Hello,
I'm trying to use MCCI LoRaWAN LCCI library to connect to the Things Network, however the library requires IO1 pin of the SX1278 module to be connected to an GPIO of the ESP32.

I soldered a wire from SX1278 IO1 to ESP32 GPIO13 as that appears free and looks like a suitable pin.  However after doing that, the serial port would no longer appear on my PC, when i removed the jumper wire everything returned to normal.

Can you suggest any solutions?  Is GPIO13 ok for use?

Thanks in advance.

Hi all,

I want to measure Carbon dioxide PPM levels using the MH-Z19B sensor with my KC868-A4. The sensor uses UART and that means I need to use IO17 (#28 U2T) and IO16 (#27 U2R) but these are being used in the RS232 connector:

   

I see that I can easily use the IO16 (Number 9 from above picture) from the DB9 connector, but I don't know what is happening to IO17 (Number 10 from above picture).

To summarize my question, how can I utilize IO17 and IO16 from a KC868-A4 board? Is it even possible to use MH-Z19B sensor with it? I'm using Tasmota on it.

I'm apologize if this is a dumb question, I'm new to all this.


Thank you in advance

Hey!

Im new and just discovered the Kincony relays and its probably the best solution for my problem

My goal is basically: I want to be able to get an event in home assistant when I press the RF remote or a toggle switch to open the garage/gate door, so I can create an automation primarily to turn on the lights at night
I would only use the Kincony relay for the garage door and gate, my lights are already connected to home assistant

eg
toggle switch button was pressed, garage door opens -> turn on lights for 5min
or RF remote button was pressed, garage door opens -> turn on lights for 5min

Im a bit confused on 2 things
It says on the website the outputs are "277VAC 10A, 125VAC 12A", and I see nearly all other relay described as AC output aswell, the garage door and the gate is a 12v relay, can I still connect it?
When I connect a normal toggle light switch on the inputs to open the garage, can I set it up in "hold" and "toggle" mode or how is that managed? 

Thank you!

Here is KC868-A16 integrate with home assitstant by MQTT via "KCS" v1.0.15 firmware.

Is there some more technical information on this switch? I've recently ordered (still awaiting arrival) a KC868-A32 for controlling my blinds and was wondering how/if this panel could be hard-wired to the A32...?

I have a KC868-H16B relay controller, the mode is TCP Server.
I am trying to achieve that the controller will send it's status to the server that is put in Ethernet Setting. Does it work like that in the TCP Server mode and how to get the value for example using Nodered?

Thank you in advance!

hello...
first: ihave trying to connect kc868-h32bs to home assistant via mqtt
I followed this method:
https://www.youtube.com/watch?v=Yrat7hVzXRw
but i think its need to be updated because the mosquitto broker has a new way to configured
so can you plz update this section

second: where to found the new firmware version for h32bs thats compatible with mqtt.
thank you

Hello,

How can I make the toggle function with "KCS" if I have a conventional switch?  

Currently the conventional switch behaves like a "push" button: When I activate the key the light turns on, but when I put it in its initial position nothing happens, I have to activate it again so that the light turns off.

Thank you

Dear all,

which of the KC868-Series devices is capable of:

a) being directly powered with 24V DC

b) giving +24V as output

c) taking +24V as input

I‘m a little confused… I need only 3 inputs and 3 outputs.
