Single phase AC active power energy measurement

hi all

i have built 1 home automation unit. i'm using arduino + wifi+ relay unit+ fan regulator+ led dimming + rgb led colour changing.

now need measure ac electrical power in each channel , make statical record on web cloud.

i can make these coding. need regarding  selection of energy metering ic.

i have search ic's not able decide 1 can go with.

i going bulk manufacturing product. can add relay module should have measuring ic. should measure how power flowing through each relay when ever turned on.

please suggest me ic.

i'm not worried accuracy. tamper proof. need simple energy measurement.


please replay.

are these low voltage devices, e.g. 12volt, or want measure mains power.
for low voltage devices, measure current e.g. high side current sensor. , calculate power.
measuring mains power lot more complicated.
