This device uses WBR3 module which needs to be replaced with ESP8685-WROOM-01, ESP-12, ESP-C3-12F, ESP-12H, ESPC2-12 or ESP8684-WROOM-01C. Read more about module replacement in a detailed guide.

Module Replacement

!!! Unplug the Device before you open the Device !!!

Open the junction box on the Backside of the Heater by unscrew 4 screws with Philips Heads (PH2).

Now you have access to the Mainboard QNQ010W Ver1.1 with the Powersupply Model KB-5150.

With another 4 Philips Screws you can lift the mainboard up, and the WBR3 Chip will show up.

The WBR3 is simple connected with a 2,54mm Pin Header to the Mainboard.

Pinout (Topview, from Left to Right)

• TXD - Pin 16
• RXD - Pin 15
• VCC - Pin 8
• GND - Pin 9

So use an ESP-12S or ESP-12F and a 2,54 mm breadboard with max 30 x 25 mm size to replace the Original WBR3 Chip.

Configuration

backlog tuyamcu 11,1; tuyamcu 71,3; tuyamcu 72,2; tuyamcu 81,20; tuyamcu 61,19; tempres 0; tuyatempsetres 0; TuyaEnumList 1,9;

• Relay1 maps to dpID1 for power control

In the webUI an ambient temperature sensor, temperature set sensor and a Timer1 will be shown.

Set temperature using TuyaSend2 2,x where x is the desired temperature (0 decimals allowed).

Label webUI buttons:

webbutton1 Power;

TuyaEnum

As of Tasmota 9.1.0.1 #9769 it is possible to map Type4 dpIDs (such as dpID4) to an Enum fn ID.

Map dpID4 to Enum1 fnID:

TuyaMCU 61,19

Set Enum1 range (in this case the max enum is 9).

TuyaEnumList 1,9

Now you can control the timer with TuyaEnum1 <x> where x is a value between 0 and 9 (0 decimals allowed). If you try a number outside the Enum1 range it will throw an error.
