BEWARE - NOT A PACK OF 2
At the time of purchase this was listed as "Shelly 3809511202173 20217 DIY, Pack of 2" however I received only one unit. Thankfully Amazon put this right but the item is available on other listings for £25 as a single and this listing was £39.31 at time of purchase for a "pack of two"

Easier just to put your money in the bin
These are absolute trash. They are infuriatingly slow (response times of 4+ seconds) everytime when they do work. Sometimes they just don't work and don't register a state change at all. Impossible to debug as pressing the "wake" button the device will sometimes connect to your network, and other times it wont. Complete waste of money.
