-**So, here we go:**
+===== Harwdare requirements =====
-**Picture 1 & 2:** Here is everything, we could need.
-  * Different pliers
   * Soldering station / soldering iron
   * Solder
-  * 4.7k resistance
+  * Pliers for cutting
-  * Wemos D1 Mini
-  * Wemos Relais
-  * Connecting pins (normally delievered with the WEMOS)
-  * 2x DS18B20
   * Ideally heat shrink tube in different sizes
+  * Wemos D1 Mini (ESP8266; also ESP32 works fine) development board
+  * Wemos Relay Shield (or any relay compatible with your chosen dev board)
+  * Connecting pins
+  ** Normally comes with the Wemos
+  * 2x Dallas DS18B20 waterproof temperature sensor with ~1m wire (36" = 91cm is ok)
+  * 4k7 resistor (4.7k ohms)
+  * USB power supply for the dev board
+  * Power socket for the USB power supple (dirty socket: two red round Abikos + 1m wire + two 3-way Wago connectors)
+  * Enclosure/box for outdoor use.
+  ** For example ABB IP65 junction box ("jakorasia")
+  ** Note: Most likely the 86x86mm junction box is not large enough, 104x104mm or bigger recommended
   * Something to drink

+===== Connecting pins =====
+Connect the connecting pins with each other as shown. You need to press a little bit to connect them completely.

-**Picture 4:**
+===== Dev board & relay =====
-Just check your Wemos D1 Mini (or pro, doesn't matter) and the relais properly. **Just in ONE specific position, the contacts fit together. For example: TX to TX, RX to TX, D1 to D1, D2 to D2, GND to GND (or G), 3V3 to 3V3. Just already check now, and remind, that you need to solder it together in such a way, that there are NO mixed connections (for example RST to TX etc.. That will NOT work and may damage the board!**
+Take a look on Wemos D1 Mini (or Pro, doesn't matter) and the Relay shield. Both have same pin names written on them. You must install them same so that the names match, only one correct way to do it.

-**Picture 5, Picture 6:**
+Start soldering. A good temperature is around 290°C (depending on your solder). If you never solder such small devices, look for an old defective radio, television, whatever and practice first.
-Start soldering. If you never did on such small devices, look for an old defective radio, television, whatever and make there some trials at first. Solder point by point and **ensure by 100%, that there are NO connections between the neighbored things (for example, that D1 and D2 are NOT connected by mistake, by using too much solder). A good temperature for doing it, is around 290°C (depending on your solder).**

-**Picture 7:**
+===== 4k7 resistor & temperature sensors =====
-All done? Good boy! Next, take your resistor and / or if you are not sure, check the resistance with a multimeter as shown. Set it to the resistance mode, connect the cable properly and measure between and after the resistance. If it shows **4.7k**, perfect. Even 4.67k or 4.73k is okay, there is always a small difference for measuring and tolerance. Just ensure always, that it is 4.7k in the end (4700 Ohm).
+Next, take 4k7 resistor. If any doubts check the resistance with a multimeter: Set to resistance mode and measure across the sides. If it shows **4.7k**, perfect. Even 4.67k or 4.73k is okay, there is always a small difference for measuring and tolerance.
-You also can read the resistance by the colored rings on the resistor, just google for it, how the colored rings are counted.
+You also can read the resistance by the colored rings on the resistor as long as you read the correct. https://www.digikey.com/en/resources/conversion-calculators/conversion-calculator-resistor-color-code-5-band
 {{:Picture7.jpg?direct&600|}}
-**Picture8 and Picture 9:**
+On D1 Mini ESP8266 we shall use **pin D2** for temperature sensors. You can also use D5, D6 or D7 (or even D1 if you connected the relay to other pin; D1 Mini Relay Shield defaults to D1 pin). In EPS8266 other pins have special functions which can/will cause problems. Write down the pin number as you will need it later.
-**TODO** CLEAR UP THIS PIN NUMBER PART
-As shown in the wiring diagram, now solder the 4.7k resistor between D2 and 3.3V, at the end, shorten the wire with the pliers.
-I have seen here in this board several versions, where it was (by my wemos-layout) soldered between 3.3V and D7, so I was a bit confusing, why it looked so different.
-The truth is, there are different layouts of this board and you can solder this connector also between other 3.3v and D connectors, just **DON'T use connector DX DX (the pro's, please help me with the numbers, which D connectors weren't possible, I will edit this post!).
+So solder the 4k7 resistor to D2 and 3.3V. Once soldered shorten the legs with pliers.
-!!!The only important thing is, to remember to which D connector you soldered this resistance, you need to edit this one later in the mitsurunner software, otherwise it is NOT going to work!!! Remember AND make a note for yourself!!!
-D2 and 3.3V is always a good choice!**

+Lastly solder DS18B20 sensors' black wire to ground GND, red wire to 4k7 resistors' 3V3 side and third wire (data) on 4k7 resistors' other side which connects to one D data pin.
