I found this on Aliexpress, NZ$36 approx – multiple sellers with the product

My interest was a device with barograph function. Plenty of devices available with pressure trend, but I specifically wanted a barograph.

Sampling is every 30 minutes for the graph which is a reasonable interval, there is a specific barometer mode where the readings are ‘live’ but not graphed. The barometer seems consistent once it’s calibrated. One issue that has shown up is when there are significant changes in pressure, the graph scale doesn’t change – leaving historic data points ‘off chart’ until they age and exit stage left

Powered by a built in battery recharged via a USB port. Seems to last a while on one charge – mine is over two months and still going strong and showing a full charge. The USB port is charging only, while it would be cool if you could connect and harvest data… maybe another version or two into the future.

OK quality, the only concern is USB port used for charging seems to be floating rather than fixed in place. Reading the manual this could be by design. It clearly isn’t waterproof, maybe splashproof at best.

The device also does altitude / compass / temperature and humidity, plus a time and alarm function. It does have an annoying beep with every button press – nothing in the manual if it can be disabled (doubt it!)

Verdict – interesting device to keep on my desk.
I’ll update as I get to know it a little better!
