Ease connection of Wifi sensors to Router

[openhsorg]

Problem: We have 50 home sensors based on Wemos (ESP-8266EX) and we need to connect each of them to home router. This must be intuitive and easy done by end user. This has been issued from: https://github.com/openhsorg/openhs/issues/38

Proposal of solution:

1. Turn on wifi sensors
2. Open OpenHS admin page and see a list of these sensors
3. Mark all of them or select only some of them and press connect. In dialogue enter SSID credentials (home router login:passwd) Insert also MQTT server data.
4. The similar approach when we want to disconnect sensors

Study materials and similar solutions:

1. I attached an example of home extender - how it deals with router connection extender_www.pdf
2. Project which deals with this problem: https://github.com/tzapu/WiFiManager
3. How to make web-server on wemos: http://www.arduino8.cz/hrajeme-si-wemos-d1-web-server/ and http://www.arduino8.cz/hrajeme-si-wemos-d1-web-server-2/
4. Update Wemos software via Wifi: http://www.arduino8.cz/hrajeme-si-wemos-d1-nahrani-programu-pres-wifi-ota/

This project: https://github.com/tzapu/WiFiManager at the beginning switches Wemos into Access Point mode which can be connected directly from another computer via http:// where user can enter wifi and MQTT credentials.

Next step is figure out how to enter credentials from openHS page into more connected ESPs in Access Point mode.

This project solves the issue: https://github.com/marvinroger/homie-esp8266 Scenario:

1. Wemos boots into config mode (Access point)
2. Connect to the access point and send JSON config with credentials (wifi, MQTT):
   curl -X PUT http://homie.config/config --header "Content-Type: application/json" -d @config.json Credentials are in EPROM

The issues TB solved:

1. return back to config mode for a change of credentials: a/ we need external button, b/ format file system:

   include "FS.h"

void setup() { Serial.begin(115200); Serial.println(""); Serial.println("Mounting FS...");

if (!SPIFFS.begin()) { Serial.println("Failed to mount file system"); return; }

SPIFFS.format(); Serial.println("Done."); }

void loop() { }

2. Java module must do this work for each sensor

Connection problem arises. How can i connect to my router by WAN from another city ? I have a router at my hone and want to connect it from my workplace computer

capability will be moved to MQTT gateway...
