  • DIY Home Automation With ESP8266 (Linknode R4) and Amazon Alexa

    This is what I see in the serial monitor, repeated every 5 seconds. Should Alexa be able to discover this?ets Jan 8 2013,rst cause:4, boot mode:(3,7)wdt resetload 0x4010f000, len 1384, room 16tail 8chksum 0x2dcsum 0x2dv4ceabea9~ldConnecting to WiFiConnecting .....Connected to grandmaIP address: 192.168.1.27Begin multicast ..Udp multicast server started at 239.255.255.250:1900WebServer started on port:80WebServer started on port:81WebServer started on port:82WebServer started on port:83Adding switches upnp broadcast responderAdding switch : Light One index : 0Adding switch : Light Two index : 1Adding switch : Outlet One index : 2Adding switch : Outlet Two index : 3

    I had previously had success with this code, but today Alexa won't discover my WeMosD1. The D1 is connected to the same wifi net and the D1 is in the connected devices list in the router. Any hints on how to troubleshoot Alexa discovery?

  • DIY Home Automation with ESP8266 (Linknode R4) and Amazon Alexa

    I have the serial monitor open and I periodically see the following:------------------Got UDP Belkin Request..Sending response to 192.168.1.23Port : 50000Response sent !Sending response to 192.168.1.23Port : 50000Response sent !Sending response to 192.168.1.23Port : 50000Response sent !Sending response to 192.168.1.23Port : 50000Response sent ! ########## Responding to setup.xml ... ######## (three of these with a long line under each one beginning with "Sending :<?xml....")-------------------Is this just a periodic reconnection of the UDP link?

    What are the blank "#include" statements at the beginning of the code?

  • ESP8266 MPSM v.2 DevBoard - MAINS WIFI Web Power Switch

    I agree, but most of them are potted, so they need a bulky socket. I guess I'll be doing some destructive disassembly.

  • ESP8266 MPSM v.2 DevBoard - MAINS WIFI Web Power Switch

    I'd like to install this device remotely, near the load that is being switched. Does anyone have an easy way to generate Vcc from the mains? It can be done with a bridge rectifier, a resistor ladder, and a linear regulator, but the ESP8266 needs upwards of 200 ma when it's in transmit mode and the resistor ladder has to dissipate too much heat in order to provide a satisfactory voltage divider function to get down to a max of 35 volts feeding the regulator.
