How should i connect F16 to PC? Always got appear and disappear usb port shown. What should i do? Thanks

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'm trying to install a Wika A-10 Pressure Sensor/Transmitter 8-30VDC 4-20mA P# 13361091. This is the first time I've used a 4-20ma sensor. I've used other 0-5V and 0-10V sensors before with voltage dividers and have been successful.

Can you help me understand how the A1 and A2 Analog Inputs on the B16M work to convert the 4-20ma signal into a voltage and what I should use for the gain? ChatGPT is trying to explain it to me but it describes using a 250ohm shunt resistor. How do I know what internal shunt resistor(s) have been used to convert the signal to be readable by the internal ads1115 chip?

I will be using 12VDC to excite the pressure sensor which is rated for 8-30VDC. The Wika test report shows that the sensor should produce 4ma at 0 bar and 20ma at 2.5 bar (36.2595 PSI). Here is a snapshot of my YAML code for esphome so far:

Good Morning

Is it possible send frequency through TCP to the KC868-A8 Transmitter?
thank you

Hi 

Can you suggest some software that I can use to model Kinkony devices wiring? Ideally I want Kinkony controllers and relays to be in that software library so I can drop them into my projects and design wiring.

I`m giving 1.5V DC at the analog input.

I save in the webserver my setup but I do not see any voltage at the Tuya app.

Any hint what is wrong ?

I just received my board.   The USB-C port does not respond at all, and when I connect to the network, the board has the IP address 192.168.1.200, but the only open port is 53.   I have put my computer on the same subnet and scan via UDP_SCAN_LIST and nothing is found.   I have tried holding both reset and download buttons (both together and at different times) and no results.

These are some notes on using a KC868 as an alarm controller.  The functionality is implemented as IFTTT rules implementing the alarm as ladder logic, although I've used text rather than graphical notation because you can't really do ladder logic in ASCII.  In this case DI 1-8 are PIR motion sensors and DI 9-12 are smoke alarm sensors.  There's sirens/strobes connected to DO 15-16.

In order to be able to do this you need to chain rules which the firmware currently doesn't support but there are requests to add it to the v3 firmware, at the moment I've worked around it by using a relay board to take the wet-contact DO output to the dry-contact DI inputs.  When support for this is added to the v3 firmware, e.g. by allowing DO outputs to be tested in IF conditions, then you don't need the external wiring.

1. Name = "Smoke", IF { DI 9-12 Rising Edge }, { Sensor1 Temperature >= 50 } THEN { DO On 3 15 16 }
   -- If any smoke or heat detector triggers then turn sirens on, chain to rule 8 via DO 3 -> DI 15.
   
2. Name = "Arm", IF { DI 15 Rising Edge } THEN { Delay 5s } { DO On 1 }
   -- If arm signal is received then wait 5s and turn on Armed output, chain to rule 7 via DO 1 -> DI 13.
   
3. Name = "Disarm", IF { DI 16 Rising Edge } THEN { DO Off 1 15 16 }
   -- If disarm signal is received then turn off Armed output, turn off Siren output, chain to rule 7 via DO 1 -> DI 13.
   
4. Name = "Entrance Motion", IF { DI 1 Rising Edge } THEN { Delay 10s } { DO On 2 }
   -- If motion is detected at the entrance then wait 10s and turn on Motion output.  This provides an entry delay to disarm the system. Chain to rule 7 via DO 2 -> DI 14.
   
5. Name = "Motion Main", IF { DI 2-4 Rising Edge } THEN { DO On 2 }
   -- If motion is detected elsewhere then turn on Motion output, no delay.  Chain to rule 7 via DO 2 -> DI 14.
   
6. Name = "Motion Basement", IF { DI 5-8 Rising Edge } THEN { DO On 2 }
   -- If motion is detected in the basement then turn on Motion output, no delay.  Chain to rule 7 via DO 2 -> DI 14.
   
   Connect DO 1 to DI 13 via NO relay.
   Connect DO 2 to DI 14 via NO relay.
   
7. Name = "Alarm Trigger", IF { DI 13 AND DI 14 } THEN { DO On 3 15 16 }
   -- If the alarm is armed, DI 13, and motion is detected, DI 14, turn sirens on.  Chain to rule 8 via DO 3 -> DI 15.
   
   Connect DO 3 to DI 15 via NO relay.
   
8. Name = "Siren Delay", IF { DI 15-16 } THEN { Delay 300s } { DO Off 1 2 3 15 16 }
   -- If sirens are turned on, wait 5 minutes then turn them off again, also turn off all arming signals and triggers.
   

Hi admin,
    when I click the serial port drop box, the app doesn't respond anything, it is freezing. I have already installed CH341 driver on my laptop for rs485 to usb config device. It showing the correct com port when I checked in device manager. But, I can't select the serial port in the app. I m using windows 11. Help me with that.

   

I m sure KC868-HA-V21 module is working normal. It is sending some data frame when I press k1 button in the serial monitor.

   

Hi is it possible through Kincony software to do such logic:
I would like to control two outputs the first output is to increase the flow of water the second to decrease the example:
temperature sensor measures the temperature of water that flows through e.g. a heater at a setting of, for example, 30 degrees it does nothing after exceeding e.g. by 3 degrees the logic turns on output ''1'' for 10 s (to increase the flow and at the same time reduce the temperature of heated water) the thermometer measurement would have to measurement of the thermometer would have to be taken at intervals, e.g. every 20 seconds (adjustable) and the principle of operation is reversed if the temperature drops after some time logic turns on output ''1'' to reduce the flow in order to equalize the temperature and so on and so forth the measurement would have to be taken at intervals due to the reaction time of cooling water.
Is it possible to set it up this way through the IFTTT website

It must work on the principle of a temperature controller only with a delay ( warm up or cool down response time)
