Yes. The warranty period is shown on each product page, for example 2 years on the LEDs of our aquarium lights. It covers manufacturing defects under normal use, from the date of delivery. It does not cover damage from accidents, water, power surges, incorrect wiring or unauthorised repair.

Call +91 85890 09982, WhatsApp +91 94472 10158 or email iot@btree.in with your order number and a photo or video of the problem. Many issues can be solved over a call. If not, we will repair or replace it under warranty.

No. The sensor and the receiver connect to each other through their own wireless link, so no internet, router or wiring is needed. The setup is done once using a mobile phone app. It runs on a standard 5 V mobile charger or a 5 V power bank.

Fix the sensor unit on the wall facing the bed. Keep the receiver, with its siren and flashing light, in the caregiver's room or at the nurses' station. When the person in bed starts to get up, the receiver sounds the alarm so the caregiver can help before a fall.

Choose by tank length. The 60 W light suits 2 to 2.5 feet tanks, and the 90 W light suits 3 to 3.5 feet tanks, up to 1.5 feet wide and 1.5 feet deep. Both are WRGB lights with an 8000 K colour temperature, designed for planted aquariums.

Yes. The aquarium lights come with a dimmer, so you can set the brightness to suit your plants and fish.

No. The 24 GHz mmWave presence sensor detects only people. Its detection area is divided into 9 zones, and you can switch off any zone where fans, curtains or plants move, using a web page on your mobile phone. It also detects very small movements, such as a person sitting still, which a normal motion sensor can miss.

Products that connect to 230 V mains power, such as the door open sensor with relay, must be installed by a qualified electrician. The bed rise alarm and the aquarium lights only need to be plugged in and fixed in place.

Our aquarium lights are 100% made in India. BTREE is based in Thiruvananthapuram, Kerala, and supports all its products directly.
