List of parts I just ordered.

:: Generic for all units


3PCS Micro-controller Nano V3.0 ATmega328 5V/16M CH340G board For Arduino
(1 accounting for defect, mounting damage or in the best case scenario a possible additional TX unit)
http://www.ebay.com/itm/141287092498

:: Humidity & Temperature Sensors


Digital Temperature & Humidity sensor SHT15
(for outside TX unit, should work with long wires.
Costs twice an SHT11, likely not justified. But since I am at it and will invest the time, rather try to achieve the best possible quality)
http://www.ebay.com/itm/181192513879


SHT21 Digital Humidity And Temperature Sensor Module
(for outside TX unit, for use with a short wire or will need and I2C extender)
http://www.ebay.com/itm/221685877037


New HTU21D Temperature & Humidity Sensor Breakout Board Module
(limited by short wire or will need and I2C extender, can eventually replace the DHT22 inside)
http://www.ebay.com/itm/251643554884


DHT22/AM2302 Digital Temperature Humidity Sensor
(inside RX unit)
http://www.ebay.com/itm/221546295018


3x Plastic Cover for SHT10 SHT11 Temperature Humidity Sensor SCM
(should fit the SHT15 as well, not entirely sure about the SHT21, we will see...)
http://www.ebay.com/itm/381090103576

:: Pressure sensor


2 x 1PCS BMP180 Replace BMP085 Digital Barometric Pressure Sensor Module for Arduino
(1 as a spare)
http://www.ebay.com/itm/271453913203

:: Solar partion


http://www.ebay.com/itm/121222634881?_tr...EBIDX%3AIT
UVM-30A UV Detection Sensor Module Ultraviolet Ray Module for Arduino
http://www.ebay.com/itm/121222634881


2 PCS AD822ANZ DIP-8 AD822AN AD822 Rail-to-Rail Low Power FET-Input Op Amp
(1 as a spare)
http://www.ebay.com/itm/301222518099

:: RX Unit Specific Parts


2pcs DS3231 AT24C32 IIC Module Precision RTC Module Memory Module
(1 as a spare)
http://www.ebay.com/itm/371071190235


PC Board PCB Mount SMA Female Jack Nut Bulkhead Right Angle Connector new
(since I am a it, will fit the RX with re-transmitting capability for eventual future WD unit)
http://www.ebay.com/itm/261127442621


10PCS 2N7000 TO-92 MOSFET N-CHANNEL 60V 0.2A Transistor
http://www.ebay.com/itm/130963369289

Geeetech 433Mhz Superheterodyne 3400RF Transmitter and Receiver link kit,Arduino
http://www.ebay.com/itm/200974005470

:: TX Unit Specific Parts


3 x 1PC TMP36GT9 TMP36GZ 100%-Genuine New from ADI Low-Voltage Temperature Sensors
(1 for spares 1 for future additional TX unit)
http://www.ebay.com/itm/181092361353


2x 2PCS 433Mhz WL RF transmitter and receiver link kit for Arduino/ARM/MCU Good
(spares and space for a second TX unit)
http://www.ebay.com/itm/381090103576

Hope I got it all right.

Total spent, including shipping, the spares provisioned and the fact I purchased more sensors than actually required: 119,43 USD

Curiously enough, a number of dealers seem to be off on holidays. I guess because of Chinese New Year.

I am still missing a number of the small stuff, which I expect it would be easy to get either from local shops or from Farnell.
