I suspected something like that. My flow should the way it is writen with the change if the card “fail” do a retry every 15 min until the x hour limit have passed in my case the trigger is price highest 2 hour amount between 18-22 so it moves around in that timeframe with 15 min pricing. The limitation lock variable prevent it from dual run if already executed once with success. There is situation where i dont want it to run (future prod prediction check and so on). The morning reset flow have a diff design solution.
Was considering setting up ems and put logging triggers to check the behavior if it is something for me
Makes sense, thanks for laying it out — that’s exactly the case the 1.2.18 fix is meant to support: if the target-SoC write fails, the card no longer runs the battery to the old target silently, so your “retry every 15 min until the window passes” actually has a reliable failure to react to. The lock variable + morning reset pattern is a clean way to do the once-per-day guard.
One thing I’d love to understand: how do you fetch the prices today? I’m looking at adding price-aware charging/discharging to the EMS (solar first, then fill in the cheapest hours toward a deadline), and I want to feed it a price forecast the same way people already have their data.
Concretely:
Which app/source do you use for the spot prices (Tibber, Nordpool, “Power by the Hour”, something else)?
Is it 15-min or hourly resolution?
How does it expose the prices in Homey — a capability you read, or do you build the “highest 2 hours in 18–22” selection yourself in a flow (Logic / better logic), or does the price app already give you a “this is a peak/cheap hour” trigger?
And yes — setting up the EMS device with the trigger logging is a good way to watch it without it touching anything; that’s exactly what that view is for.
Im actualy using homey energi solution with RC changes in the experimental version and cards and variables. I used to use tibbers and prior also used Heating controller app but the built in system homey put in is realy good and even better now with the coming stuff. It is doing hour calc on 15 min changes. I swiched out recently the solcast app to homeys new functions for solar prediction wich is realy useful sinsi it is way more accurate sins i have a west/east system and solcast aint very good on that. Been using homeys new system for it for 2 weeks now and it is realy nice.
