Hey guys,

i notice something with the schedule feature on the balcony system. The schedule is delayed by exact one hour. I assume that this issue have something to do with the change to summertime (+1 hour).

Is anyone experince the same with their units that have the feature?

@BLUETTI Can you report this issue to the relevant departement?

Thanks
Erik

18:45 - 23:59 use Battery. Clock shows 18:49. So it should use battery Power

@Selfmadestrom Sorry for late reply Erik.
The technical team replied: This is synchronized with the server time and is calculated based on the standard time of the selected time zone.

Okay, so “standard time” here is the winter time. Summertime is +1 hour. Seems like i need to configure my schedule 1 hour earlier to work with summertime. A bit weird. But if this isn’t a bug and intended as it is, good to know^^

Hi Erik,


The technical team has reconfirmed this with R&D:
It may be because the balcony solar system only has synchronized system time when it’s first bound to app, and then the time synchronized by the first binding will prevail. So once the time goes from Winter Time to Daylight Saving Time, the time will be one hour different.

@Selfmadestrom
At the same time, thank you very much for identifying this issue. The tech team has also suggested the R&D. It should be resolved through an APP upgrade in the future. The revised strategy is to synchronize the system time whenever the balcony system is connected to the app.

Hi @BLUETTI,
I just searched the forum because I have a similar problem with my EP600.
Does this also apply to other BLUETTI products, that they only synchronise the system time when it’s first bound to app, but not afterwards, never?
Can synchronisation be ‘forced’ in some way without having to disconnect the device from the app?
My EP600 is now several hours ‘behind’ (27h17min), which is noticeable when setting a schedule…

Hello, can you provide your sn code?

Of course, I can provide the SN.

Hello, please try configuring the Wi-Fi with the app once to see if it resolves the issue.

Hi @BLUETTI ,
ok thx, reconfiguring the WiFi with APP solved the date/time gap.
I record some values per bluetooth interface and see after reconfiguring the new and actual date/time. The remaining time difference of a few seconds results from the Bluetooth transmission to the MQTT host and the subsequent readout via the MQTT client.
