Status and development
What works today, and what we're building now.
GridZeno is up and running: the dongle, the app for iPhone and Android, GridZeno in the browser and the automatic control. Here you can see everything that works today, and what we're building next.
Everything here you can use from the day your dongle is connected. What your subscription includes is listed under prices.
GridZeno Dongle
Local connection to the inverter via Modbus, over Wi-Fi or cable. Updated over the air with signed software.
App for iPhone and Android
Overview, plan, prices, history, control and notifications in your pocket.
GridZeno in the browser
The same overview and the same settings on your computer.
Real-time overview
Production, consumption, battery and grid, updated every 15 seconds.
Danish electricity prices
DK1 and DK2 in quarter-hour resolution, with grid tariff, tax and VAT added on top.
Automatic control
A plan for every quarter hour with four strategies to choose from, and a reason for every decision.
Battery control
Charge from the grid when power is cheap, hold the battery for an expensive evening, and sell when the price peaks.
Stop selling at negative prices
Selling stops when you would otherwise have to pay to sell power, and starts again when it pays.
Limits in the inverter itself
Your minimum and maximum state of charge are written to the inverter, so they hold even if the dongle loses its connection.
Your own rules
Eleven rule types with time windows, weekdays, periods and conditions. With Pro.
Solar and consumption forecast
Several weather sources, physics per solar string and a model that learns your system.
Charts and history
Two years of quarter-hour data, with the forecast laid over what actually happened.
Download your data
Your measurements quarter hour by quarter hour and day by day as spreadsheets that open in Excel, plus your system's details. Under Profile in GridZeno in the browser.
Notifications and reports
Email and push with your own thresholds, and reports daily, weekly or monthly.
Ordering, delivery and returns
Order on the website, get the dongle delivered to a parcel shop or your door, and return it from your profile.
Support
The support button in the app and on the website, and answers from us by email.
Supported inverters
Tested before we sell for them.
Every model on the compatibility list has been tested on real hardware. We only add a new model once it has run on a real system.

Roadmap
What we're building next.
The roadmap is our plan, not a promise of dates. The order may change as we learn more, and as you tell us what matters most.
BetaCan be used now, but we're still building on it.
NowWe're working on this right now.
NextUp next, once the first is in place.
LaterIdeas we want to make real.
Home Assistant and open integrations
Your data should be usable wherever you want it.
Now
Home AssistantThe integration is built: measurements, energy counters, the plan and manual control on every subscription, and prices and solar forecast with Smart and Pro, directly from the dongle on your network. It comes with new firmware for the dongle.
Now
Local access to the dongleRead the measurements directly from the dongle on your own network, bypassing the cloud.
Next
Share data with your installerGive your installer or another energy service access, and withdraw it whenever you like.
Smarter forecasts and control
The more accurate the forecast, the better the plan.
Beta
Battery wear in the calculationThe control weighs the gain against wear, so the battery lasts longer.
Now
Models trained on real systemsThe forecasts learn from systems whose owners have agreed to share data.
Now
A consumption forecast that knows your homeGets to know your home even better: weekdays, weekends, holidays and the equipment you have.
Now
Shading learned from your own measurementsTrees and the neighbour's roof, worked out from when production drops, without you having to measure anything.
Later
Neighbouring systems as weather stationsWhen clouds reach systems to the west of you, GridZeno knows they will reach you soon, and the plan adjusts.
Later
Cloud cover from satelliteShort forecasts for the next few hours from satellite images.
Later
What ifSee what a bigger battery, more panels or a new electricity contract would have meant for you.
More inverters and more equipment
More systems should be able to join, and more of the home should be controllable.
Beta
EV chargerCharge the car when power is cheapest, or on surplus from the sun.
Now
New invertersWe test new models on real hardware and add them to the list one at a time.
Next
More manufacturersFor example Sungrow, GoodWe, Fronius, SMA and Victron. The order depends on what you have.
Next
Several inverters in one systemFor large systems and for those who have expanded.
Later
Heat pumpMove heating to the cheap hours without the house getting cold.
The app
The most important things should be a glance away.
Next
WidgetsState of charge, next action and the current price on your phone's home screen.
Next
Several users on the same systemThe whole household can follow along, each with their own login.
Later
Live Activities and watchFollow grid charging on the lock screen or on your watch.
Later
English and more languagesFor those who would rather read in a language other than Danish.
Business and partners
The same control for larger systems, and better tools for those who install.
Next
Partner portalThe installer's overview of their own customers' systems, with the customer's consent.
Next
Business tariffsPrice calculation with the grid tariffs businesses pay.
Later
Capacity tariffs and peak loadControl that keeps peak consumption down when it costs extra.
Later
The battery on the electricity marketLet the battery earn money by helping keep the grid in balance, pooled with other systems.
Money and climate
More insight into what your power is worth, and how green it is.
Next
Annual reportA year in one place: production, consumption, value and the best days.
Later
CO₂ in the calculationSee how green your power was, and choose to charge when the grid is greenest.
Later
Compare with similar systemsSee how your system performs against others of the same size, fully anonymously.
Hardware and installation
Quicker to set up, and for more kinds of systems.
Next
The dongle finds the inverter by itselfModel and settings are recognised automatically, so setup takes fewer steps.
Next
Self-test after installationThe dongle checks the connection, meter and settings and tells you if anything needs fixing.
Later
Dongle with mobile dataFor systems where Wi-Fi doesn't reach the inverter.
New countries
GridZeno starts in Denmark, but electricity prices swing just as much in the neighbouring countries.
Next
Sweden and NorwayThe same electricity market as Denmark, but with their own price areas, tariffs and taxes.
Later
Finland and GermanyNew markets with lots of solar and variable electricity contracts.
Later
The rest of the EUOne country at a time, each with its own terms of sale and support in its own language.
