For valves I was keen to using Danfoss lc 13. Zwave so no cloud, compared to all the others on the market they are the least ugly. Bought one to test but never proceeded to install on all radiators (moving to a new house soon)
For the thermostat, I’ve bought a BEOK BOT 313W. Has it’s cloud but there is promising HA integration which should work local. Haven’t tested it yet
