Project: get a sms when my electricity falls out

[adriaa]

Homework Statement

I am in my first year electronics/ICT but have already successfully completed several courses about electronics, microcontrollers, programming, fysics...
I have to make a project in my second semester and I am really interested in domotica, so that's why i want to do something about that.
My idea was to give a little domotica touch to a holiday house of a friend:
1. get a sms/or check on a website when the electricity falls out
2. get a sms when the temperature is to low (below 5 degrees) or check on a website the temperature of the house

My ideas of the solution:

I was thinking to put a microcontroller with temperature sensor in his living room, when the electricity falls out, a battery has to take over the microcontroller and has to send an sms.
The microcontroller is connected to a website where you can check the state of the temperaturesensor.

Homework Equations

I know he has a Theben wireless thermostat, is there a way i can connect the microcontroller directly to the thermostat so he can control the temperature from his own house?
Or can i connect the microcontroller to the boiler to archieve this? so the microcontroller takes over the thermostat function?
If the electricity is on i can connect the microcontroller to the internet so het can send the information for the website? any ideas how to do this?
If the electricy falls out i have no internet anymore so i was thinking about sending an sms with an gsm module in the microcontroller. any ideas how to do this?

.1. To detect when the electricity falls out, you can connect a power supply switch to the microcontroller. This switch is connected to the main power supply, and when the power supply is cut off, it triggers the microcontroller to send an SMS or update the website. 2. To detect the temperature, you can connect the temperature sensor to the microcontroller and program it to detect a certain temperature. When the temperature drops below a certain threshold, the microcontroller will send an SMS or update the website. 3. To connect the microcontroller to the Theben wireless thermostat, you can use a serial connection to communicate between the two devices. This means that your microcontroller can control the thermostat, and set the temperature of the house. 4. To connect the microcontroller to the internet, you can use a Wi-Fi or Ethernet connection. This will allow your microcontroller to access the internet and send the information for the website. 5. To send an SMS when the electricity is out, you will need to use a GSM module. This will allow your microcontroller to send an SMS when the power is out.
