Never Overpay for Electricity Again
WattTrim Sentinel watches the Texas energy market so you don’t have to.
We scan hundreds of plans daily using your actual usage data. If we find a plan that saves you more than 5%, we’ll email you — with the plan name, savings amount, and exactly what to do.
How Sentinel Works
We Store Your Profile
Your usage pattern, service area, and current rate are securely saved when you subscribe — no re-uploading needed.
Daily Rate Checks
We check the Texas energy market every day and compare rates against your current plan — so nothing slips by.
Monthly Heartbeat Report
Every month you receive a personalized report — your rate vs. market trends and usage insights. If a better plan is detected sooner, you get an early alert. We’ll also remind you before your contract expires so you never slip into an expensive month-to-month rate.

Common Questions
Do I need to upload my data every month?
No! We store your usage profile at signup. You only need to upload once. You can upload new data anytime to update your profile.
What if you don't find a better plan?
You'll still receive your Monthly Heartbeat Report showing your rate vs. the market, usage trends, and confirmation that your plan remains the best option. If we detect savings over 5% before your next report, you'll get an early alert right away so you can act on it.
Are audits really included?
Yes. Monitoring subscribers can run unlimited audits at no extra cost. Just enter your subscription email on the upload page.
Can I cancel anytime?
Absolutely. No contracts, no cancellation fees. You can cancel directly through your Stripe billing portal.
How is this different from a one-time audit?
A one-time audit shows you the best plan right now. Sentinel watches the market continuously with daily rate checks, a Monthly Heartbeat Report, early alerts when a better plan appears, and contract expiry reminders so you never accidentally slip into an expensive month-to-month rate.
What's the Solar Feasibility Study?
Using your actual usage data, we calculate exactly how many solar panels you'd need, estimated production vs. your actual usage, payback period, and 25-year ROI. It's $17.99 for non-subscribers — but free for Sentinel members.
