Also: The IKEA rechargeable LADDA batteries are rebranded Eneloops, confirmed by multiple tests to be virtually identical in capacity and charge retention.

Sadly there's no AAA equivalent to the simple old square Tradri 0/1 on/off dimmer switches that use the cr2032 batteries. Those old switches are small enough that I could 3D print brackets to mount them in my standard wall covers. The newer AAA devices are all much bigger or try to do too many things.

The RODRET is the AAA version.

Sadly is too big to mount inside a standard 70x70 mm EU wall frame

Thanks for the update. The ones I have are the Remote Control N2 using AAA, and the motion sensors use CR2032.

Last week bought IKEA motion sensor - AAA
