Hello everyone,
I have two F16 boards connected with HA that started to have connection issues.
The output from the MQTT logs:

here is KinCony AIO Hybrid smart controller work with oxygen modbus sensor using RS485
   
   
here is oxygen sensor modbus protocol:
   
here is config sensor in KCS "sensor" webpage, chose "modbus" type of sensor.
   

slave: 22
function code: 03
register: 104
data type: uint16
byte order: abcd big endian

KCS monitor will show the sensor value:
   

Hello!

i tried to put common the pin 3, on GND, then 12V, then GND again.... i tried directly to put 12V or GND, when inversed, with a wire directly to the contacts, not a peep? what am i doing wrong?
i thought that electrically speaking i go 12V to the houe bell switch, back to the input entry, and put the 12V- GND on common? but that simply doesn't do it?

I just recieved my module and want it to remember the relay state during power loss, how do I do that?

Thanks!

Hello, is there included any onboard overvoltage protections to switch inductive load? I need to switch electromagnetic valve 24V / 1A. Thanks

I am looking for a meter that supports split-phase or 3-phase; the N30 and others are too big for my project. Any chance the N10 supports split-phase?

 Looking to monitor Grid-tied Inverter generation and grid consumption. I already have a Victron Meter VM-3P75CT and am in need of a second meter with the same capabilities (L1,L2 and L3) and cheaper. This will be integrated to Home-Assistant and Node-Red running on my CerboGX.

 Maybe you can build an N5 with L1,L2 and L3 ?

Hi KinCony,
We are using the KC868-A16 and need four 4–20mA inputs.
AI1 and AI2 are already configured for 4–20mA, while AI3 and AI4 are configured for 0–5V.
We understand from the schematic that converting AI3/AI4 internally would normally require replacing the SMD resistors (5.1kΩ / 10kΩ network with the 0Ω / 150Ω configuration used on AI1/AI2).
We would prefer not to modify or solder components on the PCB.
We tested an external solution on AI3 by connecting a 220Ω resistor externally across the analog input and GND.
With a 4–20mA pH output connected, the controller showed pH 2.41, and we measured approximately 1.460V at the AI3 input. After taking the existing internal resistor network into account and applying the appropriate conversion in our ESP32 firmware, we were able to obtain almost the same pH value.
The measurement also appears electrically stable at the input.
Our question: Is using an external resistor in this way a safe and recommended solution for continuously using AI3 and AI4 as 4–20mA inputs?
Is there any disadvantage or protection/accuracy issue compared with changing the onboard resistors?
If you recommend a different external solution that does not require PCB soldering, please let us know.
Thank you.

I just purchased the A16S and was looking for a case for it if there is one.  I can also print one, but I am unable to find the board dimensions.  Can you point me in the right direction?

Thanks,
Ryan

Hi,

I have several questions on CO16 that I would like to use to replace my alarm system :-)

1/ Are there free GPIO that can be accessed (I need to add Wiegand input)
2/ Is there a socket to expand I2C bus ? 
3/ Which GPIO are used for KNX ? 
4/ With ESPHome can we send KNX messages from CO16
5/ Regarding the SIM7600E expansion, what is the wiring (I already have such a module and I would like to know if it will be compatible) 
6/ Any idea on how to generate sound for a remote loundspeaker (the one that tells alarm in service / door left open / ....) ?
7/ Is there any electronic between GPIO38/39 and RS485 socket ?

Regards
Philippe
