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.

Config

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

Adapter & CC Ease

In general it is not recommended to send data form 2 transmitters to one reciever in RS232 serial communication. The parallel use of CCEase and adapter can result in errors or, worst case, in damage to your comfoair-control! Therefore, when you start the ComfoAir - adapter your CC Ease will be shut down. The comfoair itself knows 4 different rs232-modes: CCEaseonly, PConly, PCMaster, PCLogmode. In PConly and PCMaster, CC-Ease is off. Once your adapter is running you can choose on of the following (adapter - rs232) modes, switching the control.rs232mode - object.

CC Ease only

CC Ease is running, but your adapter will niether get data from the comfoair nor send commands! (rs232mode is CCEaseonly)

Adapter only

CC Ease is shut down, you can control your comfoair only with ioBroker. (rs232mode ist PCMaster, is default & recommended)

Parallel Mode

CC Ease and adapter are running. comfoiar rs232mode is set to 'PCLogmode'. You can control your ComfoAir with ioBroker and with the CC Ease unit. Tests have shown errorless - running in parallel for a longer period of time. But: You run this mode on your own risk.

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. All values in the 'control' - channel have to be set wieth ACK=false to be recognized as commands for the adapter.

Tested on comfoair CA350.
