    Great customer service

    The first device I received wouldn’t answer an Alexa question, ‘Is the door closed?’ with anything but ‘Battery is 100.’ After some discussion about that, the item stopped detecting open and closed altogether. On Jul 24th at 7:51 p.m., the seller offered to send me a new one. On July 25th at 2:56 a.m., I said yes. On July 25th at 3:17 a.m., the seller messaged, ‘I have applied to Amazon for reshipment and I expect you to receive it around July 29th.’ On July 26th at 3:18 p.m., the item was delivered to my front door!
    The new device detected open and closed correctly, although a question about the battery level gave the same answer with new batteries, dead batteries, and no batteries! The inability to determine that batteries are dead (or have been removed) seems to be overall device makeup, as one I have that looks the same but is a different brand with different firmware does the same thing. It reports the last detected status, so, if the batteries die when the door is closed, it will say the door is closed when it has since been left open.
    For this reason, I am using it (and soon my different-brand one) to tell me when I’ve left the refrigerator door or freezer door open and using Ring Alarm detectors for my patio storm door and front gate, as I have three collies, and I need to depend upon correct responses. However, I would certainly recommend these detectors — from seller Gaoducash only — for general use and reminders.

    I haven’t gotten it to work with the app. Until I do, I don’t want to install it on the door. We have a Google Nest system that was working great until the front door sensor stopped working. Nest has stopped making it so I’m trying to replace the front door sensor.

    Never connected. Fail.

    Attempted to connect to my 2.4G router that was about 8ft away. I was using my tablet that was successfully connected to the same router. Excellent signal strength. Double checked password. Tried with both apps. Neither was successful. Returned it.
    I will try a different product from a different company since this one apparently did not do Quality test at the factory to verify it works prior to shipping.

    Bought cheaper ones that work better, but still fits my needs

    I mean, it’s not bad. But it’s not that great either. It works. Connects to tuya no problem. Has a 1-4 second delay on automations. Doesn’t update me on low batteries like other do for some reason? Seems to want to pop off the back and fall off the wall sometimes.
    So for fun it’s great. If you are looking for some tight security, look elsewhere.

    as a Wifi device it doesn’t answer to network monitor tools – I heard it may be SSDP but my net monitors don’t see it.
    The mac address is not documented on the device so can’t verify it. The wifi setup is pretty bad. The initial setup via the app using the instructions takes you to a failure – then it offers a different method which then works. Unlike some 2.4G only devices, this WILL coexist on a network that uses both 2.4 and 5g bands that have the same SSID – a weakness in many chinese products using older chipsets. so 1 positive point for that. The distance from device to Access Point or Wifi router is horrible. fails at 30′ with one wall between. So an Access point in the house with on a garage door fails. The price is fantastic, but in the end, price didn’t matter since it’s not usable. I use Hubitat for my home hub and there are no drivers for it. Some complex Tuya/Tasmota firmware swaps possibly can solve this, but IP devices don’,t play well in most home automations. If your using Alexa only (which is Cloud/external and a poor idea since it’s slow and doesn’t work when the internet is down) it may be this is a good device for certain setups but not mine. I’ve switched to a zigbee device.
