correct device purchase

[ulfgar]

ok so I only purchase KC868-A16 and connect the magnetic sensor and motion sensor cables. Which firmware do I need to install to be able to see the sensors on home assistant and tuya?

[admin]

you can see KCS firmware, here is online guide: https://www.kincony.com/esp32-kcsv2-firmware.html

I purchased the kc868-A16, I installed the KCS firmware found here https://www.kincony.com/forum/showthread.php?tid=3791 and everything was fine, I connected 1 magnetic sensor as a test and since browser I can see it without problems. I would like to integrate everything into home assistant, how can I configure esp home? in the home assistant integrations it gives me the message Unable to connect to ESP. Make sure your YAML file contains an "api:" line.
How is it created?

here is ESPHome yaml file for KC868-A16: https://www.kincony.com/forum/showthread.php?tid=1628

Do I create a new file in the home assistant package folder and call it kc868-a16.yaml and restart?

[admin]

firstly, install ESPHome addon on your home assistant.
then create a new device for KC868-A16 (will create new yaml for KC868-A16)
if you don't know how to do , here are some ESPHome beginner guide videos, you can check this firstly: https://www.kincony.com/forum/forumdisplay.php?fid=54

Ok, I solved it by putting the file as you indicated, the problem is that from home assistant everything works but I can no longer access the web interface by going to the device's IP.
Isn't it possible to integrate the sensors in home assistant while also maintaining access from the Cloud?
By abandoning the esphome integration and sando tuta or mqtt could I?
How could I do it?

Do you means you can use KCS firmware and home assistant at the same time? Because of you downloaded esphome firmware, overwrote the ESP32, KCS firmware not exist now.
if YES, you can download KCS firmware to relay board, then integrate board to home assistant by MQTT. so that you can use KCS firmware all functions and home assistant at the same time.

ok, I'm using mqtt and I have integrated the inputs and outputs as in the example file but the example of the integration of the 433 receiver and the 433 transmitter is missing. Could you kindly tell me the code to insert in the Configuration.yaml

[admin]

here is ESPHome information about RF sender and receiver.

because of you need modify the yaml according to your requirements.
