remote reading of a room thermostat

Hi, not sure if this is the correct forum....

I am looking to remotely read a room temperature.

There is a Mint PC with wi-fi in the room.

This https://www.ebay.co.uk/p/Practical-USB- ... 1655259745 would seem to get the temperature onto the local pc (?)

Any thoughts on how to access this data remotely?

Tony

You must have a very big house? :D

Or I am very lazy !! :D

To clarify my need, I will be leaving my house unoccupied for a period over winter and want to be able to remotely check that the heating is working.

Rgds, Tony

Seems to be a well-known (and Linux-compatible) device: https://www.phoronix.com/scan.php?page= ... inux&num=1.

There's a Python userspace driver available that'll allow you to integrate with NetSNMP: i.e., with a standard method of remotely reading sensor data: https://github.com/padelt/temper-python. I suppose that'll do.

Thanks Rene,

the programming ( at first glance) looks quite involved so might turn into a "project" but also a useful learning experience.

I'm also looking at a RaspBerry Pi which has built in temperature sensor and wi-fi; this also uses Python to access the data and make it remotely accessible.

Thanks, Tony

Note that if that machine will be doing more than temperature sensing it might be useful to open an SSH login on it anyway, in which case you might as as well just login on it and check from the command line...

I would go for the Raspberry Pi option , no contest .

Those things are so darned good ..... rock-solid stability , low power consumption , Debian based OS and easy to ssh into it , at any time .
Here's an example that's near to what you need :-
https://www.rs-online.com/designspark/h ... d-node-red

And so many other great projects it can be used for , eg. Pi-Hole , Pi-phone
The Raspberry Pi Zero W is less than 20 bucks !

Thanks, I think I'm going to give the Pi a try.... is there a Pi forum for if ( when ?) I need help?

You might check this out:

https://github.com/edorfaus/keytemper/wiki

There are actually 3 pages, so look at them all. Page 2 lists devices that actually do work. There are a bunch of similar devices available on ebay and similar sites, you might want to have a look at those, too. I would probably be tempted to have a look at using a Raspberry Pi for this. Might be better than leaving your desktop/laptop running all winter. Yes, they do have a forum:

https://www.raspberrypi.org/forums/

It is a pretty safe bet that somebody is already using a Raspberry Pi for what you want to do. If it can be done with an RPi, somebody is doing it.
