node-red-contrib-ramp-thermostat

ramp-thermostat

A Node-RED contrib-node that emulates a thermostat.

The ramp-thermostat controls a heating-device such a valve depending on the actual input temperature and the target temperature.

The target temperature is defined by a profile that provides the value depending on the current time 00:00-24:00. The profile consists of several points whose connections build a sequence of lines. The switching moment can be optimized by defing a gradient line like a ramp.

The node provides 3 outputs:

• state (boolean)
• actual temperature
• target temperature

Installation

Change directory to your node red installation:

$ npm install node-red-contrib-ramp-thermostat

Configuration

Define a profile which consists of up to 10 Points. A Profile has at least 2 Points. The first Point must start at 00:00 and the last at 24:00. The target temperature is calculated depending on the actual time.
