zum inhalt springen stammbaum about matthias mqtt – my simple switch for wardrobe and bed in the summer 2017 my wife and i furnished our bedroom with new furniture. the new wardrobe has now led lightning and the bed has also lightning integrated. but the bed has only one switch for the two led’s. switching the led right and left separately was not possible and switch the wardrobe led’s off while in bed was not possible. i doesn’t want a simple solution. i want something switchable with the smartphones. because i’ve experience with the esp8266 from my water level gauge i decide to build a switch for smartphones. i want make use of the mqtt protocol . it’s lightweight enough to implement into a small device like the esp8266. the hardware the led’s are supplied via a 12 volt transformer. the esp8266 needs 3.3 volts. so i decided to use a lf33cv for a stable 3.3 volts supply. for switching the led’s i use a bd237 transistor. from this schematics i’ve designed a small double layer pcb. i’ve packaged the eagle schematics and board into a zip file: mqttswitch i’ve ordered three pcb on aisler.net and after a few day i had three professional manufactured pcb’s in hand. with all the parts soldered on the pcb it looks like this. the software before this project i was not a big fan of the adruino develepment environment. but i’ve found that are many libraries out there for supporting the esp8266 in general and also the mqtt protocol on the esp8266. so i used this setup: adruino 1.8.5 ide: https://www.arduino.cc the esp8266 adruino extension: http://arduino.esp8266.com/stable/package_esp8266com_index.json the pubsubclient for adruino: https://pubsubclient.knolleary.net/ the fadeled: https://github.com/septillion-git/fadeled the led’s are fading in and out within two seconds. that’s adjustable by fading_time. the connection to the mqtt server can be established secure or unsecure. you can change the secure / unsecure setting with the defines unsecure_mqtt / secure_mqtt at the top of the sketch. and here is the complete sketch: /* mqttswitch matthias jentsch - april 2018 */ #define unsecure_mqtt //#define secure_mqtt #include <esp8266wifi.h> #include <esp8266wifimulti.h> #include <pubsubclient.h> #include <time.h> #include <fadeled.h> #define fade_led_pwm_bits 10 #define fading_time 2000 // update these with values suitable for your network. #define wifi_ssid1 "...................." #define wifi_password1 "...................." #define wifi_ssid2 "...................." #define wifi_password2 "...................." // mqtt connection #define mqtt_server "...................." #define mqtt_port 1883 // mqtt account #define mqtt_username "...................." #define mqtt_password "...................." #ifdef secure_mqtt // certificate fingerprint #define mqtt_server_fingerprint ".. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .." #endif // constants for wardrobe switch /*#define max_lamps 4 #define lamp1_pin 12 #define lamp2_pin 13 #define lamp3_pin 14 #define lamp4_pin 16 const int lamp_pins[] = {lamp1_pin, lamp2_pin, lamp3_pin, lamp4_pin};

special version for esp32 libftdi eclipse ide for c++ developers gnu arm eclipse plug-ins i’ve prepare a ready to use virtual box appliance for download. if you wouldn’t install all the software by yourself you can download the appliance. but be warned that’s a 3.23 gb download. https://matthias-jentsch.de/esp32.ova (3.23 gb) you can easily import this appliance into virtual box. the user account is esp32 with password esp32. installing the software: if you like installing all software by yourself you can follow these steps operating system linux os: ubuntu 16.10 desktop 64-bit running as guest on oracle virtual box 5.1.14 on windows 10 i’ve also installed the virtualbox 5.1.1
