Unfortunately a great many of them use Sodastream’s gas cylinders - after their patent expired and anyone could build a compatible unit - so you might not be able to escape them getting your money when buying CO2 refills, if there isn’t another brand of gas cylinder available where you shop.

Sodastream have released a new cylinder design (with a bayonet rather than screw fitting), presumably to again attempt to kill off the market for home refilling from a larger CO2 cylinder, or use in other brands of machines.

All of that said, I do like my Aarke machine.

Damn, that was a chonky update. 17GB download, 85GB of files touched.

The website also shows a large unpopulated section of PCB near the network jack with “PoE” silkscreened:

PoE built in could make this a very interesting device indeed.

I mean, that depends…

It sounds like you’re thinking of LoRa, another 900MHz radio protocol.

LoRa has similar bandwidth to Zigbee (125kbps), and as you say is designed for low-power devices running on battery. I have PIR motion sensors at home which have used only around a third of their battery after 2 years.

Security cameras seems to be a large target market for HaLow though, where you need a couple of megabits at a few hundred metres.
