Agreed I can do it by asking. Siri turn heating on,Siri turn heating off and can specify a temperature but can’t add a time, so can’t ask for turn heating on at 20° for 30mins but can ask to turn heating on at 20°
My use of my Alexa in conjunction with the "very limited" tado° parameters.......makes my Central Heating "control" surprisingly effective.......I am able to do things that very many tado° users think that tado° should be able to provide straight out of the box.......and we all know that that is just a "pipedream"........and don't get me started on the features that tado° pretend work but are actually "smoke and mirrors" sales gimmicks.........imho
IMO this request should be aimed at Apple not Tado˚, as Tado˚ can't control how Siri works. Apple only recently added the ability to do timed control with lights (Hey Siri, turn off xxxx in 30 minutes), you should request them to add Timed Heating control as well.
