Hi,
Please dont take this as a final bid price/time for your project, i just want to be sure what you need first:
Please answer this questions:
1) " logging of multiple temperature / humidity sensors (though of dallas)" :
+ How many sensors?
+ What is going to be the distance from the senors to the pi
2) Please define the relays number and use (all of them) Volts/Amps/ DC or AC
3) Please explain point 5) .... "(requires 220V and a 4 wire connection for the end and start points"
+ is this not just an other relay or need to have sensors for end/start points?
4) You need to define the web server functions/pages with more details.
5) You only as for "he detailed hardware (rpi modules) and wiring instructions what is used", adn that dont include pi power supply and case, only sensors/relays connection to the pi.
6) The pi dont have a Real Time Clock (RTC), do u want to add one? or get the time from the internet connection?
7) Point 6) "rfid" is out of this bid, but we can talk about it if you want.
Thanks
David
