Indoor Siren E20 — 110 dB alarm for eufy HomeBase

The eufy Indoor Siren E20 is a wired indoor alarm that sounds at 110 dB to cover an entire floor. It is designed for owners of a compatible HomeBase who want a loud local deterrent. The unit includes a rechargeable backup battery that lasts 48 hours during a power cut and recharges automatically when mains power returns. Installation options are desk placement, 3M adhesive wall mounting or screw mounting.

Mandatory HomeBase compatibility

This siren will not operate without a eufy HomeBase. Supported hubs are HomeBase Mini on firmware 4.0.5.2 or above, HomeBase 2 on 3.4.1.2 or above (units released after 2021), HomeBase 3 on 3.7.2.6 or above and HomeBase Pro on 4.1.4.3 or above. Buyers who cannot update their HomeBase to these versions cannot use the E20.

Simple mounting with one wiring constraint

The package supplies a 6.5 ft power cable, a 3M adhesive strip and screws, so the siren can be placed on a shelf, stuck to a wall or screwed in place. The only common issue is cable reach: the fixed 6.5 ft lead may require a nearby socket or an extension. Once powered and paired, the siren communicates with the HomeBase at up to 656 ft in open air and can be muted with one tap in the app.
