F16 tuya reverse sw. function missing

[Karlis_LV]

Hello,
Please help me with some information. I have two questions about the KinCony F16 module (software nr. V3.18.0)  and Tuya.
I have connected simple momentary (non-latching) switches to the input channels to control lights. The switch has no fixation: one press turns the light ON, the next press turns it OFF.
Question:
Why, in the Tuya app (Simple Device Scenario),  I can configure the “Reverse Switch” function only for channels 1–6, while the other channels only have ON / OFF options.WHY?







Question 2:
Why is there such a noticeable delay / latency between pressing the button and the relay switching ON? It is very uncomfortable to use.
Is this a Tuya cloud-related issue, and if I use a local server (local control), will this delay be resolved?

if you want switch tun on/off relay. you should download KCS v3 firmware to your board. set by IFTTT, let digital input TOGGLE relay output. this is local way, it's fast speed. here is KCS v3 online guide: https://www.kincony.com/how-to-use-kcsv3...board.html
we don't suggest use tuya app set for wall switch, because it need internet cloud server, so it will have delay.

Hello,
I have two KinCony F16 16-channel ESP32-S3 relay boards and I want to build a hard-wired dimming solution for 4–6 LED strips using SR-2001DIN 1–10V dimmers.

I know KinCony already has a dedicated 0–10V dimmer board, but it is 16 channels and physically large. I only need about 4 channels, so I am planning to use a smaller external 0–10V analog output module instead.

I am looking at this RS-485 Modbus RTU analog output module (0–10V):

My questions are:
Is it possible to connect this Modbus RTU 0–10V analog output module directly to the RS-485 port on the KinCony F16? Can the F16 act as a Modbus master and control the registers of this analog output module? Is there an available firmware or configuration (KinCony firmware or ESPHome) that allows the F16 to work as an RS-485 gateway so Home Assistant can control the dimming channels through the F16, without using a USB-to-RS485 adapter? I want to avoid USB completely because I do not consider it safe or reliable for a permanent installation.

If this is possible, could you please explain what software configuration or setup steps are required?

Thank you very much.

i suggest you wait for some time, because new 4 channel dimmer board under produce.

I already have two F16 boards, and they are not cheap, so I expected them to be more universal.

From my understanding, the F16 seems to be mainly a relay (ON/OFF) controller. Please clarify what the RS-485 port on the F16 is actually intended for. Is it only for use as a Modbus RTU slave, or can it also be used to control external RS-485 devices?

Is it possible for the F16 to act as a Modbus master or gateway, so Home Assistant can control another Modbus device (for example a small 0–10V analog output module) through the F16 RS-485 port, without using a USB-RS485 adapter?

I want to understand whether the RS-485 interface can be used in real projects beyond simple relay control, or if the F16 is essentially just a relay controller.

Thank you.

1. RS485 port if enabled, relay work with SLAVE mode using modbus protocol.
2. sure, it's ok, if you config by esphome. if you want work as a MASTER.
