Can the usb-c port be used to power another device?

Sat, 06 Dec 2025 17:28:42 +0800

I was thinking of powering a small switch which draws 0.6A at 5V from the usb-c port on a F24, is this possible?

Recommended way to integrate into home assistant

Wed, 26 Nov 2025 16:25:30 +0800

Hi,

Can you tell which is the recommended way to integrate with home assistant OS running on a raspberry pi 5? I'm looking for the most reliable method with a latency of less than 200ms to activate a relay.
* kcs firmware with mqtt over wifi
* esphome firmware with esphome over wifi
* usb (is this supported on home assistant OS?)
* bluetooth (is this supported as a client, and is it supported on home assistant OS?)
* ...?

Thank you,
Bernard

adding HAv2 into Discoverable MQTT for homeassistant

Fri, 07 Nov 2025 18:12:17 +0800

I would like to use the discoverable entity for homeassistant , is it possible that the 485 interface HAv2 can also be adopted this way into home assistant?

F24 and KC868-AP dimmer sharing same wall switch panel

Mon, 18 Aug 2025 15:13:37 +0800

Hello,

Can I use one multi-gang Kincony momentary wall switch with different devices, one device per gang? I want a 2-gangs switch:

- Gang 1 to an F24 (to control a light bulb by software)
- Gang 2 to a KC868-AP (ESP32) dimmer (to control an LED strip).

Is this wiring possible?

Many thanks

My questions:

Is the 433MHz receiver really connected to native GPIO40 of the ESP32?
Is this GPIO compatible with the RMT hardware required by remote_receiver in ESPHome?
Could the RF receiver be connected via an I²C expander (like PCF8574), or is it mapped internally in another way?

Thanks for your support!

[arduino code examples for F24]-09 how to communication with Tuya WiFi module

Thu, 28 Nov 2024 19:49:35 +0800

Code:
/*

 * Made by KinCony IoT: https://www.kincony.com

 * 

 * This Arduino program implements communication between ESP32 and the Tuya module

 * via UART (serial communication). It listens for specific packets from the Tuya module

 * and responds according to the predefined commands.

 * 

 * Functionality:

 * 1. When the ESP32 receives a heartbeat packet (55 AA 00 00 00 00 FF),

 *    it sends a heartbeat response (55 AA 03 00 00 01 00 03).

 * 2. When the ESP32 receives a product information request (55 AA 00 01 00 00 00),

 *    it sends a product information response (55 AA 03 01 ...).

 * 3. When the ESP32 receives a work mode request (55 AA 00 02 00 00 01),

 *    it sends a work mode response (55 AA 03 02 00 03 10 1C 14 47).

 * 4. When the ESP32 receives a network status request (55 AA 00 03 00 01 00 03),

 *    it sends a network status response (55 AA 03 03 00 00 05).

 * 5. Subsequent heartbeat packets (55 AA 00 00 00 00 FF) are responded to with

 *    (55 AA 03 00 00 01 01 04).
