EcoFlow Delta Pro Firmware Updates: HA Integration Risk

A notification badge on your EcoFlow Delta Pro unit in the app, and a simple question follows: update now or dismiss? For most owners the answer is straightforward — update and get whatever fixes and improvements EcoFlow has shipped. But if your Delta Pro is wired into a Home Assistant automation that schedules charging around smart meter tariffs or manages the unit as part of a wider energy system, a firmware update carries real risk that the notification does not mention. As one owner laid out the dilemma in June 2026: “I am just wondering if anyone has updated it and if this has caused any problems with the integration not working anymore” — a question that captures exactly the tradeoff a thoughtful owner faces. (hassio-ecoflow GitHub, June 2026)

This guide covers what EcoFlow firmware updates actually change, how the popular hassio-ecoflow Home Assistant integration can break when firmware shifts, and a safe-update process for owners who have invested time in automation setups they cannot afford to lose. It is written specifically for Delta Pro owners — the models (Delta Pro, Delta Pro 3) where integration with Home Assistant is most common due to their whole-home backup positioning.

How the hassio-ecoflow integration works

The hassio-ecoflow integration does not talk directly to your Delta Pro over your local network. Instead, it communicates with EcoFlow’s cloud MQTT broker — a message bus that relays data between your device and external services. Your Delta Pro pushes state data to this broker over its Wi-Fi connection, and the integration subscribes to the relevant topics to read battery state of charge, input and output watts, cell temperature, and other telemetry. Commands (set charge limit, trigger smart charging mode) go the other direction through the same broker.

The dependency on EcoFlow’s cloud infrastructure is what creates firmware-update risk. When EcoFlow ships a new firmware version, they sometimes simultaneously update the MQTT topic names, the payload format, or the authentication token structure. The integration on your Home Assistant instance is still subscribed to the old topic names and expecting the old payload shape. The device publishes data to the new topic; the integration receives nothing; your automations quietly stop working. The Delta Pro itself is fine, the EcoFlow app still works, and there is no error message that points to the root cause. This is the scenario that makes the update-or-wait decision non-trivial.

What firmware 1.0.1.61 specifically changes

EcoFlow’s firmware 1.0.1.61 for the Delta Pro is documented primarily through community testing rather than an official changelog — EcoFlow does not publish line-by-line firmware notes for portable power station models the way software companies publish release notes. The change that has driven most owner discussion is the fan speed curve adjustment: the update reduces the frequency and aggressiveness of the cooling fan under moderate thermal loads, which many owners found audible during overnight charging. Six months of community reports suggest this fix works as advertised and the fan is genuinely quieter at typical indoor temperatures.

The update also includes changes to battery management logic — adjustments to how the BMS handles charge termination and cell balancing. These kinds of changes are generally beneficial and are similar to what EcoFlow addressed in the more visible DELTA Max 2000 recall firmware fix, which we covered in our guide to checking your serial and applying that patch. The difference is that a BMS logic change, however minor, is exactly the kind of payload-level update that can change MQTT message structure as new data fields are added, old ones deprecated, or the state machine behind them modified.

The break scenario: what actually fails and why

When a firmware update changes the MQTT broker topic structure for a Delta Pro, the most common failure mode is silent data loss: the integration appears connected, Home Assistant shows the EcoFlow entity as online, but the sensor values freeze at their last-known state and never update. If your automation is triggered by the battery’s state of charge dropping below a threshold (start smart generator, shift to grid import, alert on low battery), a frozen value means the trigger never fires. Your unit drains past the threshold and nothing happens. For an owner who built automations specifically to prevent overnight drain-downs, this failure is the exact opposite of what the system was designed to do.

A subtler failure involves authentication token expiry. EcoFlow occasionally rotates its MQTT broker credentials in conjunction with firmware updates. If the integration’s stored token expires without being re-issued, the connection silently drops rather than throwing an obvious authentication error. Re-adding the EcoFlow account in the hassio-ecoflow configuration forces a new token fetch and fixes this variant without requiring any integration code update. This is always worth trying first when the integration stops updating after a firmware push.

Safe-update checklist for owners with active automations

Before accepting a firmware update on a Delta Pro that is integrated with Home Assistant: first, check the hassio-ecoflow GitHub issuesfor any thread mentioning the specific firmware version. Search for the version number (e.g. “1.0.1.61”) and read through any open threads. If multiple owners have already updated and reported continued integration functionality, you can proceed with more confidence. If the thread is open with no confirmed positive reports, treat the update as unverified.

Second, take a screenshot or export your current automation configurations before updating. Home Assistant’s automation editor lets you view the YAML for each automation — copy it to a text file. If the update breaks something, you will need these configurations to rebuild rather than reconstruct from memory. Third, update the integration to the latest version in HACS before updating the device firmware, not after. Integration maintainers often push compatibility patches ahead of anticipated firmware releases, and running the newest integration version gives you the best chance of surviving a protocol change. Fourth, update the device firmware and immediately test each integration entity — confirm battery percentage is updating, confirm watts in and out are live, and trigger a manual automation to verify the command path is still working. This verification should happen within the first 30 minutes after the firmware applies while you are present to diagnose issues.

If the update has already broken your integration

If you are reading this after the fact — the firmware update went through and your automations have stopped working — the diagnostic sequence is: try re-authentication first (remove and re-add the EcoFlow account in the hassio-ecoflow configuration). This resolves credential-rotation issues and takes about two minutes. If that does not restore live data, check the integration’s logs in Home Assistant under Settings > Devices & Services > hassio-ecoflow > Logs. Connection refused, topic subscription errors, or JSON parse failures all point to specific failure modes with specific fixes.

If re-authentication and the current integration version do not resolve the issue, the most reliable path is to open a GitHub issue on the hassio-ecoflow repository with your firmware version, integration version, and the specific log errors. The integration community has historically turned around compatibility fixes for Delta Pro firmware changes within a few days to a week. In the meantime, you can still manage the unit manually through the EcoFlow app — the app is unaffected by integration breakage — and resume automations once a compatibility-patched integration version ships. This is a case where keeping the EcoFlow app set up and familiar pays off even for owners who rely primarily on Home Assistant, which is exactly the kind of monitoring fallback we cover in our guide to the EcoFlow app dashboard.

The broader principle: hold back if you are dependent

The general rule for any connected appliance integrated into an automation system is to treat firmware updates as software releases that carry breaking-change risk, not as silent maintenance updates that are always safe to apply immediately. For an EcoFlow Delta Pro that is only used through the EcoFlow app, updating promptly is almost always the right call — EcoFlow ships legitimate improvements and security hardening through firmware, and the fan-noise fix in 1.0.1.61 is a real quality-of-life improvement. But for a unit that is running automations your household depends on — charge scheduling, load shedding, emergency alert thresholds — the two-minute check of the integration’s GitHub issues before updating is the kind of routine that prevents a broken smart-home system at 2 AM during an actual outage.

EcoFlow has generally been good about not changing MQTT structures without warning in the community, and most firmware updates have not broken integrations. But “usually fine” is not the same as “always fine,” and the cost of holding the update for a week while the community confirms compatibility is much lower than the cost of spending an evening debugging why your automation that was supposed to protect the battery stopped working. The note on the GitHub issue as of June 2026 remains unresolved — if you are on 1.0.1.18 and your system is working, a brief pause while others test 1.0.1.61 is entirely reasonable.
