All my wifi contact sensors have stopped working in the Alexa app (Device unresponsive) .

they all work fine in the Grid connect app

I have removed device and data and reinstalled them, still not working

I have unlinked the alexa skill and relinked, still not working

Hi @Darr57,

Welcome to the Bunnings Workshop community.

Let me tag our community's resident automation expert @CSParnell to see if he might be able to kick off the discussion and share some thoughts with you.

Thanks,

Jason

@Darr57 have you tried changing the battery at all? Sounds like a silly question but sometimes when the battery level gets to 20% or less they can start doing some strange stuff. Your app may say 100% but don't trust that so many of my sensors have said 100% and then they start to play up and it's low battery.

Start there see how you go.

Other than that can you list the device brand model of the sensor please.

Hi @Darr57

I totally agree with @CSParnell, that would probably be the first thing I would recommend investigating. Testing one with new batteries will immediately tell you if the rest need changing as the new one will immediately link up or activate.

Batteries, all report 100%
All three of them stopped working at the same time so I doubt it's battery, problem

they are working perfectly in the Grid Connect app

but they do not respond and show non-responsive in a Alexa app

Apologies I misread your message, I've tested all the batteries with the battery meter and they all show 95 to 100%

Hi @Darr57,

Let me tag @CSParnell so they are alerted to your reply. If you were able to let us know the brand and model of the sensors that would be of assistance.

Have you tried removing the sensors from the app and re-initiating them?

Hi @Darr57 that's good you've tested the batteries, what model sensors are they?

Are they set to automatic firmware update?

Did Alexa do am update?

Did Grid Connect do an update?

Did anything else drop off connection with Alexa?

@CSParnell,

All firmware is set to automatically update alexa and grid connect where updated recently but they stopped working before that.

@Darr57

Thanks for that, mine are sitting at firmware v 1.4 is that the same?

Another thing you can try is disconnect one of your devices and install another app called SmartLife

Setup your account pair your sensor, connect Alexa and then see if that fixes the issue.

SmartLife is by the parent company of these devices Tuya so it has some other features GC doesn't have.

Give it a go nothing to loose.

Let me know how U go

@CSParnell,

Cheers thanks for that mine are running version 1.4

I did try using Smart Life but couldn't get it to or scan my sensors do you know the procedure or is it just pretty straightforward Auto scan

@Darr57 you will have to do a flash sync on it to pair it, sorry I forgot one thing i just remembered.

Are you 100% Sure they are Wifi and not Bluetooth?

Do you have a Bluetooth hub like below?

My exact sensor as below is Bluetooth

To bring the sensor over into SmartLife you also need to migrate the Bluetooth hub as well otherwise it can't communicate back to your router.

A pain in the Butt I know, I migrated over 80 devices some time ago but SmartLife is much better. More features.

Also is your Bluetooth Hub on and connected? Just a thought? Did someone accidentally disconnect it?

Thanks for that I got them to Link with Smart Life but they show no activity at all they they don't show the door open or close they don't react in anyway

they only seem to work in the Grid Connect app will not do anything in the Alexa app

By any chance do you use them with the alexa app

If so do they still work with your system

@Darr57

Under SmartLife did you bring across the Bluetooth Hub as well?

They need the Hub to be able to communicate to the network and the cloud

@Darr57

No I don't but I use Google Home and the only door sensors that are showing up under google home are my wifi sensors and ZigBee sponsors not my Bluetooth sensor.

@Darr57 I have tried to link those sensors to a different 3 in 1 hub before and they don't work it needs to be the GC BT hub as I uploaded the picture below.

CSParnell

https://www.workshop.bunnings.com.au/discussion/comment/144158#Comment_144158

@Darr57

I just checked again and in SmartLife that type of sensor definitely shows up as 3rd party control for Alexa but not Google as pictured below. So my gut feeling is GC app has a connection issue, SL you need to import the CG Bluetooth hub over.

Darr57

https://www.workshop.bunnings.com.au/discussion/comment/144861#Comment_144861

I'll migrate the hub over and give that a go.

@Darr57

I've got some real strange things going on with my Bluetooth sensors and hubs the last few days, they are working, not working. I have 3 in total throughout the house and they are all being affected and affecting my door sensors, motion sensors.

It maybe a Grid Connect / Tuya issue

Im wondering if they updated the Bluetooth driver
