Please use this document as a resource to understand the various parameters on your Blue Series 2-1 switch. We try to keep this up-to-date, but as we constantly change our firmware, there may be a mistake. Please reach out if you see anything that needs to be corrected.

Please see the table below for a quick reference guide to the parameters on the Blue Series 2-1 switch (VZM31-SN). The table is meant to provide a high level view of all the parameters. For a full explanation of each parameter, please click on the hyperlink in each cell to be taken down the page to the appropriate section.

Below we'll list out the parameter number, description, range, default value, size, firmware version it was implemented and an example of how to use it.

AC Power Type is a read only parameter that shows whether or not the switch is in neutral or non-neutral mode.

Switch Mode refers to the switch being in either On/Off or Dimmer mode.

Switch Type refers to the type of wiring installation your switch is in: Single Pole, 3-Way Dumb, 3-Way Aux or Full Sine Wave (FW version 2.11+).

Leading/Trailing Edge refers to the way your switch handles the lights it's controlling. You can switch between each one to get the best compatibility with your bulbs. However, Trailing Edge is only available in neutral single-pole and neutral multi-way with an aux setups.

Smart Bulb Mode is a mode that allows your switch to be used with smart bulbs that are wired to the switch (ie: it locks in full power and sends digital signals to the hub to turn on/off/dim the smart bulb rather than cutting power to the bulb).

To see whether or not your Blue Series 2-1 Switch is in neutral or non-neutral mode, please look for Parameter 21 in your hubs user interface (NOTE: This is a read only parameter that cannot be changed, so it may not show up on some hub user interfaces such as SmartThings).

To change your Blue Series 2-1 Switch from On/Off to Dimmer or Dimmer to On/Off, please select Parameter 258 and adjust accordingly with 0 being Dimmer and 1 being On/Off which is also the default setting.

To program your Blue Series 2-1 switch which installation type it's in (ie: Single Pole, 3-Way Dumb, 3-Way Aux, or Full Sine Mode) you'll want to change Parameter 22 and enter in 0 for Single Pole (which is also the default), 1 for Multi-Way (3-Way) with a Dumb switch, 2 for Multi-Way (3-Way) with an Auxiliary / Add-On switch, or 3 for Full Sine Wave Mode (FW version 2.11 and above).

Internal Temperature Monitoring is a feature that monitors the internal temperature of your switch and will work in conjunction with the Overheat Protection parameter to shut off your switch if it becomes too hot.

Overheat Protection shuts off your switch once the threshold of 90°C (194°F) is met and will return to normal once the switch reaches 70°C (158°F).

Switch Delay refers to the delay between when you press the switch and the light turns on. By default, there is a 500ms delay to account for multi-taps (scene control). In other words, the switch does not turn on right away because it's waiting for a potential multi-tap. You can turn this delay off, but you will lose multi-tap control on the paddle (you will still have it on the config/favorites button).

Local Protection refers to whether or not the load of the switch can be controlled via paddle presses (locally). You can set it so the switch is locked from turning on and off from the paddle.

Remote Protection refers to whether or not the load of the switch can be controlled remotely. You can set it so the switch is locked from turning on and off from your hub's app.

One LED Mode will set your switch to mimic our Gen 2 On/Off switch where only the bottom LED (#1) will operate.

Firmware Progress LED refers to the animation that runs during a firmware update. You can choose to keep this animation on or turn it off.

Disable Relay, "Click" Sound refers to disabling the clicking sound of the internal relay.

Double-Tap Down to Level allows you to set the specific dim level for when you double-tap on the down paddle.

Non-Neutral Output allows you to increase the power output in non-neutral mode. By default the switch throttles the power output in non-neutral to prevent flickering. If you experience flickering when turning this feature on, adjust Parameter 10 (Max Dim Level).

LED Bar Scaling allows you to match the scaling of any Gen 2 switches you have.

Aux Switch Unique Scenes allows you to have different scenes at the aux switch then you do at the smart switch. In other words, you can create a double-tap scene on the aux switch that is different than the double-tap scene on the smart switch.

Binding Default Level allows you to match the default level parameter (Parameter 13 & 14) when using Zigbee Bindings.

Clear Notifications by Double-Tapping the Config/Favorites Button allows you to turn on or off the ability to double-tap the config/favorites button to clear active notifications.

To adjust the voltage output in non-neutral mode for your Blue Series 2-1 Switch, you'll want to adjust Parameter 25. By default, the switch throttles the output of the load in non-neutral mode so that it can effectively communicate with the aux switch (if needed) and/or minimize flickering. When the output is at its maximum, all the power to the switch is taken away by the bulb, which leads to signal instability, bulb flickering and can cause the switch to continuously reboot. You can remove this throttle and test the instability if you want your bulbs to be brighter by setting the value to 1. The default is 0, which puts the throttle on the switch.
​
​NOTE: If you remove the throttle and experience flickering, you can change Parameter 10 (Max Dim Level) until the flickering stops.

