Hot water on combi boiler

Options
I recently had the Tado Starter Kit with Hot Water extension installed to my Alpha EcoPlus combi boiler when I was having my annual service.
The heating side works fine but I’m having issue with hot water.
I’m aware with a combi hot comes on when I turn on the tap, my issue is with the temperature.
The temperature is now a luke warm or little warmer than that at best but it is no where near as hot as it used to be.
I have turned the hot water setting on the boiler to max but the temperate hasn’t changed.
Can anyone recommend anything else I can do as the customer support hasn’t been very helpful.

Note: it has been wired as per the instructions, single relay.

    @GrayDav4276 I have checked all over the app and there’s no hot water option available

    @GrayDav4276 okay thank you.
    It’s been installed under the single relay option on the installation manual as it’s a combi. Would you know what it needs to be installed as instead or shall I try Customer Support again?
    I’ve seen on here that sometimes you have to ask Tado to add the tile onto the app as it sometimes doesn’t automatically go on

    I elected to fit a wired thermostat because I have a Combi. What are the benefits of fitting Tado Hot water control when the boiler acts upon demand for hot water?

    @GrayDav4276 thank you. I’ll try them again. Hopefully they understand completely this time.

    @Melinaajw if you have a combi with Tado installed on relay you won’t get a hot water control. Tado will also have no influence on the hot water setting, it will be controlled by your boiler. Check your boiler manual.

    @WillYZF if you’re using a wired thermostat there won’t be any control of the hot water unless it’s a digital connection, in which case on an Opentherm connection you should be able to set the hot water temp. Not sure if this happens on an ebus connection too.

    @johnnyp78, it was never my intention to have any control over hot water via Tado. Hence my earlier comment.
