What is the best product or system in each of the following areas to get the best integration into Myserver6?
1. thermostat?  Nest? Ecobee? other?
2. Home security system?
3. Sprinkler control system?
4. Whole house audio?
Thanks,

Hi Graydon!
Short answers:
For Thermostat - Venstar (local WiFi)
Security - ELK M1 Gold Pro
Irrigation - myIrrigation Allonis App with supported relays for control
Whole House audio - lots of solutions....Russound, Atlas, Sonos, HEOS, Denon, many more.

Thanks David;

So for Irrigation, I would just use a couple of those Tasmota relays to turn on each zone? That would be very simple to retrofit into my system since I have 7 zones all controlled by one box by the back door at this time.

Yuppers.
I have a LOT of this stuff documented on our new website...just trying to find some time to expose that information in the Documentation link....
Thanx
David

Is there any plan to do something similar for thermostats in the future? I have a couple rules I'd like to implement with my system that isn't easy with commercial thermostats. How about a "MyThermostat" app?

Yes, myServer can get temperature (including multizone temps) from a myriad of places including Z-Wave, Zigbee, GPIO, ESP32, relays etc. And certainly myServer can control relays.  We already have a thermostat "family" structure of commands.  We already have example user interfaces.  The logic of a thermostat in between is something Allonis will be developing. Our interest is we want to offer a clean user interface ie: no ugly thermostat on the wall. And we need to integrate across multiple HVAC systems for RVs / Trucks / Boats / larger residences that are complicated today to use and install with existing commercial products.

In reality, there is enough in the system today that you could "roll your own" thermostat with automation rules and macros and existing drivers and UI.

There was an Ecobee driver for myServer 5.  Cloud based.  But they keep breaking it....so it could be ported to myServer 6 and fixed, but it's disapointing that they can't manage a consistent cloud API (very typical).
