Ok, thanks. So trying to get the bits and peaces together from different shops then. I might buy the first set to setup the test environment more expensive then.

Maybe it would be nice to have a forum here where people can post their demand, and order together?

Hi,

I would like to buy my first set of Arduinos and sensors. When I look at the shop here, there are always links to ebay or aliexpress. So far so good, but it either takes 60 days until the peaces arrive, or I have to pay a huge amount for shipping. Might be quicker at ebay but I would also have to pay for shipping. Do you know a shop which ships to Germany and has decent prices as well as a good colletion for sensors and Arduion boards?

Thanks for the replies.

@TimO Can I wireless connect more than one sensor to a Arduino? or just per cable. I found ways to conect more sensore to one Arduino per cable but failed to find a wireless solution.

I will let the Rpi running all the time, but Internet will only be available for 30 minutes a day that I can collect the data.

I do have a better understanding of the setup now. Thanks.

@tbowmo The SenseBender Micro looks great, but for me a little to pricy at the moment. If I built them myself I will save at least some Euros.

I will order some stuff this week and will post about the progress here.

Hi all,

Following situation:

• 1 weekend house which uses up a lot of energy during winter for heating.
• I am 150 km away and cant go there often
• Someone helps to regulate the heating, but more over the thump.
• No Internet connection at house
  -GSM ang 3G available
• 8 points in the house and one outside need to be measured for temperatur and humidity. (Humidity because we want to use carpets and other stuff to isolate the windows and doors and see if the temperature rises and to check that the humidity doesnt go up to much)
• Data needs to be logged, ideally transferred per E-Mail once a day or two.

To realise this project I thought using Arduino would be best. I would like to post my progress on the project here. However, I will also need help to better understand the concept and to get ideas for the best possible solution.

Please correct me if I missunderstood anything:

For each sensor I need a Arduino Board, wireless connector and the sensor itself + powersupply.
I need one Gateway = Arduino Board, wireless connector and powersupply.

So far so good, but How do I collect all the information from the sensors or Gateway? I was thinking about using a raspberry PI to collect and log the information. The Raspberry could run a Webserver where I could download the information from. The raspberry will be connected to a router with SIM-Card, and so save electricity and Surftime I will turn the router on once a day for 30 minutes (Done via a normal plugin timer).

I am currently still struggeling to have the big picture, so appreciate any help and ideas.
