ESP8266 gateway + WebServer = Awesome!

[chrille]

@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?

[Japio]

Yes, this works!

Awesome. :smile:

Nice work @Japio

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

[chrille]

@korttoma I'm looking forward to hear your results, as I couldn't get it to work with RFM69. However, there doesn't seem to be transport specific code for indication(), so I really don't understand why it works with NRF and not RFM

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

I created an issue for this, but I'm still interested in hearing from other RFM69 users

@chrille Please see my comment on github

[korttoma]

Would it be possible to add information about if a controller is connected to the GW WebHMI?

[Mark Swift]

Is this still under development?

[Japio]

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

Where did this all end up?

[pihome]

@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...

[mfalkvidd]

@pihome I have a sketch at https://github.com/mfalkvidd/Arduino-Datormagazin-Pomodoro/blob/datormagazin/Arduino-Datormagazin-Pomodoro.ino but I think it is easier to just follow the instructions in the wifimanager readme.
