Hi dear, I wish to know if there is a way to backup settings when upgrading firmware version and restore after the new firmware installed. Thanks in advance

My H32b pro not connected with my local network kindly help to solve the issue.

Dear Support,

could you please post the schemtaic of the 1.6 boards? I am confused with the pins 32,33, 36, 39 and their relation to S1,2,3,4 which seems to be different in v1.5. I am looking for a pin direct connected to the esp32 - without pull-up/down.

I tried to connect an AM312 to one of the pins S1-4 but it does only work with an external pull-down of 4.7k. This sensor ouputs digital 3.3V as HIGH and should be connected direct to a pin without pullup or down.

Thanks,
Tom

Trying to flash KC868-a16, the flash worked fine the first few days but now its giving error!

I've identified an issue with my M16 board whereby the SH31 sensor becomes disconnected after the setup() function and can no longer be read.  I've tried a number of variations on the bus settings, but there seems to be no effect.  The relevant setup() code is this:

I've made available via GitHub project a C++ project for the M16 board.  This application will read CT sensors on the Kincony KC868_M16v2 board and calculate power usage. It allows per sensor configuration and sensor correction algorithms. Periodic MQTT messages are emitted with various readings and configurations can be set via MQTT messages and saved into non-volatile memory.   It also includes an STL to allow you to print a rudimentary cover for the board which will allow it to be surface mounted via screws.

The code is too large to post here, along with the numerous class files, so I'd direct you to Github:  https://github.com/LouPaloma/KinconyM16-PUBLIC

The code is marked with a number of TODO/FIXME, so patches and pull requests are welcome, although I have limited ability to test since my own unit has been "deployed".

(Also, I have identified an issue with the SHT31 sensor, but I will open a separate thread for that.)

Good afternoon,

I want to control 2 different devices fans with 0-10v capabilities of one KC868-A4S but I'm not sure about wiring.

For the first fan from AFL Motors (file 122) these are the connections that I plan :
 - 0-10 VDC yellow on fan with AO1 on KC868-A4S
 - GND blue on fan with GND after AO1 on KC868-A4S

for the second fan from Aermec (file 22) these are the connections that I plan :
 - 0-10V IN V2 blue on Aermec with AO2 on KC868-A4S
 - 0V V1 grey on Aermec with GND after AO1 on KC868-A4S

Am I right or wrong ? If I'm wrong, what are the right connections ?

Thanks

Hello,
In a previous email I mentioned that I am using the SIM 7600 module with the ESP32 S3 WROOM 1U, however I can't use the serial monitor in order to receive information (I can't see data), I would like to know if you have any advice for the ESP32 S3 set up in Arduino firmware. See my below set up in tools menu:



I followed you recommendation with ''USB CDC On Boot'' = ENABLE, and now I have below information in the Serial Monitor:

I think I need to change something else in the Tool config but I'm not sure.

Thanks.

Hi!
I purchased some KC868-A8 to install in my new home and I'm now testing them. 

I flashed one with ESPHome but the switches don't change relay state unless I program an automation in Home Assistant to do that (if input1 on/off change alternate relay state). Is it there anyway to configure this without HA? Should I use another firmware for this?

I also like to know if there any other device that can work with dimmable leds.
