WYZE Contact Sensor Microcontroller Interface

This video will describe how to interface a WYZE contact sensor to a microcontroller. This is a very simple way to get your projects connected to the cloud for smart phone notifications.

Hi, this is a really cool hack. Especially since these Wyze devices are now available at Home Depot in the US, makes them very accessible

Helpful video thanks. This hack leaves you tied to the manufacturer's network. Another option would be to set up Home Assistant on a Raspberry Pi and keep everything in house.

Wowsers this is amazing and simple. Thank you!

At 7:54 you say the range of the system is the range of the WiFi. In fact it is also limited by the range of the 906Mhz signal to the bridge in the nearest WiFi camera. Some people have reported they can increase this range by adding a USB extension cable between the Wyze Cam V2 & the bridge module.

Hi, interesting video. I found an interesting article from Wyze Support: "Waiting until the battery dies may result in the sensor being unusable even when the battery is replaced. Replace the battery as soon as you see the "Low Battery" warning.
If a sensor of yours has died and is unable to connect even after replacing the battery, please contact our support team for help." It is a first time I heard such kind of tech. Can you explain the reason behind and how to unlock it? Thanks.

If you're more into locally-hosted home automation, there's a wyzesense python library, and a wyzesense Home Assistant custom integration. If you already have Home Assistant set up, it's not hard to set up HACS, and then download the custom integration (just be sure to check the Github issues page if the receiver stays blue -- there's some stuff you can do to fix it.)

Please list the replacement battery ID (name, brand, Type) and voltage. Thanks

Any idea how far away the sensor can be from the bridge?

Is it possible to modify the 3V coin battery to use power from the nano on the breadboard or using an external power adapter? I don't want to keep changing the battery every year or when it's needed.

How many different sensors can be connected to the WYZE ??

This is great but I feel real stupid watching this. Im a dumb dumb. lol Thank you though lots of posibilities.

Pretty cool hack. Does WYZE have any analog sensors. Can it go the other way from smart phone to controller so I can mess with my kids.

Interesting. But why not just use like a simple ESP8266 D1 mini board that costs about $4 each and totally eliminate the Wyze contact sensor. Super easy to Flash it with ESPHOME and send your data through your local WiFi. In my case to Home Assistant. These ESP boards support both digital and analog inputs. This way you eliminate the the weakness of the Wyze Sensor's that were long ago discontinued because of reliability issues and the fact if the battery goes dead in one they will get be ruined or bricked. Also better to stay off the Wyze Eco System. Run everything local.

El. hobbyists who get excited about gizmos such as Wyze - and who don't have a smartphone - are advised to research hard and long to see if said gizmo will be accessible without apps, phone and some cloud broker. Further, don't think the cheap gizmo you want will work without a smartphone even if it claims to work with desktops or local LAN. The two "security cams" I bought both refused to even CONFIGURE without a smartphone. Until I can crack both open to see if there are headers available for direct hardware communication, my money (and significant time) has been wasted.
