Add-on: Climate

Description

This add-on enables the use of your panel's relays to act as a thermostat (either cooler or heater) using the internal temperature sensor and independent of the network availability.

Attention

The NSPanel is limited to 2A per relay. Don't use it for directly power your cooler/heater if exceeding the panel specifications:
- 150W/110V/Gang, 300W/110V/Total
- 300W/220V/Gang, 600W/220V/Total
A target temperature must be set on the climate entity in Home Assistant or the page Climate in your panel.

Note

More details on the Sonoff NSPanel's page and the product specifications document.

Installation

You will need to add the reference to addon_climate_heat, addon_climate_cool or addon_climate_dual files on your ESPHome settings in the package section and after the remote_package (base code), as shown bellow (for heat in this example):

Note

From time to time, there are changes in ESPHome that lead to an added _2 for the embedded thermostats. If you encounter this issue, please have a look at this entry in the Home Assistent Forum.

Concrete example: (Water) underfloor heating

The NSPanel is particularly nice as a replacement for existing water underfloor heating controllers. They are installed at approximately eye level and (often) supplied by 230V. In my case, the valve is type 'normally closed,' i.e. an open relay corresponds to 'no heating.' I am using relay #1. Please note that this is not a PID controller, but simply on-off. At a certain value, the heating starts and at another value it switches off again. These value were set to 0.3°C below and 0.1°C above the setpoint, respectively. It turned out that 0.3and 0.1 worked well for all off our 4 rooms. The minimum settable value is 15°C, the maximum 22°C and the granularity (step size) is 0.1°C. In addition, I chose to set the default temperature to 21.2°C.

Please note, that any filter that smoothes the temperature readings (e.g. averaging) is discouraged since it slows the response times of the already slow underwater floor heater. The temperature stability is quite nice which can be seen in the following viewgraph.

Mar 5 at approx. 9.30am, the window was opened and all heaters were set to 'off.'
