The Nestera Automatic Door Opener is powered by 4 x AA batteries.

Don’t worry, this is normal. To preserve battery life, the LCD display is designed to enter ‘sleep mode’ after a period of inactivity. You can ‘wake’ it again by pressing the Menu button.

Please ensure all 4 x AA batteries are new and inserted correctly, and that the battery cable wire is not being pinched between the lid and the box. It’s also worth checking that any connector cables haven’t been accidentally loosened while fitting the unit. If these steps don’t offer a solution, drop us a line at support@nestera.eco and we’ll have you up and running again in no time.

The light sensor is designed to activate the coop door over a gradual light change. This ensures the door isn’t opened automatically in a lightning storm or in car headlights, for example. The sensor takes an average light reading every three minutes to account for this. Please note, if your automatic door opener is positioned near a floodlight or streetlight, this may affect the light sensor. It is best to position your coop away from ambient lighting.

The cord provided with the unit is 1.5m long. Please bear in mind that this includes a small length that needs to remain wound around the spindle inside the unit.

No, this needs to be done manually in the settings. Don't worry, it only takes a moment.
