We have known the Osram Smart Plug for years as an inexpensive accessory for the Philips Hue Bridge. The Innr SP 120 was added around a year ago. This smart plug mainly scores with its form factor. It is smaller and more compact but also adds a higher price tag.

The Hue Smart Plug can be controlled via Bluetooth without a bridge and can also be used in HomeKit when actively connected to the bridge.
