ioBroker.comfoair

An ioBroker adapter for Zehnder Comfoair 'CA' -ventilations (i.e. ComfoAir CA350, NOT ComfoAir Q350...)

To use this adapter, you need a RS232 to LAN oder WiFi Converter to connect ioBroker with your Zehnder Comfoair. Install hardware for TCP - connection to comfoair: i.e. RS232 to LAN adapter to the serial interface of the comfoair. Connect Pins 2, 3 and 5 only (should work also with TX, RX and GND - contacts of the cc-Ease connection too). Actually this adapter works only with a LAN-Connection. A direct link based on a direct serial connection is in development.

Install adapter, create instance.

CCEase and use of the RS232-interface

The comfoair knows 5 different RS232 modes: End/without connection, PC only, CCEase only, PC Master, PC logmode. Default is CCEase only. The parallel use of CCEase and RS232 results in errors! It is higly recommended to disconnect the CCEase cotrol panel while you're using this adapter or to switch in PC Master mode, what will disabel CCEase too. A hardware based solution for a data - traffic - switch is in evaluation, support is welcome.

Config

Set comfoair - IP-adress, port and polling - intervall.

RS-232 Manual Mode

In this mode you get a rs232mode object in the 'control' and in the 'state' - channel. In the 'control' - channel you can set the RS232 - mode PCMaster and PCLogmode. In PCMaster mode, your CCEase's display will be off an there is no data traffic between the comfoair and the CCEase. To swicht back to CCEase only mode you have to 'hard-reset' your comfoair (power off - power on).

Using the adapter

Values of your comfoair should be visible in the 'status' and the 'temperatures' channel.

By setting/changeing values in the 'control' - channel, you control your comfoair ventilation.

Tested on comfoair CA350.
