Geeni Wi-Fi Smart Wireless Siren Alarm Sensor, No Hub Required, White

I actually bought this as an alarm since it’s so loud, but it works great.. there is a 20 second delay almost when triggered by a window/door sensor thought the smart scene

I have a lot of Geeni equipment this was my first return

Good alarm, low grade app that took some fussing with (I'm pretty good with these too), data is incorrect in the description and manual as it takes 2 batteries and they are not CR2 3V (requires a much larger battery probably a 123 or similar)

Product works great. Was able to use it remotely from my work to wake up my son so he wouldn't be late for school. The only problem is the batteries don't last very long. They last no more than 3 days before you have to change the specialized battery.

I thought it was something you could plug directly into the wall... Nope, battery powered, batteries not included, and they're some weird type of battery. Also, it's too quiet. The alarm sounds weird.

My home security system did not have a siren to activate if alarm was triggered. This is a perfect add on so I can activate the siren through my wireless router as desired.

Tech support told me the wrong size batteries I spent $12 on them. I finally purchased the battery called 123. Another $12 spent because they did not know what size actually fit thier alarm. Easy to setup and operate.

I spent over an hour trying and re-trying to connect this device to wifi and it would not. Kept saying needed 2.4 and to retry. My wifi IS 2.4 and every attempt including manual would not connect it. All my other smart devices had no trouble connecting. Major disappointment.

Muy pero muy buen producto, compre todo (sensor de puerta, movimiento y alarma) todo trabaja bien y su configuración e instalación fue muy fácil y rápida. Solo un detalle, la pila del sensor de movimiento llegó "baja" la sirena suena bien en proporción a su tamaño suena bastante.

Sensor muy Eficiente, sencillo y práctico

No trae batería, esa es la razón por la que solicitó devolución

Está bien el producto, pero no incluye pilas. Trae su cable para conectarla, sin embargo, considero es más versátil con pilas, y son algo complicadas de conseguirlas. Son pilas CR2

Solo tiene nueve tonos y se requiere mucha programación
