Bluetooth devices

[TheGreekTechMan]

Hello everyone,

I would like to control our large roll-up doors in several of our buildings. I was thinking of installing Bluetooth switches in parallel with the up and down buttons and then creating an HMI that can run on a tablet that will be mounted on the hilo's that the employees use. Basically, a screen with buttons that when they pick a building, there will be the doors for the building, they will select the door, and then another sub vi will have an up or down button and a stop button, just like the local buttons by the doors. From what I have seen, I know we can use LabVIEW for this.  Has anyone done anything like this? I need some advice on what the best Bluetooth switch to use that works well with LabVIEW. 

Thanks,

Hello, sounds like a good project. LabVIEW will work to make the application. You might want to look into the range before you go Bluetooth, I think it's limited to 30ft. Tcp/ip is a good option, lots of support and many iot devices to choose from.

I am not familiar with such BT switches, so my only advice there would be to see what kind of API they have and how you're supposed to connect to them.

What I will suggest is to rethink whether you want to allow someone to close a heavy door that they can't see. I think that this the kind of action where you want to have the operator right there to see what's going on.

I agree with you 100%. That’s why I’m only going to use Bluetooth. That’s good for 30 feet.

Here is what I’m going to use.

That looks like a nice unit but what I don't see (in my 10 second search) is an API for bluetooth, they only say: 

Bluetooth 
Add devices fast and easy via Bluetooth connection, using the Shelly Cloud App. 

And searching the API says (no results found): 

Maybe you can find something I am not seeing. If you cant find a bluetooth API, you are going to be doing a lot of hacking to get it to work.

Here it is. 🙂

Well, looks like it's time to get coding 👍
