Hello, I've just bought this device and after some preliminary tests I've noticed that IR range is terribly poor comparing to my another transmitter, which is a cheap Tuya based device.

Is it a matter of weak IR LEDs or reason is something else?

KC868-A16 Ethernet ESP32 Development Board

does anyone know how to make alexa work using this through the LAN? how to would be awesome i have NO IDEA!!! PLEASE HELP!!! 
Also i want the inputs (dry contact)  to trigger the outputs, 

if someone wants to message me and spend some time to teach/ show me how im willing to pay,

thanks again!

hello every one
i have h32bs integrated in home assistant by mqtt  . please see pictures
how can solve it

Hi, I would like to equip my fireplace insert with an automation that will measure the temperature of the flue gas in the chimney and control the air supply damper based on that.


Hi, I would like to equip my fireplace insert with an automation that will measure the temperature of the flue gas in the chimney and control the air supply damper based on that.

Systems like this can make the whole burning process much more efficient, using up to 30% less wood. Which is great. Plus, they can be very user-friendly and alert the user to add wood to the fireplace.

All you have to do is measure the temperature with a ceramic sensor that can withstand high temperatures and a servo drive to control the air supply damper.

All the logic should be able to be set up through Home Assistant.

• Which HW Kincony would handle this and how?
  
• Can you give me any advice?

Hi! 

I have recently purchased a KC868-A8S.

My goal is to get a GSM web server, from which I can activate the relays.

I have managed to create a web server by creating my own AP, taking a tutorial from the forum as an example.


But this, although it is something similar, does not serve my purpose.

I have worked before with ESP32 and GSM (I used to work with TinyGSM), and when I wanted to connect it was necessary to define the MODEM_TX and MODEM_RX pins in code.

In this case I cannot find anywhere, neither in the documentation nor in the forum, how to connect the ESP to the GSM network, nor to which pins the modem corresponds.

I have a SIM800L module.

Is there an example of code (.ino) in which the configuration and connection of the GSM can be seen logically?

Any help is appreciated.

Thank you very much in advance and sorry for my level of English.
