Why Is Inovelli Dimmer Ramp Rate Not Applying?
- Wrong ramp-rate parameter (local vs remote, on vs off)
- Parameter not written to the device
- Confusing ramp rate with dimming duration
Problem Description
You changed the ramp rate parameter on your Inovelli dimmer but the light still ramps at the old speed — or the speed only changed for hub commands but not for paddle presses. Inovelli dimmers have separate ramp rate parameters for hub-controlled and paddle-controlled dimming, and Smart Bulb Mode bypasses the internal dimmer entirely.
Why This Happens in Real Homes
Inovelli ramp rate not applying is often a case of the wrong parameter — there are separate ramp-rate settings for local (physical paddle) versus remote (hub command) control, and for turning on versus off, plus a distinct dimming-duration parameter. Changing one doesn't affect the others, so the ramp can seem unchanged if you adjusted the wrong one.
Identify which ramp you're trying to change (local vs remote, on vs off) and set that specific parameter, making sure it's actually written to the device. Note that a transition time sent by the hub with a dim command can override the device's ramp rate, so check your automations aren't specifying one. Distinguish ramp rate (fade speed) from dimming duration. Update firmware and use in-range values. Setting the correct ramp parameter, and preventing hub overrides, gives the fade you want.
Symptoms
- Ramp rate not applying
- Dim ramp speed unchanged
- Ramp parameter ignored
- Fade time wrong
- Ramp rate won't change
- Dimming too fast/slow despite the setting
- Ramp not taking effect
- Ramp rate stuck
Recognize these? Here's what usually causes it.
Common Causes
- Wrong ramp-rate parameter (local vs remote, on vs off)
- Parameter not written to the device
- Confusing ramp rate with dimming duration
- Hub sending a transition time overriding it
- Firmware issue
- Value out of range
- Config cached, not pushed
- Multiple ramp parameters
Most fixes happen in the first 3 steps.
Do not tune only one ramp parameter when platform uses multiple transition contexts.
Tools & Requirements
Step-by-Step Solution
Check the correct ramp rate parameter
Inovelli dimmers have separate ramp rate parameters for remote commands and physical paddle presses. Blue Series VZM31-SN: Parameter 1 = ramp rate from hub/remote (0-127, in 100ms steps), Parameter 3 = ramp rate from paddle (0-127). Red Series LZW31-SN: Parameter 1 = dim speed from paddle, Parameter 2 = dim speed from hub. If you set one but not the other: the ramp rate only changes for one control method. Set both to match if you want consistent dimming speed from all sources.
Understand the value scale
The ramp rate value represents time in 100ms increments (roughly). A value of 10 = approximately 1 second to go from 0% to 100%. A value of 0 = instant on/off (no ramp). A value of 100 = approximately 10 seconds for a full ramp. If you set the value to 1 expecting a 1-second ramp: you actually set a 100ms ramp, which is nearly instant and may look like the parameter did not apply. Try setting it to 30 (3-second ramp) for a clearly visible change to confirm the parameter is working.
Check for Smart Bulb Mode conflicts
If Smart Bulb Mode is active: the Inovelli switch does not dim the load directly — it sends scene events to Home Assistant (or uses Zigbee binding), and the smart bulb handles its own dimming transition. The ramp rate parameter only affects the switch's internal dimmer circuit, which is bypassed in Smart Bulb Mode. To control ramp rate with smart bulbs: set the transition time in the Home Assistant automation or the bulb's own settings (e.g., Hue transition time, LIFX transition duration).
Test with the physical paddle
Press and hold the paddle up or down. The light should ramp at the speed set by the paddle ramp rate parameter. If it ramps correctly from the paddle but not from Home Assistant: only the hub ramp rate parameter needs adjustment. If it does not ramp from the paddle either: the parameter may not have been applied. Re-read the parameter from the switch (in Z-Wave JS: click Refresh on the parameter, in Zigbee2MQTT: check the device settings). If the read-back value differs from what you set: re-apply it.
Air-gap and reapply if parameters are not taking effect
Some firmware versions require a power cycle for ramp rate changes to take effect. Pull the air gap (bottom of paddle outward) for 10 seconds, push back in. After the switch reboots, test the ramp rate. If it still does not work: update firmware — Blue Series 2.15+ and Red Series later firmware fixed several ramp rate parameter bugs. After the update, reconfigure both ramp rate parameters (hub and paddle) and test from both control methods.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If flickering only happens on dimming, the issue is almost always the dimmer's minimum-load setting, not the bulb — it's drawing less current than the dimmer expects.
Transition UX should be validated separately for manual and automation paths.
This issue almost always looks more complex than it is — the majority of cases trace back to a single setting, a stale credential, or a default that shipped wrong.
- Wrong ramp-rate parameter (local vs remote, on vs off)
- Parameter not written to the device
- Confusing ramp rate with dimming duration
- Hub sending a transition time overriding it
- Firmware issue
