I was wonder if homey offer some schedule feature for zone heating ?
I would like to build my own heating zone with temperature sensor and zwave valve on each radiator. Then one relay at the boiler. So when one zone request heat it open the valve and send request to the boiler. Is there a way to do that easily via Flow? Or do I need to do some programming.
I not want to invest in thermostat such Nest or honeywell.
I vaguely remember Athom have previously stated (on slack) that they would not approve an for scheduling, I read that to mean that its something they themselves would like to one day handle. But iâm just guessing.
I donât see why you couldnât use flows to create the same schedule I have running on my Ecobee, what you want to have a close look at is the 'Date & Time" Card, using it in the âandâ column you can have differnt outcomes for different times of day, days of the week, or even seasons.
Thank you very much. In the post it explain more or less hoe to do with flow. So I will give a try.
I will receive my Homey today.
I have some Qubino Relay and some Eurotronic Spirit zwave valve.
Just a bit of my story.
It is now more than 2 years I use Domoticz with Rflink no zwave. Now I would like to have all in one system. So first I took the fibaro HC Lite I use it a week set my zone my valve works pretty good. But you cant send heating demand to the boiler with the schedule program from fibaro at lease on the HC Lite. Also no LUA. I was too restricted and decide to send it back.
Now I go for Homey because of multi protocol, and ability to do lot of things. Letâs see and hope it will be successful.
Again thank you, keep you post when itâs done and working.
What I would do is the following, using the Better Logic app:
When the measured temperature is lower than the requested temperature set a variable like woonkamerwarmtenodig = true and slaapkamerwarmtenodig = true
Then in a seperate flow check if one of those variables is set to true upon a changed status (or every minute or something) and if one of those variables is true, then poke the boiler in whatever way.
This way you can prevent that if one room is at temperature, that the boiler will remain heating the other rooms if required.
The downside to your potential setup, is that you canât use throttling. (Modern boilers with OpenTherm can ignite at 10% or 25% depending on the heating requirement). If you have a system that you can use a percentage of the boiler capacity, you could use room variables to digits. (So woonkamer = 40%, slaapkamer = 20% - Youâd have to experiment what capacity is the golden middle between cost saving and comfort)
Iâm not sure what you mean by schedule time.
The valves I use are temperature aware, so what I basically do is tell the valves to go to a specific temperature.
Flow 1 - 5:
If 07:00 then set variable âGewenste Temperatuurâ to 20
if 09:00 then set variable âGewenste Temperatuurâ to 16
etc.
Flow 6:
If variable âGewenste Temperatuurâ is changed (left column) and variable âAutomatische thermostaat is Trueâ (middle column) then set thermostat to âGewenste Temperatuurâ
If your thermostat valve is not temperature aware, then you could look into something like:
Flow 6:
If variable âGewenste Temperatuurâ is changed (left column) and âGewenste Temperatuur is less than Huidige temperatuurâ (middle column), then (Fire up the boiler and do the other stuff that is required in your setup) (right column)
And no, I donât live near Eindhoven. I live near Rotterdam.
I just noticed that (which I why I retracted my post ) Testing with that now. Iâm currently testing with release 1.1.1
So far it does spit a lot of errors, but it does work. (( errors like "Falied to set thermostat to 19 (invalid_type) )). Iâm not sure when it gives that error though, as it does seem to function.
Great The errors are directly coming from the Homey API when the device is requested to set the target_temperature to a specific value. If that fails (for whatever reason) - the app tries to set the value 5 times with exponential retry time before it âcomplains.â If you are refering to the output in the log, thatâs expected for the retries. If you are talking about the Homescreen (notifications), it means it didnât work (from the persepctive of the API).
I any case, Iâm interested in the logs - started a chat with you on Slack.
Iâm back, after my first attempt I decide to send back my Homey. Yesterday I check and saw the V2 and nice heating zone schedule available. I decide then to get a new homey. I have already install some of my 433Mhz devices. Later next week will try definitely your app Markus. Thank you.
