What they did
A landlord pointed a Tapo camera at a rental's boiler, exports still frames and uses AI to read error codes on the screen, because the thermostats only alert once rooms are already cooling.
Result (as claimed)
Boiler errors get noticed before the house goes cold; the code is on GitHub.
Tools they used
Cost: Pricing depends on the tools you pick; check each official pricing page.
Set it up
Define the job
Say exactly what you want done and what the agent may and may not do on your behalf.
Share only what is needed
Give Tapo camera the minimum files or access required. Avoid sharing passwords in chat when a safer login flow exists.
Review the plan
Ask the agent to show its plan or draft before it acts, and approve each step that has real consequences.
Check the result
Confirm the outcome yourself (order placed, request sent, document understood) and keep a record.
Copy the full setup prompt
Paste into your agent and it will walk you through the setup, asking before anything that sends, posts or spends.

Ask me 3 short questions about my situation (accounts I have, budget, what I want the output to look like). 2. Propose a step-by-step plan using these tools or cheaper alternatives, with the time and cost of each step. Use official pricing pages; say "check pricing" if unsure. 3.
