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?

comme je suis debutant en arduino/ESP32S3, il me semble que la syntaxe manquant devrait comprends une fonction disable par fonction mais sur pas encore un as en arduino..mdr
j'ai besoin de votre lumiere merci d'avance. cela parce preparant le code pour le relay T16M.
la config : AIO maitre , T16M : Esclave pour compense le manque d'entrées /sorties de l'aio Hybride en reseau modbus , avec un ecran 7 pouces en Modbus . pour la programmation suis partir sur un melange en arduino avec EditeurPlc pour la partir PLC.
en autre , pour ce dernier , on doit declarer les variables externes ESP32S3, donc partir programmation sur le T16M me semble une bonne idee , merci de votre reponse.

Hi,

I would like to ask for advice on which KinCony products would be best for controlling my water‑based underfloor heating system.

System layout:
Upstairs: 4 heating loops (manifold circuits) to be controlled separately.
Ground floor: 3 heating loops to be controlled separately.

In addition, I need to:
Switch the ground floor zone valve and the upstairs zone valve. 
Provide a boiler enable signal via a volt‑free (dry) contact.

The existing “dumb” system should remain functional in parallel at first:
There is one programmable thermostat for the upstairs and one for the ground floor.These currently control the boiler and the two main zone valves.

Hardware idea:

I already have a KC868‑A8, which I plan to use for the ground floor (3 loops + ground‑floor zone valve  + upstairs zone valve + boiler enable + some spare relays).

For the upstairs I am considering a KC868‑A6, which would handle the 4 loops and the upstairs zone valve. 

A small amount of wiring between the floors is possible.

Control requirements:
I would like the basic heating logic (room thermostats, loop valves, zone valves, boiler enable) to run locally on the KinCony devices themselves, without depending on any central controller (so that heating continues to work even if Home Assistant or the network is down).

At the same time, I would like to be able to override or adjust the behaviour from Home Assistant when desired (setpoints, manual on/off, etc.).

Questions:
Does the combination KC868‑A8 (ground floor) + KC868‑A6 (upstairs) make sense for this scenario, or would you recommend a different KinCony board combination for 7 loops + 2 zone valves + boiler enable?
What is the recommended way to implement the local control logic on these boards (KinCony original firmware rules, ESPHome, Tasmota, custom ESP32 code, etc.), given that:
It should work safely and autonomously.
It should still be easy to integrate with Home Assistant.

Could you recommend any wireless room thermostats that can communicate directly with KinCony hardware (for example via LoRa, nRF24L01, 433 MHz, or another protocol supported by KC868‑A series), so that I could replace the existing wired thermostats completely in the future?

Any wiring diagrams, example projects or firmware configurations for a similar 2‑floor underfloor heating system would be very helpful.

Thank you in advance for your support!

Hi, unfortunately the flashing of the Kincony A8 failed. I flashed a compiled esphome bin file. It stopped always after a few percent. I tried multiple cables and an different baud rates. No success and now it is not responding anymore / seems bricked. I was working from a linux device:

It is the first time ever I had such an issue with an esp device. And I use them a lot - with WLED, custom procects etc. Is there maybe something wrong with the pcb design?

I hoped by buying a more expensive relais board to get not into trouble.

Hi everyone,
I’m struggling with a Kincony KC868-A16 board (ESP32-based) integrated with ESPHome in Home Assistant. I can see all the entities (switches and binary sensors) in my HA dashboard, but none of the physical relays or digital inputs are responding.
The Hardware:

• Board: Kincony KC868-A16 (V1.5 or similar with 4x PCF8574 IO Expanders).
  
• Power: Externally powered with a stable 12V 2A DC supply.
  
• Checked with Multimeter: PCF8574 chips are correctly powered at 3.3V.
  

• Code:

  Found device at address 0x21
   (Inputs)
  
• Code:

  Found device at address 0x22
   (Inputs)
  
• Code:

  Found device at address 0x24
   (Outputs/Relays)
  
• Code:

  Found device at address 0x25
   (Outputs/Relays)
  

Hello, is it possible to restart the board (KC868-A2 or KC868-A4S, KCS v2 firmware) using IFTTT and Custom Protocol?
Any advice would be greatly appreciated.

Francais :
Serait-il possible de connaitre la référence de la pile bouton qui doit va dans le rtc battery socket  qui peut-être mis sur le AIO pour maintenir sa sauvegarde.
Cordialement.

English :
 Could you please provide the part number for the button cell battery that fits into the RTC battery socket, which can be installed on the AIO to maintain its backup?
Regards.
