Frequently Asked Questions

Within limits. You do not need to be a developer, but you do need a working Home Assistant installation, energy monitoring hardware, and basic familiarity with YAML and the HA interface. On that footing, every step includes:

• Step-by-step instructions with annotated YAML and architecture diagrams
• Copy-paste YAML code (no programming needed)
• Visual examples and dashboard templates
• Troubleshooting guides for common issues

If you can follow a recipe, you can implement the guided steps. Allow time for entity mapping, a dry run, and trace checks; the total depends on your integrations and equipment.

Yes. The active catalogue is for Home Assistant.

Each product lists the entities and controls it requires before checkout. Retired Homey material may remain available to existing buyers, but it is not part of the current catalogue.

Setup time depends on your integrations and how closely your entities match the product contract:

• Energy Data Foundation: read-only sensor and freshness checks — free, no signup
• EV, tariff, heat-pump, and peak packs: mapping, dry-run validation, then controlled activation
• Any control pack: allow extra time when a device uses vendor-specific services or states

You don't need to complete everything at once—guides are organized in stages so you can implement piece by piece over multiple sessions.

30-day money-back guarantee, no questions asked.

If you're not satisfied with any guide for any reason, email us within 30 days for a full refund. We approve refund requests within 24-48 hours; Gumroad then returns the money to your original payment method, which typically takes 5-10 business days.

The refund policy protects your purchase decision; it is not a guarantee of a particular energy or cost outcome.
