improvement:
1. Support connect to 2 cloud server work at the same time by UDP (KinCony's Cloud server) and MQTT (private MQTT broker server)

2. Fixed controller have delay time when send a large number of commands control relay in TCP Server mode.

3. add auto switch communication line function: if "wifi" and "ethernet " all use by "UDP" work mode connect to KinCony's cloud server. when ethernet line is disconnected (or bad), controller will switch to use "wifi", if ethernet cable is connected, then will switch to use ethernet line connect to cloud server again.

4. when use KinCony smart home app by "UDP" work mode, if turn ON/OFF any relay will feedback the relay state and digital input state to MQTT message.

5. add MQTT query relay state and input state command.
payload={"relay8":{"read":1}}  will feedback 8 relays and 8 input state

6. add RS232 command for wifi and ethernet work mode reset
send："reset-lan"          will set "ethernet" work mode by TCP Server and IP static=192.168.1.200
send："reset-wifi-lan"    will set "ethernet" and "wifi" work mode by UDP , IP mode by DHCP

Hello community,
Need some help with updating  to latest firmware
Setting :
   
- KC868 -32 : on cover indicated as 32BC2009xxxxx? on PCB indicated as 32L 
- Current firmware : V1.598
- no webpage available? : no response from http://192.168.41.123 ( IP address board)

When I update via the tool KC868-Controller-bootloader every things look fine but when restarting  no change ( on info via vircom)
V401_210205.bin : after 'run' command/restart  relays 2, 3,4,5  toggle on/off ( was an old test-scene programmed before firmware update saga) - no connection possible with PC software (old & new tool)
V419_210621.bin : idem
V420_210416.bin : after 'run' command/restart relay 2 comes on & stays on - no web access - no control via PC tool
V424_210509.bin : after 'run' command/restart relay 2 comes on & stays on - no web access - no control via PC tool
V429_210522.bin : no relays activated - no web gui - no control via pc control

Can I receive some  firmware in Hex (did not found them yet) format to upload it via ST-Tool?
Any other help greatly appreciated

improvement:
1. add relay control by webpage
2. support http command for developer integrate to third-party software to tun on/off relay and read relay state.
3. add web config password
4. add read input state http command for developer integrate to third-party software. you can send http command to get information of 6 channel digital input port state.
Command is like this, send:  http://192.168.1.xx/sw_ctl.cgi?RelayFF=R...pwd=XXXXXX
Then will feedback all state.
5. support use MQTT function by Ethernet or WiFi. it will easy integrate to third-party software, like home assistant...
how to integrate to home assistant by MQTT, see this link: https://www.kincony.com/kc868-h32b-integ...-mqtt.html
6. add option on config webpage, you can chose whether relay will remember the state before power off. Just whether receover relay sate when power on.
7. add option on config webpage, you can chose any relay channel for momentary work mode, and set the delay time for auto off. Relay "Momentary Time" extend to "1-10000 seconds"
8. add scan device Broadcast command for UDP. This command for software developer scan KC868-H32B in network.
use local network port=4000  send Ansi-String "scan" to remote IP:255.255.255.255 Port:4001
all KC868-H8B in same network device will feedback: device's IP,Port,UID,type
for example:
send->scan
feedback: 192.168.1.200:4196,uid:xxxxxxxxxxxxxxxxxxxxxxxx,type:H8B
9. Improve the stability of anti-interference, if ethernet line failure by interference , now will automatic restart ethernet chip.
make sure your KC868-H8B metal box top lable have "AT" words, like this photo. so that have 256KB flash memory enough for update. If not use the MCU chip, if you can weld, replace the MCU will support new firmware.

if you use MQTT, as follows:
Set your ethernet for MQTT in network setting webpage, set the broker IP,Port, MQTT user name and password.
Example configuration.yaml entry for relay1 output:
switch:
– platform: mqtt
name: ‘relay8B-1’
unique_id: relay8B-1
state_topic: ‘relay8/xxxxxxxxxxxxxxxxxxxxxxxx/state’
command_topic: ‘relay8/xxxxxxxxxxxxxxxxxxxxxxxx/set’
payload_on: ‘{“relay1”:{“on”:1}}’
payload_off: ‘{“relay1”:{“on”:0}}’
value_template: ‘{{ value_json.relay1.on }}’
state_on: 1
state_off: 0
Example configuration.yaml entry for input1 sensor:
binary_sensor:
– platform: mqtt
name: ‘H8B-input1’
unique_id: H8B-input1
state_topic: ‘relay8/xxxxxxxxxxxxxxxxxxxxxxxx/state’
value_template: ‘{{ value_json.input1.on }}’
payload_on: 1
payload_off: 0
Note: xxxxxxxxxxxxxxxxxxxxxxxx is your KC868-H8B’s ID, it’s 24bit. You can find in controller’s config webpage.

I just bought an H32B in order to control, through the smartphone, various equipment in my house (garage doors, lighting, etc..). From the tests I've done it seems to me that the hardware is reliable but the supporting application software is not very user friendly and difficult to understand how to configure and work. I ask, are you planning to improve support applications, namely "Smart Home"?
