Topic: Sketch for using Alexa with a DUE / UNO .... (Read 242 times) previous topic - next topic


I see many solutions about using the ESP with Alexa but found no one for my DUE / UNO.

So here is a working script. It only needs the std Ethernet lib (with a little modfication).

Inspired by the Tasmota for ESP on github.

To get the IP from the Remote it is necessary to edit the Ethernet Lib (aktual version):

  Ethernet.cpp on the end of file:
      uint8_t *EthernetClient::getRemoteIP(uint8_t remoteIP[])
      W5100.readSnDIPR(sockindex, remoteIP);
      return remoteIP;

      Ethernet.h after virtual void stop(); (ca zeile 230)
      uint8_t *getRemoteIP(uint8_t RemoteIP[]);//adds remote ip address

I used Alexa Dot 3 Gen, i think it would work with 2 Gen too but not with 1 Gen, there you need to add the BRI stat every time. To do this take a look in the "xdrv_20_hue.ino" from Tasmota.

Not sure how many devices are possible, maybe up to 255.

I use it to switch 32 Relays on my DUE for home automation.
I use the DUE instead of an ESP cause i need 3 serial coms (RS485,RF,SMS usw) and many other pins.

I'm trying to use your sketch with alexa, but it's not working. Alexa cannot find the arduino. Can you explain how it's working?
