Thanks for the report — I can take a look, but I’ll need logs to debug this. Please add:

The device doesn't seem to respond. Try restarting the device either via the App using BLE or by pressing the physical button for 10s. |

Issue Description
HMJ-2 stopped responding - App offline, no telemetry, no BLE response
Hello,
I'm experiencing a communication problem with my Marstek / HAME HMJ-2 and would appreciate any help.
Environment
Timeline
The system had been working correctly for several weeks.
After a Home Assistant OS update followed by a reboot (around 2026-07-04) the HMJ-2 became unreachable.
Since then:
hm2mqtt configuration
pollingInterval: 10
responseTimeout: 45
enableCellData: false
enableCalibrationData: false
enableExtraBatteryData: false
allowedConsecutiveTimeouts: 8
topicPrefix: hm2mqtt
mqttProxyEnabled: false
log_level: info
devices:
deviceId: 18cedf985a05
hm2mqtt log
hm2mqtt starts correctly and connects successfully to the MQTT broker.
Afterwards it continuously reports:
WARN: No response received from 18cedf985a05 within timeout period
No successful communication ever occurs.
MQTT
MQTT Discovery works correctly.
All Home Assistant discovery topics are published correctly.
However, the topic
hm2mqtt/HMJ-2/device/18cedf985a05/data
never publishes any payload.
Only availability topics are published.
Network
The HMJ-2 is still reachable on the local network.
Ping to 192.168.25.63 works reliably.
HTTP and HTTPS connections are refused (which I assume is expected because the device has no web interface).
Bluetooth
The device is visible during BLE scanning.
However:
Current behaviour
The inverter still produces PV power during daytime.
However:
What I already checked
Questions
Is this a known issue with firmware 116.6?
Can the HMJ-2 enter a state where:
Is there any recovery procedure besides physically power cycling the unit?
Could the communication stack (BLE / WiFi / local MQTT) become stuck after a reboot?
I can provide complete hm2mqtt logs, MQTT traces and Home Assistant diagnostics if needed.
Thank you very much.
