Sense data buffer?

[andrewchong]

I’m going to take down my wifi to do some rewiring of some cables and rearrange my office. Probably going to take an hour at most.
How much of a data buffer does Sense have? Don’t want to lose data unless absolutely necessary.
I’ve noticed that my wifi has gone down for brief times but the data seems to retroactively repopulate.

I believe that the buffer period is 6 hours. You may also be able to bring it down for say four hours at a time, bring it up for an hour or two, then down again. This would help for longer outages.

Offline mode

Actually, 6 hours seems plenty reasonable to me…

I’ve had Sense retain up to 8 hours but have also had it lose data after just an hour. I don’t believe the 6 hours stated is absolute.

What happens if Sense loses Wi-Fi connection?

If Sense is unable to reconnect, the monitor can hold at least six hours of device-specific, per-second offline data. After that space is exhausted, the data may be lost, but the monitor will try to preserve per-minute data for whole home consumption and solar production for a minimum of three months. Note that in cases where multiple power outages occur while Sense is disconnected from Wi-Fi, further data loss can occur.

So, 6 hours for real-time data. However, if multiple power outage occur, you’ll lose that data as it is on volatile memory.

Thanks for the reply. My 1 hour project took almost 4 hours. No appreciable loss of data.

That’s how it always goes for me…
