Update

Been using the app as a heating and hot water controller very successfully for quite a while now. When it’s working, it’s very good. Had trouble reconnecting after a broadband router change, but all sorted eventually.

Backwards moves

Despite promises a timed heating option would return (switch on and off on an ad hoc
Basis for a period of time) and be sorted - as we approach Winter - NOTHING HAS CHANGED!!!

Time app developers worked with consumers so you know, apps could be useful and not waste energy (given the enormous cost of it)

I see despite the company “investigating” the below - nothing has been done to bring this option back.

I am wasting money and energy because a really useful feature was ripped out of the app for no reason whatsoever!

Overall - excellent app and controls

BUT removing the option to set the heating for a set period of time under manual settings in the app is really silly (timer function)

It means I end up using more gas - wasting money and energy!




What a ridiculous thing to do.

Bring that option back!

A most esoteric app

As a novice user of a new ASHP, this app seems to purposely make it difficult to find out anything useful. I’m used to the, kind of, ok Hive app with my old gas boiler but this new app gives me no useful information without me reading a manual. Okay, so I can check my system pressure, but I can’t check historical temperature values. I’m not even sure that I can tell if the heat pump is actually running, when it started running and what a forecast of energy consumption might be. The ambiguous glowing display might mean that it’s running; who knows? Needs a big UI upgrade and simplification. A bit of text might help. I’m likely being over critical, but having to consider integrating it into home assistant just to find out how it’s working seems a bit much.

Response from developer

Thank you for your review. We will take your feedback on board and can confirm we are working on ways to make icons clearer. The fully green 'halo' means there is no heating demand. When there is an orange section, this shows the heat pump is heating that zone.

Update

Been using the app as a heating and hot water controller very successfully for quite a while now. When it’s working, it’s very good. Have just, however, had a fairly catastrophic issue in the shape of a new broadband provider and router. Resetting the system and reconnecting, I have just been advised by Vaillant tech support, is (with my set up) an engineer call out. OUCH!!!
