Sensor bulk data transfer


I have sensor that collect data every minute and send data to my own system every hour. Now I wish to switch to HA. Is it possible to somehow send data in bulk? I find the 5 year old post with same problem but without answer. So I ask again.


Home Assistant still requires data to be sent in real time.

I see tons of wishes similar to me and long ago. I don’t understand why this is so hard to do. If I can’t find a workaround then HA is unusable for me. (but as I see is in general far better than my pile of crap)
Need to investigate little more if using websocket bulk data can be used.
