For SPST relays, i might have to keep the pin at +Vcc all time.
I guess atleast 100 - 200 mA is required for a simple SPST relay to get activated.
If I have to use SPST, 150mA * 12 hours is no less.
Am looking at something which can be turned on with a current/voltage pulse as well turned off...

I am planning to do home automation using microcontrollers.
The application has to be power efficient, Normally a +5 is required all times to make the relay close the circuit.
Latching relay seems to be a good option, however, have couple of concerns though
1. I think, it can be only...
