@johnnyb Might be worth checking that a pump change will help. All I know is that my variable speed pump always runs at the same flow rate whenever I’ve checked it, it is the outlet flow temp target that varies. The only time I’ve seen a lower flow rate is during defrosts.

Is that a PWM pump?  That is what I should have had fitted and they are finally going to change it over. The Samsung mimms unit should then vary the speed to run it efficiently. 

@johnnyb 

I think so. It’s a UPM4xL that takes its speed control from the Samsung control unit. I’ve never seen it vary during space heating. I wonder whether it would vary if the homely wasn’t in a supervisory capacity, but just my conjecture. Could also be that my homely only just started working correctly yesterday. I’ll keep an eye on it the ne t few days and let you know.

I’ve checked and now the pump inverter does vary by a few %.

It most definitely never used to, so must be linked to the previous fault status. I have no idea where the logic to do so originates, be it homely or Samsung. 

My understanding is Homely sets the target flow temperature and switches the heating or DHW on or off. The Samung controller carries on as it was set up to run and does everything else so I would expect it to be the HP controls adjusting the pump speeds etc.

@johnnyb 

I don’t know any better to concur or disagree. Wouldn’t it be nice to know for sure so that if things go wrong we have a chance of understanding what and why, instead of floundering in bemusement and frustration.

But they are wrong, I still can’t see my data via connect, I’ve tried on iOS and desktop, my son even tried via Linux but nowt. It must be some special access that homely set up for you.

None of us were wrong about the method of access and toodles does not have any special access set up. Many homely customers who follow the same steps can then login on a desktop to view the dashboard, so we can't all be incorrect? You just aren't setting it up correctly to get access. Do you have the permissions set to allow for third party access in the 'customer' app? Are you then linking the hub in the installer app? 

In fairness it sounds like it will tell you what you already know- homely doesn't necessarily do slow and steady all the time and will randomly shoot up to max flow temps at random times. Of course, you have no control over what the max flow temp is without emailing them and asking them nicely to change it.

No idea why mine doesn’t work, all I see on homely connect is a map of the world and some search terms, none of which comes up with any heat pumps. I’ve tried it on iOS and desktop, both were the same outcome.
I don’t care so much now because the homely and the heat pump are working correctly, actually brilliantly, for the first time since install. I did a hard reset on the outdoor unit (I was attempting to reset the modbus) and it sprung back into perfect control. It’s weird, it’s hugely quieter too, but I have no idea why that might be. 

@papahuhu I received an email from Homely today and the opening paragraphs said:

Many of you have told us you’d like to see more information about how your system is performing in the Homely app. So, we’re exploring how we can share system performance data - and we want to make sure we get it right.

This short survey is all about understanding how you feel about data, which types of information you’d find genuinely helpful, and what matters most to you.

Your answers will directly shape what we build next and how we share it.It should only take a couple of minutes, and it’ll really help us make sure we’re building the right thing, in the right way, for you. Thanks for helping us make Homely even better 💚

Looks as though our requests for the pertinent performance data might be being listened to after all. The form went on to ask what features we would most like to see. Regards, Toodles. 

@toodles Hi. Yes, I received it too. However, it didn’t include what I really wanted which was system primary data. I can already obtain all the items on the homely list from my control interface. But, it would be handy to get my COP data without a trip to the garage I guess. 
My system continues to behave itself very nicely back on smart mode, you wouldn’t believe what a difference it makes. I don’t care so much about the data now it’s working well, it’s only useful if investigating a fault condition.

That's the point though isn't it. You don't necessarily know when you are going to need the data to diagnose a fault, or indeed understand how (or if) homely is optimising your setup. Do you really want to be relying on your installer for the life of your system? Is that even possible if they don't install heat pumps any more.

As said the dashboard won't come up with anything unless you have linked the hub via the installer app, and allowed 3rd party access.

@benson I did all that stuff, sorry, but it didn’t work for me. 
I did contact Homely and they have offered to transfer the access to my installer account, but that deletes the access of the actual installer and relieves them of their warranty obligations. 
I’ve no idea how you did it, but homely have confirmed it’s certainly not possible for me to do. Perhaps mine is a running on a revised firmware?
