AmpByte SmartApp 2.0
Charge When Rates Drop.
Put Surplus Solar to Work.
Keep Home Power in Balance.
SmartApp brings electricity prices, charging schedules and household demand together—helping you charge at lower rates, use surplus solar and keep total household demand within your configured limit for safe charging.
Available on supported AmpByte chargers via Tuya Smart or Smart Life.

SIX SMARTAPP FEATURES. SIX EVERYDAY GOALS.
Start with your day. We’ll show you the SmartApp path.
See the price before choosing the time.
↗02 / Smart ScheduleA lower-rate routine you can see and repeat.
↗03 / Dynamic RateAdapt your strategy to a changing tariff.
↗04 / Solar Only ChargingMake more use of the solar energy you generate.
↗05 / Dynamic Load Balancing (DLB)Use the available capacity without ignoring the home.
↗06 / Visualised StatisticsCompare energy, estimated cost and savings across sessions, months and years.
↗Dynamic Rate: subscription, invited beta access and supported markets. Solar Only and app-based DLB: compatible meter and activated hardware required.
01 / ToU Rate Plan
Your own tariff becomes a 24-hour picture you can edit by touch.
Turn your ToU tariffs into a color-coded 24-hour picture with just a few drags. Define your own prices for Peak, Mid-Peak, Off-Peak and Super Off-Peak.
Drag the side edges of each block left or right to adjust its time period, and the top edge up or down to select the ToU rate type.
Create a Rate Plan for both day types to match your electricity contract. Name and select the plan you want to use.
Timeline colors and cost estimates depend on the plan you enter. Update it when your tariff changes; estimates are for reference, not utility billing.
02 / Smart Schedule · Based on ToU Rates
See prices and charging periods together. Drag block edges to set time and current.
See your ToU price bands behind the charging schedule. Choose lower-rate windows for charging, with prices and timing in one clear chart.
Drag each charging block’s side edges left or right with your finger to set its start and stop times. Drag the top edge up or down to set the charging current.
Save separate weekday and weekend schedules. With Scheduled selected and your EV connected, your charger follows the routine you have chosen.
Leave the charger powered and the EV connected. Use one scheduler: if the car and SmartApp both have schedules, their windows must overlap.
03 / Dynamic Rate
Set a visible price limit. Let Eco Charge follow the changing tariff.
Connect your supported electricity provider and dynamic tariff. View the latest available prices up to three days ahead to spot lower-rate periods.
Drag the red line on the price chart to set your limit. Fine-tune your charging strategy around the rate you are willing to pay.
With Eco Charge confirmed and your EV connected, charging starts automatically when the rate is at or below your chosen limit.
The supplied manual describes a paid subscription feature currently open to selected beta testers. Availability depends on country, provider, account and activated product. Data is supplied through Tuya’s Conow Labs from third-party sources; check rates, currency and any exchange-rate setting.
04 / Solar Only Charging
When your Smart Meter detects surplus solar flowing to the grid, Solar Only redirects it to your EV—so you use your sunshine instead of selling it cheaply.
Your rooftop solar supplies your home first. Send surplus energy to your EV instead of exporting it at a low feed-in rate, reducing the electricity you buy for charging.
A compatible smart meter tracks power flowing to and from the grid. With Solar Only selected and your EV connected, charging starts when enough surplus is available.
SmartApp adjusts charging current as solar output and household demand change. Make use of spare sunshine throughout the day without setting a fixed charging schedule.
Requires compatible meter, charger, firmware and feature activation. Solar Only favors surplus; it does not guarantee zero grid use. The manual describes stopping after grid draw reaches 3 A or more for over 30 minutes, or after the meter remains offline for 10 minutes.
05 / Dynamic Load Balancing (DLB)
The smart meter tracks household demand. Your charger automatically slows down when your home needs more power and speeds up as demand falls—keeping total demand within your configured limit.
Set the supply limit from your main breaker’s current rating. The system applies a safety margin to define the capacity available for your home and EV charging.
A compatible smart meter tracks household demand. Your charger reduces current as appliances draw more power, then increases it as capacity becomes available.
Supported setups connect one Master and up to two Slaves. They share the Master’s configured supply limit to balance charging within the available capacity.
Requires compatible metering, correct installation settings and activated products. DLB manages available current; it does not replace wiring, breaker sizing or required protection. The standalone DLB-A1 monitor is a different system and is not managed in SmartApp.
06 / Visualised Statistics
Energy, estimated cost and savings together—compare each session and see the bigger picture over time.
MONTHLY VIEW
See your monthly totals, then explore each charging session—duration, energy, estimated cost and savings, with vehicle tags to keep your records organised.
Remove the EV connector while the charger is still powered and online. Wait for the record to upload before disconnecting supply power. Cost and savings are estimates based on your Rate Plan.
YEARLY VIEW
Compare cost and estimated savings across the years. See annual energy use, charging time and session totals alongside your lifetime record.
The breakdown shows how cost and savings compare, with your average cost per kWh bringing the numbers into focus.
