ESP8266 gateway + WebServer = Awesome!

Yes, I see the difference. I'll try the bèta version tomorrow.

Hi,
I used the indications feature of MySensors 2.0 and a webserver to have the gateway provide status information through a web page:
This is how I did it:
In the global section I added this:
#include <ESP8266WiFi.h> #include <ESP8266WebServer.h> #include <WiFiClient.h> ESP8266WebServer WebServer(80); unsigned long startTime=millis(); unsigned long gwMsgSent = 0; unsigned long gwMsgRec = 0; String WebPage = "<h1>ESP8266 MQTT client for Mysensors</h1>"; void setupWebServer(); void showRootPage(); String readableTimestamp(unsigned long milliseconds);In the setup() Added this:
Serial.begin(9600); setupWebServer();Defined the following functions:
void setupWebServer() { WebServer.on("/", HTTP_GET, showRootPage); WebServer.begin(); Serial.println("WebServer started..."); } void indication( const indication_t ind ) { switch (ind) { case INDICATION_GW_TX: gwMsgSent++; break; case INDICATION_GW_RX: gwMsgRec++; break; default: break; }; } void showRootPage() { unsigned long runningTime = millis() - startTime; String page = WebPage; page+="<br>General information</br>"; page+= "<style> table, th, td { border: 1px solid black;}</style>"; page+="<table style=\"width:400\">"; page+="<tr>"; page+= "<th>Item</th>"; page+= "<th>Value</th>"; page+="</tr>"; page+="<tr>"; page+= "<td>Running for</td>"; page+= "<td>"; page += readableTimestamp(runningTime) ; page+= "</td>"; page+="</tr>"; page+="<tr>"; page+= "<td>Gateway messages sent</td>"; page+= "<td>"; page += gwMsgSent; page+= "</td>"; page+="</tr>"; page+="</table>"; page+="<br>MySensors gateway information</br>"; page+= "<style> table, th, td { border: 1px solid black;}</style>"; page+="<table style=\"width:400\">"; page+="<tr>"; page+= "<th>Item</th>"; page+= "<th>Value</th>"; page+="</tr>"; page+="<tr>"; page+= "<td>Gateway messages received</td>"; page+= "<td>"; page += gwMsgRec; page+= "</td>"; page+="</tr>"; page+="<tr>"; page+= "<td>Gateway messages sent</td>"; page+= "<td>"; page += gwMsgSent; page+= "</td>"; page+="</tr>"; page+="</table>"; Serial.println("WS: Send root webpage"); WebServer.send(200, "text/html", page); } String readableTimestamp(unsigned long milliseconds) { int days = milliseconds / 86400000; milliseconds=milliseconds % 86400000; int hours = milliseconds / 3600000; milliseconds = milliseconds %3600000; int minutes = milliseconds / 60000; milliseconds = milliseconds % 60000; int seconds = milliseconds / 1000; milliseconds = milliseconds % 1000; String timeStamp; timeStamp = days; timeStamp += " days, "; timeStamp += hours; timeStamp += ":"; timeStamp += minutes ; timeStamp += ":"; timeStamp +=seconds; timeStamp += "."; timeStamp +=milliseconds; Serial.println(timeStamp); return timeStamp; }And in loop() added the following:
WebServer.handleClient();If you have any more idaes on what to add to this page (I am thinking about maintaining a list of registered nodes and sensors) just post a reply!

No, it worked right out of the box, something that surprised me as well.
You do need Mysensors 2.0 for this.
You can check if you have a myindication.h file in the source tree of the Mysensors library. That file also contains the indications sent.

@Japio It's very easy to get information about available memory and wifi signal - just add
page+="<tr>"; page+= "<td>Free memory:</td>"; page+= "<td>"; page += ESP.getFreeHeap() ; page+= " bytes</td>"; page+="</tr>"; page+="<tr>"; page+= "<td>WIFI signal:</td>"; page+= "<td>"; page += WiFi.RSSI(); ; page+= " dBm</td>"; page+="</tr>"; -
Great! This will be added.
I am going to continue with the node and sensor status tomorrow.

Love this, subscribed. It's s such a shame I always has issues with my ESP gateway and had to revert to standard ethernet. The ESP always used to fail upon large amounts of traffic :(
I believe this was down to blocking code, is this resolved? (off topic).
BTW, is it possible to somehow record any failures?
-
Yes, this works!

Nice work @Japio
I'm working on a ESP8266 RFM69 Gateway myself and will definitely try this also.

@chrille said:
I am using the latest beta from github - it must be something else
It works on my NRF24 gateway, but not on the RFM69 gateway... Odd...
I'm curious if someone else with a RFM69 based gateway could this this- Jan

Would it be possible to add information about if a controller is connected to the GW WebHMI?
-
Is this still under development?
-
Yes, it actually is.
Current features:
- Stores wifi and mqtt broker configuration in flash. When no configuration is found, or the flash button of the ESP is pressed for 10 seconds, released, and then the reset button is pressed, it will restart in access point mode, allowing configuration to be done.
- Status page shows all nodes and sensors connected and the last sensors data and presentation time.
- Status indications on the box itself using a neopixel stick of 8 leds:
- Gateway status (operation or access point mode)
- Wifi strength
- Mqtt connection status
- Transmit error
- Receive indication.
I designed a board to nicely fit in a standard Aliexpress housing.
Main problem still is the instability of the ESP, it resets often, and I tried to work around it by maikng sure it resets quickly.
I am planning to make a more elaborate topic, including board designs soon.

@Japio perhaps you mean https://github.com/tzapu/WiFiManager ? I'm using that. It is pretty ok, but I would prefer something that had support for the async web server.

@mfalkvidd I know this is very old post but I stumble upon this while looking for esp gateway wifimanager git, can you share ur code if you don’t mind, save me time on re-inventing the wheel again...
