API endpoint to read a station's last reading (for Home Assistant integration)

Hi

I'd like to be a able to read my station data into my Home Assistant system. The most recently uploaded data would be fine.

I could use the web page on: radmon.org/radmon.php?function=showuserpage&user=rjelbert 
... but the page is quite large and would put a lot of load on the radmon.org server if polled on a regular basis

It would be much better to have a minimal response endpoint like this: radmon.org/radmon.php?function=showuserdata&user=rjelbert
... if the response only contained the last reading (and perhaps the date/time it was uploaded) that would be perfect.

I'd be happy to share the instructions on loading the data into Home Assistant when I've done it. Does anything already exist or could it be added?

Thanks very much

R
UPDATE: I used the information provided in this thread and created a Home Assistant radmon.org integration. See: radmon.org/index.php/forum/projects/1252...ation-files-provided

BTW great that you use a Raspberry Pi to host Radmon. I'm a big fan and run lots of things on my Pi 4 server. Here is mine in the case I designed & built. I notice your temp is quite high at 77.4 C . This is quite close to the throttling temp (80 C) so I'm curious to know if you have a heatsink / fan / case for it? My temp sits at 47 C but the case does have two fans!

It runs fanless, and it's summer. So it runs very hot. It's got heatsinks all over it, so it never quite gets to throttling. Without the heatsinks it would be throttling almost immediately! But, even though it's scorching hot, it seems pretty reliable. It is slightly underclocked, I had an early version that wasn't stable at rated clock frequency.
The temperatures probably don't help the SD cards though.

The case did have a ventilated cover, but it restricted airflow too much. So just the base of the case is used to hold the board.

One of those machined heatsink cases with fans would probably be ideal for it...
