Talking of a smarter homely, I was getting too frequent cycling running in smart mode when OAT got below about 6C, they advised me that it was nothing to do with the homely, but that if I changed to standard mode it might help. I did change and it did help. 
I also can’t see any change in efficiency pre and post mode change, so I’m suspecting the whole efficiency thing is a con and it’s only function is weather compensation with a minimum room temp setpoint. 
Im feeling a little cheated as I could have set the weather comp up myself without all the homely gubbings, indeed less complexity is more when it comes to longevity and reliability. In fact the only benefit is the Wi-Fi connectivity for remote diagnosis as I didn’t have a Wi-Fi module on my control system.

@papahuhu I have a feeling that my Homely smart controller is amongst the ‘control group’ rather than running in a new beta test group as I have seen no changes whatsoever as yet. I wonder if the ‘smarter than ever’ version is actually a change to the algorithms that are causing the ‘hot housing’ effects - time will tell. Toodles.

Do let us know the outcome please. 
I have reached the conclusion that the homely ML algorithm isn’t fit for purpose as it stands today, it needs improving.
Given its performance I’m debating wether to insist my installer removes it and refunds the cost and reinstates my system as it should be. It’s a shame as in principle, it should work and self learn. But it doesn’t. 

@papahuhu 😳 Toodles.

I've been thinking of emailing Homely to ask for a few things, if they are beta testing a new system maybe now would be a good time.

Generally I find it works well and have bought a second one for the house we are building as it makes setting the heating so easy. Being too hot at night is easy to fix, switch cool night mode on.  I have decided that paying £25 a year for the system is a good idea as I would like the company to keep running. I do moan at it occasionally but the house temperature is kept very constant. As I am on Agile it does tend to heat more during the night wich means it is hot in the mornings and cooler in the evenings but if I don't want that I can switch on cool night mode and set the morning temperature to where I would like it.  Once I have the battery fitted that is what I will do.

Things I don't like:

I would like more options. I would like to be able to set a high and low temperature for the hot water tank and let homely choose the most efficient time to heat the water. At the moment I think it heats the water up whenever there is a time schedule set even if it is only a few degrees below the set temperature.  That is a feature of the Samsung programming but I would expect Homely to be smarter than that. Maybe I should have teh hot water on all day and see what it does. 

I think the main bug bear is it tends to try to hold the temperature at the highest set temperature all the time even though it allows different times and temperatures to be set. I know cool night mode helps this but I don't think it should be like that by default.

I think there should be a setting to run in the most efficient way and not just go for cheapest, and/or set for best use of clean energy while being efficient, or something along those lines. Cost is still important but running at night when it is only slightly cheaper and running during the day when the HP will run more efficiently feels like it would be a better use of energy and the cost would probably be marginal.

I do find the house is cooler or hotter on a day when the outside temperature changes significantly, it's like it doesn't look ahead or doesn't allow enough for that.  It also seems like it doesn't take the wind chill factor into consideration, and a cold wind has more effect on our house that a really cold day as it is quite exposed where we are.

There are other things I think of at times but I can't remember them at the moment.  Generally I am hapy with how simple it has made it to get a constant temperature without having to spend a lot of time setting up the WC and getting a heating schedule set that works for our house.

certainly is easy, easy for the installer and idiot proof controls for the customer, that is perfect. It also keeps the good temperature control of the room in which the node is placed. So far so good.

But, mine keeps turning on and off. It ramps the heat pump up unnecessarily high, blasts heat into the house and stops. Stop, start, stop start, that’s going to cause massive wear to the compressor and its motor. A heat pump should start up in the autumn and pretty much run continuously until the spring, just modulating up and down rather than on/off. Does yours do the same thing please? Homely is blaming the Samsung controller settings and my installer is blaming the homely, I’m stuck in the middle and unable to know where the fault lies nor how to solve it other than the nuclear option of removing the homely and run it on weather comp instead. It doesn’t help that my installer has recently stopped installing heat pumps too, I was their final install!

@papahuhu When my Homely controller was fitted and installed connected to my Daikin Altherma 3 Monobloc kit, the installer had to re-set the HP (It had been in use for a few months, awaiting the availability of the Homely controller with Daikin integration.) to some basic settings and switch off the WC setting; at that point, the Homely took over and establishes its’ own settings. It took about a week to ‘learn’ my heating requirements but after that, it runs very well. I suspect that Homely might be right and that your heat pump wasn’t set to the default requirements that Homely required at commissioning. I could be wrong of course… Regards, Toodles.

@papahuhu I am attaching the Homely report for today’s performance so far; the heat pump has been gently supplying heat (at ~400-500 watts energy consumption) with hardly a break since midnight. Regards, Toodles.

@johnnyb 

isn’t there a fairly predictable pattern in agile pricing, I’m fairly sure I’ve seen stats that provide average time slot prices over prolonged periods.
Wouldn’t it be an idea to set your water heating according to these stats, then most of the time you’d get the best available prices.

I use cosy, specifically so I have predictable off peak slots, so it’s not an issue. Indeed I don’t think I’d consider running a heat pump if I didn’t have a home battery too, even with cosy. Ours is the double fan 16kW unit, so is hungry for amps, if I didn’t utilise off peak power it would cost a fortune to run. The down side is that it makes no sense for me to use smart+ as the battery acts as the interface between grid costs and heat pump.

@papahuhu Likewise, my heat pumps is much smaller and the maximum draw I have seen is ~2.5 kW though most of the time it is ~1 kW or lower. I’m on Cosy and with 27 kWh’s of Powerwall storage, can ride through the more expensive 16 hours of the day comfortably. Regards, Toodles.

@toodles 

that’s perfect, nothing like mine. Today mine will have started and stopped 3 times every hour. I can tell from the Tesla app that it ramps up to 4kW and back down to zero in less than 15 minutes, then does nothing for 5 minutes and then cycles again. Grrrr.

I watched the installation team install the homely correctly, I don’t know why it’s playing up. I’ll give the installer a few more weeks to sort it and if not I’ll go to their certification body to initiate a formal complaint and investigation. It’s a shame, the mechanical install was perfect, I could fault them, it’s just something is wrong somewhere with the controls. 

thanks for posting it, I still can’t get mine.
