Esphome - buffer mode?

I was wondering if there is a way to make such that data measured by EspHome are not lost in case wifi connection is not available.

For some application it is not really needed, in fact, realtime logging but what you want is long time data stats: in that case, even if wifi connection drops, buffering and sending data when connection is available would work.

is it something possible with EspHome?

Already thought about it in past and it’s not possible due to some restrictions in HA that doesn’t allow to get past data unhappy :frowning:
