Ecoey WiFi Smoke Detector, WiFi Smoke Alarm with Photoelectric Technology and LED, Smoke Alarm with Test&Silence Function and Low Battery Warning for Home (Not 5G), TUYA APP, FJ158D-H04, 2 Packs

Getting these paired was a royal PIA, but after I finally got the first one then the second was nothing. They are very loud too.

Purchased three of these units in 2022. One for Mom, Dad, and Our home. Today the batteries failed in my unit. I know this because when I walked by the smoke detector it flashed. Indicating the unit needed service. Replaced the Batteries, but it didn't link back up to the Tuya Smart app.When we opened the Tuya Smart app, discovered the app was no longer there. And was replaced with an advertisement for a newer version. (But would not let me open the old app)Upon opening the new Tuya Smart app discovered that all my devices were "off line" and could no longer be used without monthly payment subscription.1. How long has my family been unprotected?2. Was never notified that there was an up coming software change, leading us to believe we were still protected.3. We purchased these units believing that we could use them as any other home electronic device.Whats next?

I bought 6 all together. 1 keeps going off for no reason after about 6 months.

Muy fácil la instalación y muy versátil

Instructions are fairly easy to follow if you have used Tuya app previously. Others may have have issues as the Tuya app is a generic app that connects Zigbee, Zwave and WiFi switches, alarms sensors etc and is therefore easy to choose the wrong type to pair.To pair 1) hold main button until LED light starts blinking, release and look for a second red LED flashing through the plastic 2) in Tuya app press + device then select sensor on left 3) find smoke detector (WiFi) not Zigbee orBluetooth etc. select 4) make sure your phone is connected to 2.4 GHz WiFi router. 5) enter password and it should pair.Battery life appears good after 6 months of use. Test button immediately signals alert in App.

I have worked to connect to the app so I could pair up this set of smoke detectors. I’ve spent so much time trying to make this product to work I am now past the return date and stuck with detectors that will not do as advertised. I need to protect my family and if I have a fire in the back part of the house I need to know. I thought if one detector was trigger they would all alarm but not being able to pair them up I now have a worthless system! DON’T WASTE YOU MONEY OR YOUR TIME!!

Had a tough time getting this setup. Instructions are out of order, follow the numbers. Disable your 5g network if it is named the same as 2.4 first. Hope this helps.

My son was making microwavable Mac & Cheese and forgot to add water. It started smoking in the house really bad. We have 3 of these smoke detectors and none of them went off. These smoke detectors anent any good. They also didn't send any notification to my phone like they are supposed to. Do not buy these smoke detectors.
