In brief our device is going to be temp sensor which communicates with iOS/droid over BLE link through MQTT/MQTT-SN (Preferably). Phone communicates with the cloud over Wi-Fi.
Multiple temperature sensors, located in different rooms, relay temperature information to phone on regular basis. If temperature increases above certain degrees , user gets notified through text and or/email. The device has pressure sensor as well. If you press on the device , it would notify the people you specified on the list when you did initial setup. Just make it clear, there are two ways the notifications will be sent, if temperature increases above certain threshold, or if the device is pressed.
What we are expecting from developer is to make an awesome and responsive iOS and Android APP along with web service so that device can communicate. Please find the attached document for details. We will be responsible for providing the device or sensor tag for final verification.
