Software

Wired (I2C)(Quickstart):

Connect the Dimmy PCB to the VAN PI Relayboard via JST PH 4pin cable and it will work directly. (Using VAN PI OS)

Standalone (ESP32-WEMOS) (Quickstart):

Control the 7 Channel via GPIO button/switches

• supports dimming by keeping pressed

• sleep timer (long pressing while active)

• S1 –> all

• S2 –> LED 1

• S3 –> LED 2

• S4 –> LED 3

• S5 –> LED 4

• S6 –> LED 5

• S7 –> LED 6

• S8 –> LED 7

WiFi (ESP32-WEMOS)(Quickstart):

Connect the Dimmy via WiFi to the VAN PI. (Using VAN PI OS)

Pekaway Mota Wemos d1 (Esp8266/Esp32):

Flash Pekaway Mota with our Onboard Flasher or with our Online Flasher.

• Supports dimming via VAN PI OS (MQTT)
• Supports reading DS18B20 via 3pin Connector
• Supports GPIO Readings -> in development - esp32 8xGPIO - esp8266 4xGPIO

Firmware pekawayMOTA We compiled a custom version of Tasmota.io, to add the support for the PCA9685 PWM Controller. You can flash the firmware with the onboard flasher using the VanPi system or you can use our Webinstaller.
