Hey @gerard_athom, I’m the developer of the DataVista app, and I haven’t seen any documentation or guidance from Athom about limitations around using the Canvas API in widgets.
I don’t consider myself doing anything unusual, though for some widgets I am using a charting library that might be doing more intensive drawing under the hood. That said, I wonder if this is more about overall dashboard performance — maybe even related to the number of widgets shown at once, or memory management within Homey — rather than a specific issue with the app/canvas api?
I’m already working on shifting more logic to the main app, but if there’s anything else widget devs should consider, I’d love to hear about it. Happy to discuss it here or privately if that works better, as I’d love to fix any issues my app could potentially cause.
