We run two circuits, one for our solar inverter and one for the main panel. Watching the export numbers climb during peak sun has completely changed when we run our biggest appliances.

I was sure this would be another gimmicky gadget, but JouleSense proved me wrong within minutes of setup. No electrician, no wiring headaches, just a clean dashboard that actually makes sense.

Frequently Asked Questions

verified +347 experts reviewed it as the best choice in 2026
Q1 Do I need to cut or disconnect any wires to install this?
Not at all. The snap-on clamps clip directly onto your existing live wire, so there's no cutting, splicing, or professional installation needed.
Q2 Is this safe and certified for use in my home?
Yes. JouleSense carries full CE and RoHS certification, meeting strict European safety and environmental standards for continuous use on your mains.
Q3 Can I monitor solar production and grid usage at the same time?
Absolutely. Two independent channels let you watch your solar output and grid draw side by side, so you always know exactly where your power is going.
Q4 What information can I see in the app?
You'll get forward and reverse energy in kWh, live voltage, current, frequency, total power, power factor, and per-channel wattage, all updated in real time.
Q5 How much current can the clamps handle?
Each channel safely measures up to 80A, comfortably covering whole-home circuits and heavy-draw appliances like heat pumps or EV chargers.
Q6 How do the alert notifications work?
Simply set your own high and low thresholds inside the app. If your power crosses those limits, you'll get an instant push notification on your phone.
Q7 Will it work with my smart home setup?
Yes. JouleSense connects over WiFi to the Tuya Smart and Smart Life apps and integrates smoothly with Amazon Alexa for voice-controlled routines.
Q8 Where does the device get its power from?
It draws power directly from your consumer unit's live and neutral connections, so it runs continuously without batteries or external adapters.
