Hi,
I’m trying to setup a remote garage door monitor and control IoT thing. This is my hardware:
Philmore N.O./N.C. Magnetic Reed Switch, SPDT : 30-10072
Adafruit Assembled Feather HUZZAH w/ ESP8266 WiFi
Adafruit Non-Latching Mini Relay FeatherWing
Adafruit Assembled Terminal Block Breakout FeatherWing for all Feathers (optional)
I’m running gateway version 1.0.0. Here is my ESP8266 code:
/**
- Simple server compliant with Mozilla’s proposed WoT API
- Originally based on the HelloServer example
- Tested on ESP8266, ESP32, Arduino boards with WINC1500 modules (shields or
- MKR1000)

}
Everything works. When I open the reed switch the state change is reflected on the web page. I can use the Open/Close toggle to cause the relay to operate. These are the issues I’m seeing:
- When I go to ADD my ESP8266 two different devices show up in the list.
Is there something in my ESP8266 code that is causing two devices to show?
-
I would like to get a running text log of every time the door opens or closes either by local actions (button mounted in the garage or car remote) or by interaction with the webpage. The code to decide which action caused the door to change state is straight forward. I’m having problems with getting EVENT’s to work. The code will generate an EVENT and I can see the events at https:///things/door/events but not at the website. Can anyone explain how to get the events to show up on the webpage?
-
The Open/Close device I used to control the door works, but a push button would be a better device to use to mimic the real button installed in the garage. I’ve read that the PushButton device does not send information from the web page to the ESP8266. Is that correct? Can the definition be changed (or a new device created) to cause information to flow from the web page to the ESP8266?
TIA
