HelioPulse is a local dashboard that brings inverters, batteries and EV chargers from different brands together. It runs on a Raspberry Pi, in Docker or in Home Assistant, and keeps working without Internet.
Energy flow
Instant powerUse a USB–RS485 cable, the inverter's own Wi-Fi logger, or a wireless ESP32 collector you flash from your browser.
Flash HelioPulse OS to a Raspberry Pi, or run it in Docker or Home Assistant. On the Pi, a guided portal finishes setup with no SSH.
Watch the energy flow live, get alarms, automate loads and generate reports, all on your local network.
Highlights from versions 1.19 to 1.23.40. Each release links its full notes.
Connect Claude, OpenAI or an Ollama on your network with your own key. The chat answers with your real data, remembers earlier conversations, reads photos and PDFs, and proposes changes you apply with a button. Nothing is sent until you turn it on.
A local MCP server lets Claude, ChatGPT, Cursor or any MCP client query your installation with a token you create. It also works through remote access.
A flow can change a writable inverter setting, such as grid charging current or a time slot. It is off by default: you enable it per device and parameter, writes are rate-limited and each value is confirmed by reading it back.
Group 2 to 9 inverters into one system with a shared or independent battery bank, including Modbus shared buses and Voltronic groups over USB.
Schedule full recovery backups and upload them automatically to Google Drive, Dropbox or OneDrive.
Time-of-use rates and export pricing in the savings calculation, also for off-grid sites without a grid meter.
Control Tuya devices over the local network or the cloud, and Shelly Gen2+ directly on the LAN, as automation actions.
USB-RS485 adapters with a setup assistant, and remote access at https://<name>.heliopulse.io without opening router ports.
Entities named like the dashboard, controls for every writable parameter, and batteries and EV chargers imported as their own devices.
Huawei SUN2000, Victron GX, Deye/Sunsynk single-phase, Sungrow and Solis string inverters, EG4, MUST and Felicity Solar.
A commissioning window to edit drivers, updates the owner approves, sanitized diagnostics and priority support with signed tickets.
The dashboard can already pair phones securely, and revoking a phone ends its sessions. The iPhone app that uses it is being prepared.

Each device is read through a JSON driver. Search for your brand or filter by type and status.

Beta: the driver reads real data and is still being validated on more models.
Wi-Fi or LAN reading uses the inverter's logger (Solarman V5) or a Modbus TCP gateway.
The same local panel, packaged three ways. Pick the one that fits the hardware you already have.
What do you have?
Complete appliance for Raspberry Pi
Best for a dedicated installation: flash the image and finish setup from your phone.
Container for your server
For a mini-PC, NAS or server you already run. Same core, with data in a persistent volume.
App inside Home Assistant OS
If your home already runs on Home Assistant: HelioPulse lives in the sidebar and publishes sensors over MQTT.
Compared with a typical manufacturer cloud app.
| Aspect | HelioPulse | Typical cloud app |
|---|---|---|
| Data freshness | Live, straight from your local network | Depends on how often the device uploads to the server |
| Without Internet | Keeps recording and showing data | Usually stops showing data |
| Where your data lives | In your installation; you decide if anything leaves | On the provider's servers |
| Several brands | Inverters, BMS and chargers in one view | Usually one app per brand |
| If the service changes or shuts down | Your dashboard keeps working | You depend on the provider's decisions |
Want to check it away from home? Remote access is optional and uses an outbound tunnel, so there are no ports to open on your router.
Open beta: it runs every day in real installations, and some drivers are still being validated.
Today, yes. HelioPulse is in open beta and using it costs nothing. No decision has been made about charging for it in the future. If you want to help, you can support the project with a donation.
No. HelioPulse reads your devices and stores the data on your local network. Internet is only needed for what requires it: checking for updates, optional remote access, cloud backups, a cloud AI provider, or cloud integrations such as Kasa or Tuya.
Reading data changes nothing on the inverter. HelioPulse can also change settings on devices whose driver declares them, and that does carry risk if done without knowing what each setting does: a wrong value can affect battery charging or how the equipment operates. Those changes never happen on their own: you make them from the dashboard, you allow Home Assistant to make them with two permissions, or you enable an automation to write specific parameters of a specific device, with limits on how often it writes. HelioPulse reads the value back to confirm it and logs every change. If you are unsure about a setting, check the manufacturer's manual or ask your installer first.
The simplest option is a Raspberry Pi 4 (4 GB) or Pi 5 with HelioPulse OS. To connect the inverter, use a USB–RS485 adapter, the Wi-Fi logger many inverters already have, or an ESP32 collector. If you already run a server or Home Assistant, you can use Docker (amd64/arm64) or the Home Assistant app.
There are supported drivers for SRNE, Deye, JK BMS, Pylontech and Modbus EV chargers, and beta drivers for Growatt, Sungrow, Solis, GoodWe, Voltronic, INVT, EG4, MUST, Felicity Solar, Huawei and Victron. Look your device up in Compatibility; if it is missing, you can create a JSON driver or request it from the dashboard.
On HelioPulse OS, from the dashboard itself: it checks, downloads and installs signed OTA updates, and you can leave them on automatic. In Docker, pull the new image; in Home Assistant, update the app from Home Assistant.
In your installation: on the Raspberry Pi's SSD or microSD, or in the Docker volume. Device readings only leave your network if you turn on an integration, remote access, cloud backups, an AI provider in the cloud or an external MQTT broker you configure. This website's analytics are optional and unrelated to your dashboard.
It is optional and off by default. If you want it, connect Claude or OpenAI with your own key, or an Ollama on your network so nothing leaves your installation. Nothing is sent until an administrator turns it on and accepts the data notice. The assistant answers with your data and can propose changes, but you apply them yourself. Everything else in HelioPulse works the same without AI.
Yes, if you want to. Remote access is optional and uses an outbound tunnel from your device, so you don't have to open ports on your router. Without it, the dashboard works the same inside your network.
