AS-ESP32-S3 won't initialize

Fri, 20 Mar 2026 02:49:56 +0800

I just purchased a AS-ESP32-S3 device to act as a voice assistant for my Home Assistant. When I received the unit, something inside it was rattling around loosely - like something had broken inside. Not sure if that's ultimately important or not.

When I plugged the device into the HA server, all of the lights turned blue and a tone built up in about 3 steps to a steady tone. The tone continued without stopping for as long as I had the device plugged it (up to 15 minutes, when I unplugged it). It doesn't seem to me that it was flashed with any new firmware as described in this YouTube video: https://www.youtube.com/watch?v=g-KsrZjFljY

While the tone was sounding, I did try to configure the device in my home assistant. I selected "Add Device", saw ESPHome and selected it, and was presented with a modal asking for the host ip address, which I provided. I got a "Unable to connect to the ESPHome device. Make sure the device's YAML configuration includes an 'api' section." as shown in the attached screenshot. I have no way to access any YAML that the device might be using since I can't access the device and can't do anything with it in Home Assistant.

What do I do to get this thing working?

Device change after damage

Fri, 06 Mar 2026 05:09:34 +0800

Hi all. I have a question. I am using a B24M configured as MQTT with Home Assistant. After it was damaged, I bought a new device. How can I replace the device while keeping the existing integrations (so that a new device is not created, but it replaces the damaged one)? From what I see, the device is identified using a UID in the MQTT broker, so I guess I would need to somehow replace that.

TA with Home Assistant with Ethernet Only

Tue, 03 Feb 2026 06:54:07 +0800

How do I get the Tiny Alarm System (TA) to work with Home Assistant?

The yaml example at this post is set to use wifi. I want to use ethernet / poe only.

However, if I remove the wifi components, this line:

PHP Code:
- platform: tuya_wifi_mcu 

is located all over the place.

Does anyone have a complete yaml example without any wifi (ethernet only)?

Kincony KC868-A4 flashen not work

Wed, 19 Nov 2025 15:35:43 +0800

Beste forum,
ik heb twee Kincony KC 868 A-serie IO-boards, één A4 die werkt met ESP Home en Home Assistant, maar de andere A4 ESP kan niet worden aangesloten. Het verbindingsboard is aangesloten via USB en blijft laden, het board schakelt relais en de zoemer om zonder resultaat. Moet dit board in de flashmodus worden gezet? Zo ja, hoe werkt dat?

Esphome + KC868-HA-V21

Wed, 13 Aug 2025 16:45:42 +0800

Hello, friends. Thank you so much for your products—I’ve been using them with great pleasure. However, I’ve encountered an issue while trying to set up your KC868-HAv21 RS485.

I connected it via RS485 to the KC868-A2, using the ESPHOME firmware. I added your component from GitHub, and the settings on the HAv2 are factory defaults. Controlling the digital outputs (D1-D6) works fine, but when it comes to changes in the state of the digital inputs, the ESPHome logs only show the following messages:

text
dump kc868_ha config, target_relay_controller_addr=1, switch_adapter_addr=10, bind_output=1
dump kc868_ha config, target_relay_controller_addr=1, switch_adapter_addr=10, bind_output=2

dump kc868_ha config, target_relay_controller_addr=1, switch_adapter_addr=10, bind_output=8
found a kc868_ha board, target_relay_controller_addr=1, switch_adapter_addr=10, bind_output=1 (also bind output 1-8)
What am I doing wrong? Could it be due to incorrect bind_output parameters? If so, which numbers should I specify?

I took the binary_sensor configuration from your GitHub and followed the instructions from your YouTube channel exactly. Thanks for your help!

Need help choosing modules for 32-channel lighting control with Home Assistant

Mon, 30 Jun 2025 20:23:40 +0800

Hello everyone,
I'm new to KinCony and Home Assistant. I would really appreciate your help.
I want to control my house lighting using Home Assistant, and I need to manage 32+ channels. I’m looking for a solution with the best price/performance.
Important:

I am not a programmer, so I need a system that works without writing code, just ready firmware like ESPHome or KinCony’s firmware.
I really like KinCony devices, but unfortunately I can't find compact and complete information in one place that explains how to set up a simple lighting project using a few modules.
I prefer using I/O extenders (relay modules) that come in a solid metal case or at least with mechanical protection, not open PCB boards.

Could you please help me with:

Which modules do I need to build a 32+ channel Home Assistant lighting control system?
Is there a video or full guide that shows everything: connection, flashing (if needed), and control via Home Assistant?
Can this setup work without programming knowledge?
What is the best I/O expander module with relays that includes a metal or protected enclosure?
Can the system run only on Server16 with CM4 + some simple extender relay board?

I want to build a clean and reliable lighting automation system with good enclosure protection and Home Assistant support.
Thank you very much for your help!

B16M Outputs & HomeAssistant Firmware

Sun, 23 Mar 2025 11:06:47 +0800

Hi all,
I've recently deployed a Kincony B16M and flashed it with the stock kincony-b16m.yaml config.

I’m using the digital outputs to control HF41F relays mounted on 41F-1Z-C2-1 boards.
Each relay coil is connected with a 1N4007 flyback diode across A1 and A2. Wiring is as follows:

+12V DC to A1
1N4007 across A1 and A2 (cathode on A1)
A2 wired to DO1
DC port connected to -12V (to complete the circuit)

The issue:
When the B16M boots, DO1 immediately energizes the relay, even though in the WebUI the output appears OFF. Toggling DO1 via the WebUI has no effect on the relay—it remains stuck on. I’ve tried both

inverted: true

inverted: false in the YAML under b16m-output01, but neither changes the behavior.

Here's the relevant YAML snippet:

Code:
switch:

  - platform: gpio

    name: "b16m-output01"

    pin:

      pcf8574: pcf8574_hub_out_1

      number: 0

      mode: OUTPUT

      inverted: true

At this point I’m trying to determine whether I’m dealing with a hardware issue or if there’s a nuance with the output logic I’ve missed. Any insights would be appreciated.
Thanks in advance.

Do you have or can suggest any devices for water supply automation with Home Assistant support?

I wonder if these can work

how to use binary sensor send SMS by SIM7600E 4G module in ESPHome
