How to change de ac_mode parameter without editing the yaml file

[juanjhdez]

Hi all,
I'd like to know if there is a way to modify the ac_mode parameter without editing the yaml file. It is because I have an underfloor system, it uses hot water in winter for heating and cold water in summer for cooling, but it is the same circuit and same electric valves. I want to automatize in HA the change summer mode to winter mode and viceversa.
Thanks in advance for your help!

Same request here. I would like to have a general switch in HA that I can use to change between winter/summer mode.

Hello, latest 2023.7.0-beta2 allows switching between heating and cooling without restarting HA. Please test.
