It really has to be battery connected and can't be tethered to the computer, it's too far away. So, can I expect the battery to last a month with this kind of setup? If I'm correct, If I go for a different battery (i.e.. smartphone battery), I'll need the step-down power supply, right? Is it possible to put the Brick in idle mode when nothing is happening to save power? It would wake up then send the notice and then go back to idling... if that's possible...? Thanks!

You, sir, won the most exhaustive answer I've gotten from a stranger. Thanks a lot for taking the time to write it all down! It was yes overwhelming as I'm not into electronics at all. I'm a web programmer so...! So I would need a Master Brick (https://www.tinkerforge.com/en/shop/bricks/master-brick.html) and a Wifi Master extension (https://www.tinkerforge.com/en/shop/master-extensions/wifi-master-extension.html), IO-4 Bricklet (https://www.tinkerforge.com/en/shop/bricklets/io4-bricklet.html) and a Distance IR Bricklet (https://www.tinkerforge.com/en/shop/bricklets/distance-ir-bricklet.html). Do I need both Bricklets or does the Distance IR Bricklet connect directly to the Master Brick? I'll add a Step-Down Power Supply (https://www.tinkerforge.com/en/shop/power-supplies/step-down-power-supply.html) to power it all. I just thought about the time it'll last though... If you say this setup would consume around 100 mAh, if I use a Energizer Rechargeable 9V battery (http://www.energizer.com/batteries/rechargeable-batteries/Pages/9v.aspx) that has 175 mAh, the setup would last not even 2 hours on a single battery? I have a hard time believing this setup would use 100 mAh when my iPhone in standby mode consume about 5 mAh...! Could I just use a 7000 mAh battery (like this one http://www.androidpolice.com/2013/04/12/deal-alert-this-7000mah-galaxy-s-iii-battery-will-power-your-phone-till-the-cows-come-home-and-its-only-34/) and think a 100 mAh setup would last 70 hours (or around 3 days). I know I'm sidetracking the question but... anyway... Finally, about the communication part, when you say the website can periodically query the status of the microswitch, do you mean I could do something like "masterbrick.getStatus();" in PHP and it'll return the switch status? How would I connect to the Brick via PHP? Again, thanks for your time, I really appreciate it!

That sounds very interesting! Let me know if I understand correctly: when the Wifi Extension will be out, I'll just need the bricklet (door sensor) and the Wifi extension plugged to it and it'll send a notice via the Wifi network and it'll get to my PHP script? When is it supposed to be out? Any timeframe? Also, can this solution be powered only by battery? If so, how long should I expect the battery to last? Thanks a lot!

Hey, I'm, just trying to find a simple way to relay the information about a door at home, if it's opened or closed. I tried to understand if the bricklet would help me but I'm not sure what it is actually. Is it autonomus as in could I just check via a Javascript / PHP page that the door is open or closed with the sensor? Thanks!
