The above-mentioned features are now live.
As the weather got warmer, it was time to implement support for free cooling.
It may not be all that known to everyone, but Nordic units have support for free cooling using outdoor air when certain criteria have been met. For example the unit enters this mode when the indoor temperature is at least 25 degrees and outdoor temperature is at least 15 degrees. The trigger values are configurable under the advanced settings page of the device.
What happens when this mode starts is that the unit goes to high mode and disables the heat exchange. So basically it will just pump the outdoor air as-is into the house. Note that when this mode triggers, the unit forces high mode unconditionally.
There are flow cards for this mode so you can conditionally reconfigure fan speeds for high when this mode is active if you want to. Or you can ensure that all heaters are disabled so devices donât start fighting each other.
This feature is available as soon as your app upgrades to latest version.
Hei!
FÞrst og fremst takk for en veldig god app som har vÊrt etterlengtet! Jeg har testet litt og har noen tilbakemeldinger pÄ ting jeg har funnet.
Jeg har en Flexit EcoNordic inneklimasentral med luft, varmtvann og gulvvarme. Homey appen fungerer for luft-delen akkurat som et vanlig Flexit luftanlegg. Som forventet er det ikke noe stÞtte for varmtvann og gulvvarme (som er egne faner i Flexit GO appen for EcoNordic sentralen). Er dette noe som enkelt kunne vÊrt lagt pÄ? Eksempelvis endre modus pÄ varmtvann (Eco/Comfort/Boost) og endre temperatur pÄ oppvarming.
Jeg forsÞkte Ä legge til anlegget lokalt ved Ä sÞke etter det, men det fungerte ikke sÄ jeg mÄtte bruke Cloud innloggingen. Usikker pÄ hva som gjÞr at jeg ikke finner anlegget, men mulig det kan vÊre noen innstillinger pÄ nettverket mitt som hindrer dette.
Jeg har forsÞkt Ä endre ventilasjonsmodus pÄ anlegget (Home/Away/High/Fireplace/Cookerhood). Via Flexit GO appen er det mulig Ä velge alle modusene, med unntak av Cookerhood (denne kan kun settes via tilkoblet tilbehÞr). I Homey appen sÄ fÄr jeg opp alle 5 modusene, men jeg fÄr kun valgt Home, Away og High. NÄr jeg forsÞker Ä velge Fireplace eller Cookerhood sÄ bytter modusen automatisk tilbake til den forrige av Home/Away/High. Jeg fÄr altsÄ ikke valgt disse to modusene i Homey appen. Er det flere som har det slik? Er det mulig Ä fikse dette?
Hi,
A reason the device is not disoverable locally may be that it is actually not supported and intentionally filtered out. Seems like the cloud variant is not strict enough.
The reason for it not being supported is that EcoNordic has a different bacnet setup. I.e the controller commands the Homey sends to the unit is not what the unit expects.
Unfortunately, the Flexit docs on this is not reliable and I cannot just blindly add support. To support the plain Nordic units, I had to do a lot of traffic sniffing between the app and the unit, and even create a fake device that the app interacted with.
Would love to fix this, but it is not really possible without access to a unit.
Hi, thanks for this app. Can you add og modify the flow card for ventilation mode to also include optional duration? As example, set fan mode to High with 60min duration. Flexit Go app has this function.
The Flexit Go app is a bit sneaky here. The âhigh durationâ and âswitch modeâ are actually two separate settings that the Go app does in one operation. Meaning if you set High mode for 30 minutes, the next time you change to High using a physical mode button, it will trigger High mode for only 30 minutes as well. For Homey it probably makes sense to expose High mode duration as a setting and make that setting also configurable through flow cards. The same is technically true for similar features in the Go app, such as wait duration before Away mode and duration time for fireplace mode.
Flow and setting for setting High mode duration has now been released.
@marius123 Let me know if this doesnât work for you.
Hi, thanks for your quick response.
I tried to set my ventilation to High directly in the device-setting in the Homey-app. Even though the High duration-setting is 60, it did not return to Home (I waited 2 hours).
Do I have to initiate the High mode through Flow card for the duration-function to impact?
I missed something here. When I tested my implementation I only confirmed that the setting in flexit go matched what I did in Homey.
It seems like there are two âswitchesâ on the Flexit unit for setting high mode. One is for temporary high, and one is for permanent high. The Homey app currently only uses the latter. If this is the case, I will create a new flow card for starting temporary mode too. Homey probably wonât approve an app update until Monday morning.
