Never Overpay for Electricity Again
WattTrim Sentinel reads your Smart Meter data weekly and compares your actual usage against every available plan in Texas, every single day.
If we find a plan that saves you money, we notify you with the plan name, projected savings, and exactly what to do. Your recommendations evolve automatically as your usage changes with the seasons.
How Sentinel Works
Automatic Smart Meter Data
Once you authorize access through Smart Meter Texas, we pull your 15-minute interval data every week. Your usage profile stays current automatically, capturing seasonal shifts without any action on your part.
Daily Plan Comparison
Every day, we compare your real usage pattern against 540+ electricity plans across all Texas TDU areas. Recommendations are always based on how you actually use power, not estimates.
Personalized Alerts
When a better plan appears or your contract is approaching renewal, you receive a personalized recommendation with the plan name, projected savings, and a direct link to take action. You also get a monthly monitoring report to confirm everything is on track.

Common Questions
Do I need to do anything after I subscribe?
Just authorize access through Smart Meter Texas when you run your first audit. After that, Sentinel pulls your usage data automatically every week. Your recommendations stay current without any action on your part.
What if you don’t find a better plan?
You will still receive your monthly monitoring report showing your rate versus the market, usage trends, and confirmation that your plan remains the best option. If we detect meaningful savings before your next report, you will get an alert right away.
How is this different from a one-time audit?
A one-time audit shows you the best plan based on a snapshot of your usage. Sentinel pulls fresh Smart Meter data every week and compares it against every available plan every day. As your usage changes with the seasons, your recommendations change with it. You also get usage spike alerts, contract renewal reminders, and a live energy dashboard.
Can I cancel anytime?
Absolutely. No contracts, no cancellation fees. You can cancel directly through your Stripe billing portal.
What is the Solar Study?
Using your actual usage data, we calculate your ideal solar system size, estimated production versus your consumption, payback period, and 25-year ROI. It is free.
Does this work for solar customers?
Yes. Solar households get everything above plus weekly generation tracking, export credit monitoring, and net consumption visibility on their dashboard.
