Setting

Relay Connect

Support protocol
Dingtian-String
Dingtian-Binary
Modbus-RTU., Modbus-ASCII, Modbus-TCP/UDP
CoAP
HTTP GET CGI(control relay, get input/relay status)
Input Mutual Control
MQTT(input/relay status change, report to your MQTT server auto)

Relay Task

Please sync the time on “setting” webpage firstly, you can config when relay ON and when relay OFF automatically

Input Link Relay

Input status change active relay ON/OFF, DELAY, JOGGING(PULSE),FLASH,TOGGLMOTOR
To config “Motor” to control motor (blind)

Input Link URL

Input status changes will active HTTP URL

Input Relay Alias

Rename input/relay to understand better

IP WatchDog

It can ping and reboot other device when network is OFF

Transparent Transmission

Repost data which is from your device through our relay board to your PC from UDP/TCP to RS485/CAN,vice versa

Upgrade

Upgrade new firmware by webpage

Support Domoticz /Home assistant (HA Discover)/openHAB

IP Finder to search device, support different network segment
