Thanks, I’ll remember that for next time.
I didn’t think of that as i thought this community page would not e structured enough for HA to pick out the Blueprint.
Anyway, I discovered where the Blueprints are stored in HA (config/blueprints) so just copied and pasted the code into a new file in that area. That worked, but as it happens, I discovered a more recent and versatile blueprint for the Ikea Styrbar button with the conventional ‘Import Blueprint’ button.
