I have a problem that I can't solve. This is already my second board because I have a well-functioning A64 version, and now I'm trying to use the A128 version.
I'll start by saying that enabling MQTT (protocol->general->mqtt) is only possible for me on version v1.0.27. In firmware versions > v2 with IFTTT, it doesn't work—when I enable MQTT, the controller freezes, I can't access the web panel, and only a factory reset helps.
Only in version v1.0.27 does the controller not freeze after enabling MQTT. But here, I have another issue. When MQTT is enabled and I set any input to perform an action, after executing the action, the controller temporarily loses connection with the MQTT broker and then reconnects after a few seconds—I can't smoothly control the lights.
As I mentioned, I also have the A64 version, which runs on the same broker with firmware version 2.2.2, and everything works fine there. I have no more ideas on what could be wrong. I've checked the broker configuration, tried different settings, and nothing helps. I've also connected to external brokers, and the issue persists. I have flashed all your firmware versions onto the controller, and I can't get MQTT to work on any of them except for v1.0.27.

i think you can use our new KCS v2 version, here is download link: https://www.kincony.com/forum/showthread.php?tid=7283

As I wrote, any other software crashes the controller after enabling MQTT – the controller is visible on the network, but the web panel does not work. Only a factory reset helps. I have install all your available software versions, and the same issue occurs on each of them. Only on version v1.0.27 does enabling MQTT not crash the controller - but in this version, MQTT disconnects when performing an input action.

we will test it, then feedback to you.

on versions:

2.2.10
2.2.2
2.2.6
2.2.8

Every time I try to enable the MQTT option, the controller resets and never comes back online. It becomes invisible on the network, and only a factory reset helps.

I connected to Kincony via USB port and am checking the logs through PuTTY. After uploading firmware version 2.2.10 or newer and enabling MQTT, errors start to appear constantly. Below is a snippet of the logs:

edit: I tried changing the power supply. It doesn't matter whether I try with 12V or 24V (around 3A), the problem is the same.

and here logs from version 1.0.27. As I sed, in this version, the controller doesn't freeze when the MQTT option is enabled – the web panel works. But when I trigger the input action assigned to the output, the controller freezes for a few seconds. In the logs, you can see it performing the input action, and then a connection error with MQTT appears.

My network is very simple, all devices are connected to the same switch, there is no routing, no port blocking. Besides this board, I also have an A64 version, which is plugged into the same switch and works correctly with any software, connecting to the MQTT broker on the same address. I also changed the Ethernet cable to a different one, but it makes no difference.
