I would like to order the product to be build with short documentation and skype/whatsup call around 1-2 hours to talk about project (every additional time which will be needed will be extra pay)
Small device with button (turn on/off), 2 -3 diods and button + nfc or similar technology to change status of diodes with connection to www (via wifi router or 433 mhz and than wifi to website etc)
1. There should be button turn on /off.
2. When button is turned on and connection to wifi/ master device (device can be the router or bridge 433 with wifi connection wo website?) is established than green diode should be active or green diode show blink from time to time showing that device is active or just not show anything because of saving battery (but than it will be hard to say if device is turned on /off at all -good to have proposal from your side here what is best option from battery perspective).
3. When device is turned on and connection to wifi /master device is not established than red diode/all diodes should blink.
4. When green color is active/no diode at all is displayed(up to solution in point 1) and I press button or touch device using another NFC device/card/phone (both button and nfc should be supported)( different technology can be used) than:
4.1 Only red diode is active
4.2. Information is sent from device to router and than though wifi to website and information is displayed there.
5. When red diode is diplayed and I press button or touch device using another NFC device/card/phone(both button and nfc should be supported) (different technology can be used) than:
5.1. Green diode is active or no diode active - up to solution in point 1
5.2. Information is sent to website
6. Website should contains also option to change status of diode.
8. Device should have own power (battery).
9. Device should also have additional diode orange one which can be only turned on/off from the website. When orange diode is active than other diodes are disabled.
I am opened to any technologies , not only wifi. It can be RFID, or 433 mhz !!. In the project it neccesary to have long time battery which you can charge somehow and cost of buliding device later not more than 10 euro/20 euro.
If person who is going to do it sees gaps and have question we can disscuss it.
Apologize once again! Please update offers accordingly to the changes in the description if needed.
