LC Technology WiFi Relay - Single Relay

In order to use LC Technology WiFi Relay for 1 relay version, please

  • Set module to Generic (in module configuration and click save)
  • Set i.e. GPIO12 as Relay1 (in module configuration and click save)
  • Disable seriallog (type seriallog 0 in the tasmota console)
  • Enable rules (type rule1 1 in the tasmota console)
  • Add the following rules typing in the console: Rule1 on System#Boot do Baudrate 9600 endon on Power1#State=1 do SerialSend5 A00101A2 endon on Power1#State=0 do SerialSend5 A00100A1 endon
  • Note: If that doesn't work for you, you may find that using Power1#Boot as the event to trigger the baudrate setting (instead of System#Boot) works, as it did for me. So the alternate rule one command is.. on Power1#Boot do Baudrate 9600 endon on Power1#State=1 do SerialSend5 A00101A2 endon on Power1#State=0 do SerialSend5 A00100A1 endon

LC Technology WiFi Relay - Dual Relay (note, older versions of this board used a baud rate of 9600, so if 115200 doesn't work, try 9600)

To configure an LC Technology ESP8266 Relay X2, use the following settings...

  • Set module to Generic (in module configuration and click save)
  • Set GPIO0 and GPIO2 as Relay1 and Relay 2 (in module configuration and click save)
  • Disable seriallog (type seriallog 0 in the tasmota console)
  • Enable rule1 (type rule1 1 in the tasmota console)
  • Enable rule2 (type rule2 1 in the tasmota console)
  • Add the following rules typing in the console:

Rule1 on System#Boot do Baudrate 9600 endon on Power1#State=1 do SerialSend5 A00101A2 endon on Power1#State=0 do SerialSend5 A00100A1 endon

Rule2 on Power2#State=1 do SerialSend5 A00201A3 endon on Power2#State=0 do SerialSend5 A00200A2 endon

Beware of counterfeit modules

If your board just continuously flashes its led when powered on and no esp-01 is entered, the onboard STC15F104W needs to be programmed! For more details see https://www.esp8266.com/viewtopic.php?f=160&t=13164&start=68#p74262

Additionally once programmed, you may also have to remove r4, some issues exist where r3 and r4 are swapped, but just removing r4 works.
