+--- Thread: H32B conrolled by Nodered (/showthread.php?tid=7272)
H32B conrolled by Nodered - Saif Kitany - 12-27-2024
hello technical support team,
I produced nodered diagram(for test) to control h32b controller. for test, i want to control 3 realys by one switch.
the problem is :
when i turn on the switch, i got just one relay turn on from the three relays.(they don't turn on all of them in the same time). but if i put timer for the other 2 relays, then i got all relays turn on.
realy 22----> 0 sec
relay 23---> 0.3 sec
relay 24---> 0.6 sec
i will add a pictures of the diagrams : one picture without delay, the seconed picture with delay

if you are using KC868-H32B, you can set auto off time for every relay in config webpage, not need use by node-red. that control by CPU directly.

But i don’t want to set auto off time.
My purpose is to create some scenes, like turning on some relays together by nodered.
Or for example turning on light for 2 minutes when opening car gate .
How can i do it?

let H32B digital input and relay output integrate to Node-red by MQTT.
here is video tour: https://youtu.be/841Hv7iPdk8

ok, got it.
Now I'm having a problem. I chaned the mode in the ethernet mode from UDP to mqtt and inserted the username and password, and saved.
there were some relays in the H32B that i set time auto off, and after changing the UDP to mqtt, I noticed that the time auto off reset to defult and now thers are no auto off relays. and also i'm not able to enter the settings by the ethernet IP address which was 10.0.0.3
what should i do?
RE: H32B conrolled by Nodered - admin - 12-29-2024
1. Hold on Ethernet button on PCB, when the [yellow and white LED] all is ON, release it, then work mode in “UDP” and IP by DHCP mode;
2. use kincony scan device tool to find out controller IP address.
3. login by webpage, check what firmware version you are using? you can try to update to newest version V5.08 for KC868-H32B controller, here is download link: https://www.kincony.com/forum/showthread.php?tid=3323

Ok, i did it and succeeded to access H32B setup.
My H32B version is v4.41. (It’s old chip and need jlink to download load v5.08).
Question1 : why when I set mqtt mode, I lost access to H32B setup?
Question2 : why the auto off relays settings got reset to default when set mqtt mode?
Question3: is setting mqtt mode in v4.41 makes problems?
Question4: if I download v5.08 using jlink, and then i set ethernet in mqtt mode, how then i can access H32B setup?

mqtt need time to connect to broker. Can you take a video of all progress.
i think you can download some different firmware BIN file to test, just BIN file size <128k can use by old chip.
