+ | ===== setup and development ===== | ||
+ | first [[setup_arduino_ide_for_esp8266]] and install the WiFiManager via the '' | ||
+ | |||
+ | - navigate to ''< | ||
+ | - <code bash>rm -rf WiFiManager | ||
+ | git clone https:// | ||
+ | cd WiFiManager/ | ||
+ | git branch -a | ||
+ | git checkout remotes/ | ||
+ | </ | ||
+ | |||
+ | ==== get wifimanager to work ==== | ||
+ | that's actually fairly simple.. just include it and put '' | ||
+ | <code cpp> | ||
+ | #include < | ||
+ | #include < | ||
+ | #include < | ||
+ | #include < | ||
+ | |||
+ | WiFiManager wifiManager; | ||
+ | |||
+ | void setup() { | ||
+ | // put your setup code here, to run once: | ||
+ | Serial.begin(115200); | ||
+ | wifiManager.autoConnect(); | ||
+ | wifiManager.startWebPortal(); | ||
+ | } | ||
+ | |||
+ | void loop() { | ||
+ | // put your main code here, to run repeatedly: | ||
+ | wifiManager.process(); | ||
+ | } | ||
+ | </ | ||
+ | |||
+ | |||
+ | ==== add enOcean ==== | ||
+ | now we can finally add the enocean receiver to our setup. we therefore connect the +3.3V to the +3.3V of the Wemos D1, the GND to the GND and we cross connect the RX of the enocean Module to the TX of the Wemos D1 and the same for the TX fo the enOcean that goes to the RX of the Wemos | ||

+ | next we need the [[http:// | ||

+ | if(ap.connected()){ | ||

+ | ap.println(" | ||
+ | break; | ||

+ | delay(500); | ||
+ | } | ||
+ | } | ||
+ | } | ||
+ | } | ||
+ | |||
+ | void debug(const char *message){ | ||
+ | if(debugOnline){ | ||

+ | } else { | ||
+ | Serial.println(" | ||

+ | _Msg.decode(); | ||
+ | if (_Msg.dataAvailable() == true){ | ||
+ | | ||
+ | } | ||
+ | } | ||
+ | |||
+ | void debugHex(int payload){ | ||
+ | if(debugOnline){ | ||
+ | ap.println(payload, | ||
+ | } | ||
+ | } | ||

+ | void loop() { | ||
+ | // put your main code here, to run repeatedly: | ||

+ | debugHex(_Msg.getSenderId()); | ||
+ | } | ||
+ | } | ||
+ | delay(50); | ||
+ | } | ||
+ | </ | ||
+ | now you should see output like this on your netcat console after you started the sketch and then pressed a button: | ||
+ | < | ||
+ | connected | ||
+ | hello world | ||
+ | new payload received: | ||
+ | 70 | ||
+ | 3102F7 | ||
+ | new payload received: | ||
+ | 0 | ||

+ | ==== MQTT ==== | ||
+ | next up is MQTT support throught he [[https:// | ||
+ | I should have done this right after implementing the WiFiManager as one could also use mqtt for debugging messages rather than trying to use AsyncPrinter which did not work in conjunction with mqtt and was painful to figure out in the first place. so now this contains a solution for debugging via mqtt. | ||
+ | |||
+ | download the [[https:// | ||
+ | |||
