Yeah, I have come to that realization too. I owe a lot to Cayenne because it was the first app that allowed my existing devices (Pi Charlotte and Charlette) to function.
Home Assistant is certainly more flexible, -but with great flexibility comes great complexity.
Blynk seems to be a "pay to play" solution.
There are several MQTT home automation packages on Google Play- but I haven't seen many that can handle 25 or 30 remote I/O devices well.
I'll need to get a Home Automation package set up soon to replace Cayenne. A "cloud based" solution simply isn't an option. I have NO internet availability in Yorkville. Dang, I gotta make my own electricity (18) 230 watt PV panels, 2 Magnum MS-PAE inverters, ...gotta pump my own well water, ...using LPG for water heating, kitchen appliances, clothes dryer, central heat and generator fuel. WAY off-grid!
My new home passed it's in-wall inspection in mid December. The sheet rock is installed, the walls are now closed up, textured and painted. The HVAC air handler and registers are in, my low voltage wires are tucked behind the wall boxes, ready to be implemented, and the gigabit wires are in. My LV and data backboards are laced. Power supply is installed. I will finish my home with "standard" electrical switches and receptacles, -and retrofit my IoT PC boards after my final inspection (I figure around May of 2017). My next inspection is ceiling fire sprinklers (flow switch test), gas pipe pressure test and smoke/ CO detectors. After that, I'll remove the "temp power" setup and start trimming out my electrical fixtures...then it's kitchen installation time.
If all goes well, it will be one very awesome fully wired high tech residence. I've already turned down 2 offers to buy the property for $1.2M, even as it's not finished yet.
I sure wish Cayenne could have been a part of it.
Cayenne helped me develop my PC boards and test them all, and Adam was the one who suggested I develop PC boards for the Esp12-e. Excellent heads-up, Adam. Thanks.
Using the Pi for home automation is like using a sledge hammer for a fly swatter..yeah, it works, but it's big-time overkill. The cost of a complete Allie or Avonelle is, like, $18 (in prototype quantities), and about $10 if mass produced.
