Zoiinet AK1 Smart Switch Battery Replacement

Dislodge the switch mounting plate from the wall (if applicable -- you may have adhesive on the back or basic screws)

Gently press on the rocker switch from the back of the plate, it should easily pop out.

Using either an iFixit pick or fingernail gently pull apart from the middle of the switch on one side. The switch face should pop off its hinge.

There is an inner plastic plate held in place by 8x plastic tabs (2 on each side). Inset the iFixit pick into each pair, gently wedging/rotating in until the tabs are blocked for 2 or 3 sides. The inner plate should come loose

Note: There is an up arrow indicating the "on" portion of the switch. This matches an arrow on the back of the rocker switch from the previous step

The silicon membrane sits loosely atop the circuit board and the CR2032 battery within. Lift both out.

Use a small screwdriver, pen, or iFixit opener tool and press from the underside of the battery compartment to slide the old battery up and out.

Insert a new CR2032 battery from the top, the positive (+) side should face you

Restore the circuit board and membrane to the inner housing. If all is functional, the On button at the top (up arrow) should flash a green LED when the circuit connects.
