A Smarter Smart Controller from Homely?

Toodles · 2025-11-21T14:21:46Z

I received an email from Homely this morning enquiring if I would care to participate as a Beta Tester: ‘Fancy testing a smarter, savvier Homely?’ they said. I’ll let you know how this goes if I am selected in due course. Regards, Toodles.

@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.

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.

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.
