Ok, complete newbie with HC2, but a long time electronics builder and semi-coder.

Before i got my HC2 we bought a new house which had a nice out side hot tub, but with a dagerous electrical system.

So, that got rebuilt, and the control of that is now handled by a RPi, some power relay modules and a few sensors. Internet connected and all

However, i would now like to create a virtual device in HC2 to get some data from the tub.

I can (as an example) browse to

and that will return

38.741788

(Not as a proper html-file, it just contains that data)

Now, how the heck do I create LUA to get this data from my HC2, and update a label on my virtual device with this informtation? I goofed around quite a lot the last two nights, bit got nowhere fast..

Any hints?

Thanks!

Thank you all!

I will certainly test this in a while.

RIght now I am back at square one, as i was unable to log on to my HC after a power failure. So, I wnet back to factory defaults.

My new plan is to get a few other things working to get some more grip on how LUA actually works.

The reason i started with the hot tub was the fact that I had not yet gotten the shipment of sensors/switches I was waiting for. So all I had was a Wall Plug and a 2x1,5kW

Hello!

Not as far as I can see. I see nothing logged in the access logs on the Raspberry. But if I do it from my browser, it is of course served/logged as expected, so the HC2 does not seem to call the RPi
