KC868-a8v3 IFTTT for Aircon use - beegeenz - 03-12-2026
I have KC868-a8v3.1 board loaded with the current firmware V3.23.2
It is used for switching 24VAC to control AC ducts in conjunction with Home Assistant.
My challenge is that the Rumpus room duct (controlled by DO8 on KC868) is fed from a master upstairs duct (controller by DO2 on KC868) so both ducts need to be open for AC to reach the Rumpus room.
For ease of user operation I would like to setup the a IFTTT rule so that;
1. when a user turns on the Rumpus duct (D08) the upstairs duct will also activate (D02) (turn on could by by HA or RF on the KC868)
2. if the user subsequently turns off the Rumpus duct, the Upstairs duct will remain open.
Also, if the Upstairs duct is turned off, there should be a rule to turn on the Rumpus room duct, this is necessary to reflect through to the HA dashboard.
Using IFTTT I setup an IF condition on the DO8 which performs an action on D02.
I found that this doesn't work properly and the KC web page status indicator for D02 and D08 are not linked corectly by the rule. At one stage the KC868 crashed and I had to relead the formward with the formward loader tool.
Can you please advise if IFTTT can be used for this sort of rules or is there another way on the KC868 to achieve this.
Regards
