Thanks for this review. I've instantly bought one - hopefully the affiliate link does its thing. I have a lot of 3D printers running in a workshop outbuilding, where we will not likely hear the current smoke alarm. A wifi link gives me good options to try to force some sort of integration. I've just plumbed in an 'untrusted' network at home so it can go straight onto that with all the other Chinese devices, Alexa, etc.
