Yes, but sometimes the nearest weather station doesn't provide the most accurate data.

I see: https://www.vaillant.co.uk/homeowners/products/ecotec-plus-25-32-35-and-38kw-832.html Yes, It's a combi boiler, hehe.

No problem at all! If a combi boiler is a boiler + hot water, I think so. Anyway, I have an Ecotec PLUS 236 (not sure right now, but I think it's the exact model).

No, I don't have a hot water cilinder, so I don't need the VR66 module. I just have the VSMART with its gateway.

No, I have an Ecotec Boiler. I'm still tuning the heating curve, but the point is to understand how does it work. I do believe that it is the problem where I live. This link was helpful for me: http://www.hydroheatplumbing.com/resource-centre/what-is-weather-compensation/ I don't know if the...

Yes, yo can do that, of course. The only problem is if in a single moment the external T is above the internal T. Remember that the VSMAR read the external T from internet. In this case, it considers that there is no heat losses and the boiler does not work. I have to say that everything else...

You're right, I have just seen the IFTTT app in Google Play, I didn't know that. In this case yes, I'm afraid it will not work with a different location.

As far as I'm aware, the VSMART doesn't have location sensitiveness, at least I haven't read anything about it. Regarding the other question, I haven't seen it in Spain, but...

I have just talked with Vaillant SAT and he has confirmed that, for moderate weather like mine where there can be a high T span during the day, this could be a great solution: To choose a colder location in the app and tuning the heating curve so that the app thinks that the house is more...

Well, I don't know the demo mode, in the app there is an advanced menu in the settings of the thermostate. You can tune the offset, turn on/off the anticipation and the heating curve, among others. My only problem is when the outside temp is similar to the inside temp. This can be solved...

Yes, in the advanced menu.

As far as I understand, not necessarily. If you live in a cold place, it works fine. I have solved it, at the moment, by setting a colder location. During the next days I will modulate the heating curve to not die burned. Other solution would be to increase manually the setpoint when necessary.

I have improved its behaviour when the external temperature is near the the setpoint. The problem is that sometimes, the actual external T is much lower than the external T obtained by the VSMART, so the boiler doesn`t work at all, even if the internal T is below the setpoint. So, I believe I...

Thank you. I guess that the output T in the boiler doesn't play any role now with the VSMART.

Hi there. I have recently bought a VSMART control for my Vaillant boiler. I feel the weather compensation too intrusive, so that when the outdoor temperature is not too low, the load is very low and the temperature remains more than 1.5 ºC below the setpoint. So, is there a way to switch off...
