node-red-contrib-comfoair

Node-RED Node, that reads and parses the data from a Zehnder ComfoAir 350 and similar devices.

This work depends on the comfoair Module (node-comfoair@github and comfoair@npm).

Install

Just run

    npm install node-red-contrib-comfoair

How to use

Connect to your bus system via serial connection and configure the comfoair node. Follow the instruction for streaming with comfoair and pass json objects to this node.

Additional info from VincentSC

Zehnder talks about intake, exhaust, supply and extract. Or extract, supply, incoming and outgoing.

This library uses supply, exhaust, outgoing and outside.

This is my guess how it translates:

• outside = intake / incoming
• supply = supply
• exhaust = extract
• outgoing = exhaust / outgoing
