[RELEASE] *any* hub (C5/C7/C8) Ecobee No Cloud HAP Thermostat (Local) — direct control of an Ecobee thermostat, no Apple hardware

This driver is a different animal from either: it’s a HomeKit controller — it pulls a HomeKit accessory into Hubitat — it’s lightweight, and it runs on any hub. So there’s no memory issue for it to “resolve”; memory was never the constraint here. It’s just software making network connections.

Well aware of that. Homekit controller IS exclusive to the C8Pro on hubitat. That is why I was asking if anyone recalled why. I couldn't find the discussion my fuzzy memory was recalling though. But, I thought it was related to lack of memory on the older devices (the only real differences between the pro and the regular C8 are processing speed and RAM)

This was the only comment I could find on the issue

Used C8

The two big features that you'll be missing on the C8 vs the C8-Pro are the "HomeKit Controller" integration and Z-WaveJS support. The C8 still supports Z-Wave via the older Z-Wave ZIP stack. The C8-Pro has twice the RAM and a faster CPU. The above features require the beefier hardware which is why they are not available on the older model hubs. For a small 30 device system, the C8 should be an excellent choice.

Homekit Controller for C-8 Hub

I bought a Hubitat C-8, and I'm slowly switching over from Google Home. My air conditioning is connected to an Ecobee 3 Lite thermostat, which has homekit compatibility. It looks like the Hubitat Controller app is only compatible with the C-8 Pro. I have it setup on my hub with the ecobee app, but my main reason for switching from Google is local control, and avoiding cloud servers. Is Homekit Controller coming to the C-8 hub?

No, the Pro has more RAM, which was found to be necessary for it to work well.
