An Alexa shopping list that fills an Instacart cart via Home Assistant

Items added to Alexa land in Home Assistant, are matched to products through the Instacart MCP, and Claude in Chrome finishes the cart for review.

The full story

The owner tracks groceries with Alexa and shops through Instacart. Amazon's official shopping list API had been shut off, but a community integration brings Alexa lists into Home Assistant as to-do lists.

The active items are read over the Home Assistant REST API and matched to products through the Instacart MCP, and Claude in Chrome sets the preferences for out-of-stock items and replacements. A few minutes after saying something to Alexa there is a cart waiting at their store; they review prices and schedule the order themselves, and anything it cannot find is flagged to order elsewhere.

What this is. Real projects where people used Claude to build, fix, port, revive or take apart something, from jailbroken Kindles to rebuilt DOS games, plus the times it went badly wrong. Every build links to where it was shared, and every source is listed here.

How far to trust it. We summarise what people reported and say what each build rests on: a full write-up with code, a short post, or a passing comment. We haven't tested them ourselves. Photos are shown from the original sources with credit. Only modify hardware you own, and back up first.

Privacy. No accounts. Analytics cookies (Google Analytics) only if you accept them; no ads or cross-site tracking. Searches are counted anonymously (just the words) to show what's popular, and so are clicks on Ask Claude (just the count). The Claude connector only receives the search words your Claude sends it.
