Do I need a C Wire for the ecobee3 to function ? null

Yes. All ecobee smart thermostats require a C wire. If you do not have a C wire you may be able to install with the included Power Extender Kit. Learn more: https://support.ecobee.com/s/articles/Installing-your-ecobee-thermostat-with-the-Power-Extender-Kit-no-C-wire

Yes. If you don’t have a C wire, you can also use an external power supply that you plug into an outlet and connect to the C terminal on your Ecobee. I did this at my former house where I only had an Rc and W wire to the furnace. I found a power supply on Amazon that worked well.
