The physical weight of the device, typically measured in grams (g) or ounces (oz).

Weight can be important for installation considerations, especially for wall-mounted or battery-powered devices.

Devices are typically rated using the Ingress Protection (IP) scale, which indicates the level of protection against dust, solid particles, and moisture.

An IP rating (Ingress Protection rating) is a standardized way to describe how well a device is protected against solids (like dust) and liquids (like water). The rating consists of two digits:

- The first digit represents protection against solid particles (e.g., dust).

- The second digit represents protection against liquids (e.g., water).

First Digit (Protection Against Solids):

- IP0X: No protection against solid objects.

- IP1X: Protection against solid objects larger than 50 mm (e.g., accidental touch by hand).

- IP2X: Protection against objects larger than 12.5 mm (e.g., fingers).

- IP3X: Protection against objects larger than 2.5 mm (e.g., tools or thick wires).

- IP4X: Protection against objects larger than 1 mm (e.g., thin wires or small tools).

- IP5X: Dust-protected. Limited ingress of dust is allowed, but it won't interfere with operation.

- IP6X: Dust-tight. Complete protection against dust, ensuring no ingress of particles.

Second Digit (Protection Against Liquids)

- IPX0: No protection against water.

- IPX1: Protection against vertically falling water droplets (e.g., light rain).

- IPX2: Protection against vertically dripping water when tilted up to 15°.

- IPX3: Protection against water sprayed at an angle of up to 60° (e.g., light splashing).

- IPX4: Protection against water splashes from any direction.

- IPX5: Protection against water jets from any direction (e.g., a garden hose).

- IPX6: Protection against powerful water jets (e.g., heavy rain or washing with a hose).

- IPX7: Protection against temporary immersion in water up to 1 meter deep for up to 30 minutes.

- IPX8: Protection against continuous immersion in water beyond 1 meter.

Battery-powered devices typically use standard batteries like AA, AAA, or button-cell batteries (CR2032, CR123A), which are easy to replace and widely available.

Devices that connect via Wi-Fi tend to consume more power due to the constant need to maintain a connection with the network, meaning more frequent battery replacements.

Zigbee, Z-Wave and Thread devices are designed for low-power operation, allowing them to last much longer on battery power, often up to 3-5 years before needing a battery change.

Bluetooth Low Energy (BLE) devices have moderate power consumption, offering a reasonable battery life depending on usage.

A built-in battery that can be recharged without replacement.

Rechargeable batteries are more convenient and environmentally friendly than disposable batteries.

A battery-free button powers itself from the energy of the press: a small kinetic generator inside turns the movement of the key into enough electricity to send the radio message.

It never needs a battery change, which suits a switch mounted where it is hard to reach, at the cost of fewer press types (usually no long press) and a firmer click.

The number of physical keys on the device. Each key can usually run its own actions, so a four-key remote replaces four single buttons.

A single button is the simplest and most portable; multi-key remotes and wall-mounted scene controllers suit a room where several lights or scenes are controlled from one spot.

A dial or ring that turns, read as a continuous control rather than a press.

Turning is the natural way to set a level, so a dial is what to look for to dim lights, change the volume of a speaker or move blinds gradually.

The device detects how it is moved (flipped, rotated, shaken, tapped or slid) and each movement triggers its own action.

This is what a smart cube does: each face or gesture becomes a different command, without any key to press.

The device reports a double press as an action of its own, separate from a single press.

Every extra press type multiplies the actions one key can run: a single button with single, double and long press triggers three different things.

The device reports holding the key down as an action of its own.

A long press is commonly used to dim lights while held, or for an action that should not run by accident, like turning off the whole house.

The device reports three or more presses in a row as further actions.

Multi-tap support is common on Z-Wave scene controllers and on some Bluetooth buttons, and adds actions without adding keys.

The device can raise and lower the brightness of lights directly, with dedicated keys, a hold-to-dim press or a dial.

Without it a button can only switch lights on and off or recall fixed scenes.

The device can be fixed to a wall, with adhesive, screws or a bracket, to work like a light switch that needs no wiring.

A wall-mounted button gives a fixed place to find it, which is what guests and family members expect from a switch.

The device comes with a wall plate or bracket that makes it look like a regular wall switch, often sized to fit over a standard switch box.

Some remotes are sold without it and need a mounting kit bought separately to sit on the wall.

The device attaches magnetically to its wall bracket or to any metal surface.

A magnetic mount lets the button be lifted off the wall and used as a handheld remote, then snapped back in place.

Range: The 2.4 GHz band offers a longer range, meaning it can cover larger areas and penetrate solid objects like walls more effectively than 5 GHz.

Speed: Generally, 2.4 GHz provides slower speeds compared to 5 GHz due to a lower maximum data rate.

Interference: More prone to interference since many other devices (like cordless phones, microwaves, and Bluetooth devices) operate on the 2.4 GHz frequency, leading to potential congestion and slower network performance.

The button can be paired straight to the lights or devices it controls (Zigbee binding, Z-Wave association or the maker's own direct pairing), so it keeps working with no hub or app in between.

This makes the button reliable when the hub is offline, and lets a few lights be controlled without buying a hub at all.

A light on the device confirms that a press was received and sent, and often warns when the battery is low.

Without feedback there is no way to tell a press that did nothing from one that is still on its way.

A built-in buzzer or beeper confirms the press, or can be used as a small alarm or locator.

Some buttons also let the hub play a sound on them, which turns them into a doorbell button or a panic button with feedback.

The device reports its battery level and the app warns before it runs out.

A button that dies silently is one that fails the one time it is needed.
