Moneygram and Western Union are not solely the tools of scammers. They provided an international service many years before the major banks got in on the act and began to make it easier (to make more money for themselves).

That is not so much of a disadvantage as may seem.
Most of my remote home automation devices use batteries (AA or AAA) and I don't expect to change them more than once a year - my weather station is still using those it was supplied with back in 2013!

As you have ethernet to each location you could consider using single board or plug type computers with 1-wire Maxim/Dallas DS1820 sensor. RaspberryPi or PiZero would be good choices and plenty of resources online

Another of my unknowns but this time with a flower
Looked to me a bit like Gymnocalycium mihanovichii before flowering but I'd appreciate any thoughts or confirmation please

My simple mind is wondering how all this works

What if a plant, or its offspring, in my collection was brought back from Mexico prior to this legislation (1997?) perhaps by a Victorian or even earlier traveller/explorer/botanist?
