Hi, i am using a qubino plug to load my phev with 220V at 0:00 with homey bridge and cloud only. I want to detect when the car is full, e.g. when the plug changes power usage to less than 2 watts for more than 2 Minutes. Ideally I would use a countdown timer for this, but i am shocked , homey beta does not even support such a simple thing as a a countdown timer. Any ideas how i could detect when no more power is needed and i can switch off my smart plug ? I mean it is a very simple requirement like detecting when the ebike is full, detecting when the washing machine is done and so on. explain the working of specific Flows in homey. ---

For homey pro there are countdown timer apps, unfortunately not for bridge. Does bridge have flowcards to start/stop flows and logic variables? If so, i think a solution based on these must be possible. ---

Thanky for your reply, yes, my bridge does support starting other flows and setting logic variables. But I do not see a way to use them to find out if the power usage after 2 minutes is still below 2 Watts. Do you have any rough hint how to use these tools to get t working ? ---

Well something like this: First flow detects if powerusage is changed and below 2w. If so, starts a second flow with 2 minutes delay. Second flow, if started, checks is power usage is still below 2w. If so, execute next actions you want. You can enhance this with a Boolean logic variable, set this to true in first flow, and set this to false in another flow if powerusage changes above 2w in the meantime of the 2 minutes. The second flow can check on this Boolean also before executing the next actions. ---

Wow, this works.Thanks so much for the idea. To start another flow with a delay is really a working method to implement some sort of timer logic. ---

Great 👍🏻, Be careful not to start the second flow to many times. So to trigger it only once.
