Bluetooth Not Connecting
Common Causes
- •Bluetooth disabled on phone
- •Device too far away (>10m)
- •Device already connected to another phone
- •Device in pairing mode timeout
- •Phone Bluetooth cache corrupted
Solutions
- →Enable Bluetooth in phone settings
- →Move within 5 meters of the device
- →Disconnect from other phones first
- →Power cycle the device (unplug and replug)
- →Clear Bluetooth cache: Settings > Apps > Bluetooth > Clear Cache
- →Factory reset device if nothing works
WiFi Connection Failed
Common Causes
- •Wrong WiFi password entered
- •5GHz network selected (not supported)
- •Weak WiFi signal at device location
- •Router MAC filtering enabled
- •Too many devices on network
Solutions
- →Double-check WiFi password (case sensitive)
- →Connect to 2.4GHz network only
- →Move device closer to router or add WiFi extender
- →Add device MAC address to router whitelist
- →Restart router and try again
- →Try mobile hotspot to test if device WiFi works
Frequent Disconnections
Common Causes
- •Intermittent WiFi signal
- •Router firmware issues
- •Power fluctuations
- •Interference from other devices
- •Device firmware needs update
Solutions
- →Check WiFi signal strength at device location
- →Update router firmware
- →Use a UPS or stabilizer for power
- →Move away from microwave, cordless phones
- →Update device firmware via app
- →Enable 'Auto-reconnect' in device settings
Remote Access Not Working
Common Causes
- •Device not connected to WiFi
- •App not logged into cloud account
- •Firewall blocking connection
- •Cloud service temporary outage
- •Subscription expired (Pro features)
Solutions
- →Ensure device shows 'Online' status in app
- →Log out and log back into app
- →Check if home network allows outbound connections
- →Check Nivoryx Systems status page for outages
- →Renew subscription if expired
- →Try switching between WiFi and mobile data
Zigbee Network Troubleshooting
Device not joining network
Ensure the coordinator is powered on and the permit-join window is open (180 seconds by default). Move the sensor within 2m of the coordinator during initial pairing.
Stale credentials
If the sensor was previously on a different network, factory reset it to clear old credentials. Press and hold the reset button for 20 seconds.
Physical distance / RF interference
Zigbee range is 30m indoors, 100m outdoors. Add mesh router devices (ESP32-H2) to extend range through walls. Keep away from 2.4GHz WiFi routers and microwaves.
Coordinator not ready
Wait at least 30 seconds after powering on the coordinator before attempting to join devices. Check the LED status indicator.
Protocol Selection
The ESP32-C6 supports Zigbee and LoRaWAN, but cannot run both simultaneously due to memory constraints.
Zigbee (Default)
Enabled by default. Ideal for home mesh networks with short-to-medium range (30m indoors).
LoRaWAN
Disabled by default. Ideal for remote locations with no WiFi coverage (range: kilometers).
To switch: Use the Nivoryx app or BLE commands to disable Zigbee, then enable LoRaWAN.
Factory Reset (Last Resort)
If nothing else works, you can factory reset your device. This will erase all settings.
- 1. Press and hold the reset button for 10 seconds
- 2. LED will blink red 3 times
- 3. Device will restart in pairing mode
- 4. Re-add device in app and reconfigure
