Hi all,
Today I came across a situation where a flow did not work because one of the variables did not work due to a disfunctional app. By restarting the app it came back again, but the situation was such that I thought: “I don’t want to happen that again”. For your information, in this case the Tado app caused the failure and therefore the switch for the floor heater did not switch on on the moment the CV was turned on by the thermostat. Something we could not see or hear, apart from my wife saying that it was still cold in the living room.
Anyway, I tried to setup a flow telling me that the flow caused a failure or did nog run because of an error caused by an app failure. Euhm, so far in vain. Are there any suggestions on how to do this? Preferably in advance, rather than on the moment a flow should be working? Something like “caution, this app causes failure…”
Thanks in advance!

If this is even possible entirely depends on the exact reason why the app failed. Homey isn’t clairvoyant so determining if an app is going to fail will be a nice challenge 
If possible, try and see if Homey is aware if the device is available/reachable. If that’s the case, you can disable/enable the flow(s) for that device.
Maybe also check “Flow with a working quarantee” which is the opposite but with the same function u are asking for.
Thanks for the suggestions. The thing is, the flow becomes corrupt when the app is not responding (for whatever reason). Normally you can see this by testing the flow and you will receive an error message in the flow itself (the exclamation mark, or alternatively the message app is not available). Basically, I would like to use this error message as a trigger to send me a message indicating the flow could not be executed. @robertklep indeed it’s hard to predict if a flow is going to fail. But ‘simply’ picking up that the flow has failed is a step forward (as I can then turn the heat pump manually, so that the heater is not working in for nothing).
I hope this makes it a bit more clear.
Like you say, you need a flow trigger that would be called when a flow fails, but that doesn’t exist. I also don’t think it’s possible for a third-party developer to create an app that would provide such a trigger, because it’s a pretty low-level thing.
You could send a feature request to Athom requesting such a trigger.
Thanks! Nice suggestion, will do as not all automation is as visible as turning lights or TV’s on 
Excuse me but i don’t understand this part image|229x92
Someone can Help me ? That is a Logic with what value ( number ) ? If yes, whitch number about what ?
So, this is a really old topic…does it mean it has been solved? Or did people just gave up?
I am running into the same issues. Complete flows fail, because one of the apps is out of order. Then I restart the specific app, start the flow and things do run smooth.
And I also have cases where the step with the non responding app just doesn’t work and the rest does. Still not what I prefer!
Some of the flows I run have steps in them with “suspected apps”. So, I suspect them not to run well. I have tested just letting them run and yes…it went south. Also tested restarting the suspected apps upfront as they were indicated malfunctioning and then things just ran.
Main question: as Homey is able to indicate if an app is not running well, would it be possible to automatically restart that app? Or can you just (during a nightly run for example) loop through all installed apps and restart them one by one?
Nevermind… found it. Just enabled power user and created a flow
