration based on the latest OAuth2 API for NuHeat.

The integration consists of a connection application, and a device that presents itself to Hubitat as a thermostat device.

This integration supports multiple NuHeat thermostats per installation. The connect app automatically creates the devices it discovers.

The nuHeat Signature thermostat should be already configured and operating properly with the nuHeat website and mobile app prior to enabling this integration. This integration does rely on the nuHeat cloud/APIs.

You do need to request OAuth2 information from NuHeat, see the GitHub link below to see the instructions for this.

Current Release Updated October 18, 2026

First device release May 17, 2020

Installation and Updating

  • This is available via HPM

  • Or you can install the connect application and device driver by hand

GitHub:

reserved for future use

Thanks for posting the integration! I installed the driver and can access my NuHeat thermostats - I'd like them to go into standby mode based on a Rulemachine condition (away-mode) but I have not been able to figure out how. Is that possible with your integration?

4

There is a command indefinite hold to look at.

5

Thanks - I am able to get it into indefinite hold now, but I don't seem to be able to resume. Do you mind letting me know what the parameter/value is to accomplish this?

6

Never mind- figured it out!

Thanks for porting this. Have a question/comment. In command "setHeatingSetpointWithHoldTime" it brings up a date picker, based on the Nuheat phone app hold times are based on hours with a max of 23 hours. Is there something I'm missing

8

Updated posted. New command added to setHeatingSetpointwithHoldHours

many optimizations

This is working very well. Thank you for creating this for Hubitat.

One request: could you add:
capability "Thermostat"
on about line 42?

This will allow InfluxDB Logger to recognize the NuHeat Signature as a Thermostat and pass attributes such as heatingSetpoint to InfluxDB.

Thermostat draws in a lot of commands (that need to be created and nulled out).

can influxes just check for heating or cooling or temperature?

11

I just checked her code and it looks like it'd be a heavier lift. Adding that one line in yours did the trick for me but maybe there are unintended consequences that I don't understand. In any case, I was hoping it was an easy fix but it sounds like not. I do now also see that you had this commented out on line 36 so I'm just uncommenting it at the moment so the InfluxDB Logger sees the NuHeat Thermostat as a Thermostat and passes the attributes over to the DB.

If there are unintended consequences of that that I should look out for, I'm all ears. Thanks anyway!

Is anyone aware of an IP-only version for this device that will not require it to be connected to the actual internet? Just the home network by IP address?

13

I don't think Nuheat does this.

14

What template do I choose on my Dashboard?

15

OJ Microline makes a similar thermostat with essentially the same properties, perhaps even mostly the same parts. I wonder if this integration can be adapted to enable control of those thermostats? ojelectronics.com/UWG4

Many have noticed that this original nuheat integration has stopped working due to authentication changes in NuHeat's apis.

I have a new integration that is based on a connect application model (as the new integration api work on oauth2)

I plan to post this updated integration, and wanted to give folks a heads if they did not notice, the old integration is not working...

19

You may need to HPM repair, or uninstall the previous device before installing the new connect app.

The GitHub link has information on how to request the OAuth2 information from Nuheat.

Working for me. It took 1 day to get the token. What a clunky way to run a business.

A couple suggestions: move the app from Apps to Integrations and put a link to the auth instructions in the app.

Thanks for your work.
