 so lets try also
 ===== Tasmota =====
-also check out my detailed description for the [[sonoff]] setup. basically download the latest [[|release]] and then copy the lib folder into your arduino ''sketchbook/libraries'' folder. then edit the ''my_user_config.h'' file and make sure the '''' is enabled.
+also check out my detailed description for the [[sonoff]] setup. basically download the latest [[https://github.com/arendst/Sonoff-Tasmota/releases|release]] and then copy the lib folder into your arduino ''sketchbook/libraries'' folder. then edit the ''my_user_config.h'' file and make sure the ''#define USE_BMP'' is enabled. also sest the ''#define MODULE'' to ''WEMOS''. as a side-note: this will be called "Generic" in the web-interface but in the source code it's still called WEMOS.
+the [[https://github.com/arendst/Sonoff-Tasmota/wiki/Wemos-D1-Mini-and-BME280-Temperature,-Humidity-and-Pressure-Sensor|hardware setup]] looks like this (note, the scl and sda lines could be changed to match OMG for example or vice versa, however, i have it on a breadbord, so i simply changed the patch wires):
+^ I2C Module ^ NodeMCU / ESP8266 ^
+| Vcc  |3.3V |
+|GND | GND |
+|SCL |D4|
+|SDA|D3|
+|ADD |N/C (Not Connected|
+despite selecting the WEMOS module we still have to log into the web interface once the firmware is flashed and booted and go to ''Configuration --> configure module'' and then set ''D3 GPIO0 Button 1'' to I2C ''SDA(06)'' and ''D4 GPIO2'' to ''I2C SCL (05)''.
+now you get a new reading every 5 minutes via MQTT. if you want to change this interval you can either do this in the ''my_user_config.h'' file or via mqtt or the "console" in the web interface by publishing this mqtt topic and value:
+  tasmota/sonoff/cmd/TelePeriod 30
+this will set it to 30 seconds
