This is also possible
Use a Homeyscript THEN card, ‘run code and return text-tag’
The result of the code becomes available per the ‘Result’ tag, which you can put in a timeline card or such.
Paste the code below into the card, and run this every day or so.
// Search and display app updates for SDk2 (SDk3 is OK, but SDk2 is deprecated)
let updatesArr = await Homey.apps.getApps().then(f => Object.values(f).reduce((r,b)=>Object.assign(r,b.sdk == 2 ? {[b.name]:b.updateAvailable} : ''), {}));
let appUpdates = JSON.stringify(updatesArr, null, 1);
// timestamp
let SysInfo = await Homey.system.getInfo();
// Extract local time
var localTime = SysInfo.dateHuman.slice(SysInfo.dateHuman.indexOf(' ')+1);
return 'Your SDk2 apps (with available Update):\n' + localTime + '\n' + appUpdates;
Yes it’s my Homey. I don’t believe it gets slow because of many flows.
Look what I did with a 512MB (non)Pro, and it was not dead slow:
