The Display- commands listed below can be used from the Tasmota web-console, MQTT, and from Tasmota Rules

The brightness of the display can be set using the DisplayDimmer command.ĭisplayDimmer 0.100 maps the brightness value to 8 steps from 0.7įor a minimum brightness, make sure this value is at least about 13 7-Segment specific Commands ~ To use the Seven-Segment specific Display- commands described below, set the DisplayMode to 0 with: DisplayModes ~ĭisplayModes 0.3 are supported. You can switch between these two variants with the following commands:ĭisplayType 0 - Use this for the Type 0 variant, with wiring similar to the TM1637 4-digit modulesĭisplayType 1 - Use this for the Type 1 variant, with a different wiring that causes the text 123456 to appear as 321654Īfter the ESP8266/ESP32 module restarts again, the display module is ready to accept commands. The 6-digit TM1637 has 2 known variants with different hardware wiring for the digit ordering. If you have a TM1637 with 6 digits, set the number of digits using the command: Once the GPIO configuration is saved and the ESP8266 / ESP32 module restarts, set the Display Model to 15 using the command: In the console, turn ON the display with the command Power 1. Thus, it is necessary to ensure that relays are numbered from 1, otherwise a conflict will occur with the display power. However, if there are additional relays defined, resulting in multiple power toggle buttons in WebUI, display power will create and map to the last button.

The power toggle button in webUI turns the display on or off. In Tasmota's Configuration -> Configure Module page, assign:įor example, if x=0 and y=2, z=4 then the module configuration would look like the following: The MAX7219 module needs to be connected to three GPIO pins and a 5V power supply. The TM1638 module needs to be connected to three GPIO pins and a 5V power supply. The TM1637 module needs to be connected to two GPIO pins and a 3.3V-5V power supply. set Brightness (8 levels) and Clear the display.display a Clock in 12 hr and 24 hr format.display basic Text, for example, sending the text 22.5^ will display:.display Numbers and Floats with control over position and leading zeros.The Tasmota support for these modules can.

These modules are a great way to add a simple numeric display to any MCU project. They use a two-wire (TM1637) or three-wire (TM1638 and MAX7219) I2C-like (but not exactly) protocol for communication with MCUs like the ESP8266 / ESP32 / Arduino etc., The TM1637, TM1638 and MAX7219 display modules are small (~ 10mm high digits) 7-segment, LED-based display units with 4/6 digits (TM1637), 8 digits and 8 digits (TM1638 and MAX7219) respectively.
