Heating Control for Newbie

I use a pair of Fibaro Relays, my plumber wired them into the existing clock/programmer, so I have the “old” style setup as a backup, and use ST/CoRE to control the heating and hot water, it has been working pretty well so far.

Happy to elaborate more if people are interested as it took me a long while to figure out how to do this, and to find someone that would spend the time/effort to help.

I have been doing a lot of thinking about this. My conclusion is that I’d be better sticking with the existing clock and have the facility to override with a Fibaro relay as Mr mcdermott.st has done. I can always add a smart thermostat.
Mr mcdermott.st, how does your system work. Does the relay allow you to override the clock, ie turn off when the clock is on as well as turn on when the clock is off?

Having gone the Evohome route. I would strongly recommend McDernotts route. You may later wish to go the fully automated route later but in the meantime its a great way to start and likely will be all you need. I guess, as he suggests, its getting a plumber to understand and do what you need.

I’ve now got a Fibaro dual relay to play with. I’ve managed to get it working (thought the 2 relays appear as 1 thing). I’m trying to figure out the logic. I figure I want to be able to override the clock to either turn on or off but the way the relay works out of the box isn’t suitable. I haven’t figured out the parameters yet but I guess there are ones which will make it work the way I want.
Any advice will be gratefully received.

I don’t use the clock at all any more, it is just there if needed for the future.

is it the wiring you need help with, or the setup in ST? I didn’t do the wiring myself, but i can take a look tonight and send some pictures if that helps.

The relays relay should appear as 2 separate switches. so one for each zone or one for heating and one for hot water depending on your setup.

Also take a look at this

I think the problem is that I am using a (borrowed) Fibaro FGS 221 relay and I can’t find a device handler which makes the two switches separate. I might just buy myself an FGS 222 or 223.
Regarding the wiring I can probably figure that out, its the technical stuff I struggle with.
Cheers for the help.

Only just came across this thread and it looks like you have already decided the route you are going to take, but have you looked at Tado.
Fully programmable through its own app and can be integrated into ST to be controlled that way.
Can also integrate into Google Home fo contol.
Probably too late with this post.

Nothing is decided yet, I’m open to ideas. But as I want to keep it simple, basically replacing the timer and having control via Smartthings, just putting a Fibaro relay in seems like the simplest and cheapest option.

By the way mcdermott.st, can you elaborate on the control you use? I’m not sure what CoRE is. I’m basically after something to work as a timer and incorporate a thermostat. I’ve no hot water to control.

See here:

It is essentially just a flexible rules engine, send some s/shots in a separate post about how I use it.

I should add, I also use action tiles, but that just helps to give you a window as to whether the heating is on and to allow anyone at home to boost the heating

Here is a screenshot of a CoRE piston that sets my Tado Thermostat.
You could use something like this to turn on/off the Fibaro relay.
Use a temperature sensor to turn the relay on and off and also set up away modes so that your heating only heats up to, say, 5 degrees. (Frost protection).

All this looks great but I’m struggling getting it set up. I don’t have the Enable GitHub Integration button My SmartApps so I’ve been trying to set up GitHub but it seems complicated. I’ve got myself a bit lost.

You don’t need github to download the app.
Go to github and copy the code.
Log on to your ide and go to my smartapps.
Click on new smartapp, zelect from code and paste in the code.
Click on create and then save, publish, for me.

Thank you. Got it now. I just hadn’t found the code and thought I had to do more.

When you first access CoRE you go into Marketplace, SmartApps, My Apps the click on CoRE.
Once you have done this, on all subsequent occasions you MUST access it via Automations- SmartApps. If you don’t you will have issues.
EDIT. @Itsmeyouknow If you wish to see the dashboard you must enable OAuth in the settings for the SmartApp.

I spent the evening annoying my wife by turning a light on and off with the temperature sensor in the motion sensor. Thank you @mcdermott.st and @bobbles
Is there any other way to program CoRE other than the Smartthings App?

Action Tiles? Can you explain what these are? I’m learning new stuff every day.
