Honeywell is doing a system with radio controlled TRVs that are managed from central console or smartphone. Additional room thermostats can also be added. Central console will switch on boiler when required. No idea about Alexia though.
But IMHO Nest is the best. It has ho radio control TRVs though, but this is not needed if you have manual TRVs that you can configure and forget about. I have 3 zones in the house plus hot water. 3 Nest thermostats control 3 zone valves on s-plan system plus hot water zone valve. Each zone has its own schedule. Wired installation, but wireless is also possible. Installed everything myself. Excellent app.
