I am among all those who bought Smarter Coffee 1st gen, waiting patiently to get IFTTT support at some point. I even bought a second identical coffee maker when the first stopped working. Then the upgrade finally came, but only if you buy a completely new coffee maker. The owners of gen 1 will of course not pay €200 only for the IFTTT support, leaving your existing customers in the dark.
So the feature request is quite simple: Honouring your existing customers by supporting IFTTT on the software for 1st gen as well. At least for a small fee.
