Monitor 1 shows power=0 while Monitor 2 shows correct values

Posted by: tombueng - 03-15-2026, 03:48 PM - Forum: N20 - Replies (1)

My Monitor 1 shows Power=0 for all channels even if there is current which is wrong.
Monitor 2 shows values correctly.

Voltage / Freq 226V, 50Hz is shown on both inputs (both connect to the same phase)

Protocol -> Energy has the same values for Energy 1 and 2 for all of the values of Current Factor=0.5, Power Factor=1, Energy Factor=1

Firmware v3.22.0

What might be the Problem?

Is there no OTA-Update available? Do I need to connect a via USB PC to Update the Firmware?

F8 on device physical switches in ESPHome

Posted by: Vinceken - 03-14-2026, 08:07 PM - Forum: F8 - Replies (1)

	Hi - with esp-idf in ESPHome, how can I access the state of the physical on device switches? I can't seem to observe those on any GPIO pins. I would like to configure (in esphome) some of them to control their output relay directly, but for others for them to act as momentary switches. I can manage all the coding myself if I can work out where to observe their state... Thanks.

Adding a debounce capability to inputs

Posted by: twostar - 03-14-2026, 02:09 PM - Forum: KC868-A16v3 - Replies (4)

At the moment the KC868 inputs are instantaneous which is a problem for signals that glitch occasionally from things like noise coupled onto the input lines. Would it be possible to add a debounce capability where you can specify that an input has to be asserted for x seconds, x user-settable, before it gets reported as an asserted input? What I'm thinking of is adding a per-input capability where you can specify that it needs to be asserted for (say) 5 seconds before it's treated as valid. The overall range would be maybe 0-60s, 0s = instant response, > 0s = input must be asserted for that long before it's reported as asserted.

KC868-a8v3 IFTTT for Aircon use

Posted by: beegeenz - 03-12-2026, 10:59 AM - Forum: KC868-A2v3 - Replies (1)

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
