How to Fix Inovelli Switch Not Reporting Power State
- Reporting not configured (Zigbee bindings/reporting)
- Model without energy metering
- Polling interval too long
Problem Description
Your Inovelli switch is not showing power (watts) or energy (kWh) data in Home Assistant. The power entities may be missing, showing 'Unknown,' or stuck at 0W. Common causes: the reporting interval is set very high (default 3600 seconds = hourly), the power entities need to be discovered via device re-interview, no load is connected, or the firmware needs updating for accurate power sensor calibration.
Why This Happens in Real Homes
An Inovelli switch not reporting its power state splits into two questions: is it the on/off state not updating, or energy/wattage metering not showing? For state, the device's reporting configuration (Zigbee reporting bindings, or Z-Wave association/reporting) needs to be set so the hub gets updates. For energy metering, first confirm your model actually has power monitoring — not every variant does.
Configure or re-establish the reporting: in Zigbee2MQTT that's the reporting configuration/bindings, on Z-Wave the lifeline association and reporting. Re-interview the device so the hub knows what it can report, shorten a too-long polling interval, and strengthen the mesh so reports arrive reliably. Update firmware. With reporting configured and the mesh healthy, state (and metering on capable models) reports to the hub.
Symptoms
- Switch not reporting power state
- No power/energy readings
- State not reported
- Power metering blank
- On/off state not updating
- No wattage shown
- Reporting missing
- State not in the hub
Recognize these? Here's what usually causes it.
Common Causes
- Reporting not configured (Zigbee bindings/reporting)
- Model without energy metering
- Polling interval too long
- Device needs re-interview
- Firmware issue
- Hub not requesting reports
- Weak mesh delaying reports
- Config reset
Most fixes happen in the first 3 steps.
Do not assume old reporting defaults remain after firmware upgrades.
Tools & Requirements
Step-by-Step Solution
Check if the switch supports power reporting
Not all Inovelli models report energy data. The Red Series LZW31-SN dimmer and LZW30-SN on/off switch support power (watts) and energy (kWh) reporting. The Blue Series VZM31-SN dimmer also supports power monitoring. The Blue Series VZM35-SN fan switch does not report power. Check your model against Inovelli's product page to confirm power reporting is a supported feature. If the switch does not list energy monitoring in its specs, it physically cannot report power data.
Configure the power reporting parameters
Inovelli switches do not report power continuously — they send updates based on configured thresholds and intervals. Red Series: Parameter 18 (power reporting frequency in seconds, default 3600 = every hour), Parameter 19 (energy reporting frequency), Parameter 20 (minimum power change % to trigger a report). Blue Series: check the Zigbee2MQTT or ZHA exposed attributes for 'power' and 'energy' reporting intervals. If the reporting interval is set to 3600 seconds: the switch only reports power once per hour. Set Parameter 18 to 300 (5 minutes) for more frequent updates.
Check for the power entity in Home Assistant
Power and energy data appear as separate sensor entities in Home Assistant. Go to Settings > Devices > find the Inovelli switch. Look for sensor entities named like 'sensor.inovelli_switch_power' (watts) and 'sensor.inovelli_switch_energy' (kWh). If these entities do not exist: re-interview the device in Z-Wave JS or reconfigure in ZHA so Home Assistant discovers the power reporting capabilities. If the entities exist but show 'Unknown' or 'Unavailable': the switch has not sent a power report yet — wait for the reporting interval to pass, or toggle the switch to trigger an immediate report.
Verify the load is connected
Inovelli switches report the power consumed by the connected load, not the switch itself. If no load is connected (the switch controls a circuit with nothing plugged in or turned on): power reports will show 0W. If the load is a smart bulb in Smart Bulb Mode: the switch still reports the power drawn by the bulb through its relay since the current flows through the switch's internal shunt. Toggle the connected light on and check the power reading after the reporting interval — it should show the bulb's wattage (typically 8-12W for LED bulbs).
Update firmware for power reporting fixes
Blue Series firmware updates have improved power reporting accuracy and reliability. Early firmware had issues where the power sensor would report 0W or spike to unrealistic values. Firmware 2.15+ improved the calibration of the internal current sensor. Update via OTA in Zigbee2MQTT or ZHA. After updating, the power readings should be more stable and accurate. Note: Inovelli power readings are approximate (±5-10%) — they are useful for detecting whether a device is on or off and approximate consumption, but not for billing-grade accuracy.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If drain continues after replacing batteries, check the event history — a stuck-open sensor or rapid polling loop burns through batteries in days.
Post-update re-interview prevents many state desync issues.
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.
