FAQ
Frequently asked questions
Do I need internet for it to work?
Only to activate the licence and to reach your system from outside your home. Otherwise GridEon runs locally and you open it on your own network (LAN), no internet needed. The weather forecast updates whenever a connection is available.
What hardware do I need?
A Raspberry Pi 4 or an equivalent Orange Pi, a microSD card and a USB–RS485 adapter for the inverter and BMS. The full list is in the docs.
Can I check my system remotely?
On your home network, yes, from any browser. Secure access from anywhere, straight from your GridEon account, is in development.
Does it work with Home Assistant?
Yes, via MQTT. GridEon includes an MQTT broker and publishes data for Home Assistant and other apps.
Can I use one licence on several devices?
Each licence activates on one device. All your licences and sites show up in the same account.