Your switch has a built in temperature sensor on its Zigbee chipset that will monitor the internal temperature of the Blue Series 2-1 switch. This will work in conjunction with Parameter 33 (Overheat Protection) in that it will shut off the switch if the internal temperature reaches 90°C (194°F) and will return to normal once the switch reaches 70°C (158°F). This is a read only parameter so there is no default.

Your Blue Series 2-1 switch has built a in overheating protection feature that will shut off the switch if it becomes too hot. When Parameter 32 (Internal Temperature Monitoring) exceeds 90°C (194°F), the Blue Series 2-1 switch will shut the load off, change to On/Off + Full Sine Mode, disable all functionality (you will not be able to control the switch as all buttons will be disabled) and the LED Bar will slow blink red. This notification cannot be cleared until the switch cools down to 70°C (158°F) at which point the notification can be cleared. Please note, when returning to normal state, the switch will not automatically turn on the load, so if you are utilizing Smart Bulb Mode, you will have to set it up again. This is a read only parameter so there is no default.

To adjust the time between when you press the paddle and the light turns on/off, find Parameter 50 and adjust accordingly. A 0 value allows for, "instant on/off" and will turn the light on/off as soon as you let go of the paddle. Please note that if you set the switch to, "instant on/off" it will disable multi-tap scene control from the paddle (you will still have multi-tap scene control from the config/favorites button). The default is a 500 millisecond delay.

If you'd like your Blue Series 2-1 switch to easily turn onto 100% via a double-tap on the up (top) paddle, turn on Parameter 53 (if you'd like to set a specific value other than 100%, then also turn on Parameter 55 and set the level). The default is 0, which has this feature turned off.

If you'd like your Blue Series 2-1 switch to easily turn down to 1% via a double-tap on the down (bottom) paddle, turn on Parameter 54 (if you'd like to set a specific value other than 1%, then also turn on Parameter 56 and set the level). The default is 0, which has this feature turned off.

If you'd like your Blue Series 2-1 switch to easily turn onto a certain dim percentage via a double-tap on the up (top) paddle, turn on Parameter 55 (also remember to turn on Parameter 53 - 2x Up to P55). The lower the numeric value equals a lower dim level (1 = ~1%) and the higher the numeric value equals a higher dim level (254 = ~100%) with the default being 254 (100%).

If you'd like your Blue Series 2-1 switch to easily turn down to a certain dim percentage via a double-tap on the down (bottom) paddle, turn on Parameter 56 (also remember to turn on Parameter 54 - 2x Down to P56). The lower the numeric value equals a lower dim level (1 = ~1%) and the higher the numeric value equals a higher dim level (254 = ~100%) with the default being 2 (~1%).

If you'd like your Blue Series 2-1 switches LED Bar scaling to match your Gen 2 (LZWxx) switches LED Bar scaling, set Parameter 100 to 1. The default is 0, which keeps the Blue Series 2-1 switches default scaling.

If you have your Blue Series 2-1 switch setup in a multi-way setting with an Auxiliary Switch, you can choose to have your Aux switch have different scenes than your Blue Series 2-1. In other words, if you have a scene where you double-tap your Blue Series 2-1 switch to activate a bedtime scene, you can double-tap your Aux switch with a different scene (ie: Movie Scene). The default is 0, which disables this feature and has the Aux switch mimic the Blue Series 2-1 switch (ie: double tap scene on the aux = double tap scene on the Blue 2-1).

If your Blue Series 2-1 Switch is bound to a Zigbee smart bulb and you'd like to set a default level when turned on, change Parameter 125 to 1 (and also set the default level parameters - 13 & 14). By default this parameter is set to 0, which disables this feature.

To disable button presses at the Blue Series 2-1 switch (ie: local at the switch), turn Parameter 256 to 1. By default this parameter is set to 0, which disables this feature. Please note that this is different than Smart Bulb Mode (Parameter 52), which still allows commands to be sent when the switch is pressed locally.

To disable button presses of the Blue Series 2-1 switch remotely (ie: via an app/web UX), turn Parameter 257 to 1. By default this parameter is set to 0, which disables this feature. Please note that this is different than Smart Bulb Mode (Parameter 52), which still allows commands to be sent when the switch is pressed locally.

To mimic your Gen 2 On/Off switch that only had one LED on your Blue Series 2-1 switch, turn Parameter 259 to 1. By default this parameter is set to 0, has the switch mimic the Gen 2 Dimmer switch which had seven (7) led's.

During each firmware update, the Blue Series 2-1 Switch has an animation where the LED Bar will light up to the level the firmware update is at (ie: if the LED Bar is halfway up the switch, the firmware update is 50% completed). If you'd like to disable the Firmware Update LED Animation, please change Parameter 260 to 0. By default this feature is set to 1, which enables the animation.

If you'd like to turn off the audible, "clicking" sound when your Blue 2-1 Switch turns off, change Parameter 261 to 1. By default this feature is set to 0, which enables the has the sound on.

If you'd like to turn off the feature to double-tap the config/favorites button to clear active notifications on your Blue Series 2-1 Switch, change Parameter 262 to 1. By default this feature is set to 0, which enables this feature.
