That looks like a small appliance turning on and off fairly regularly, it's only small maybe 150W - do you have an aquarium ?
I'd say fridge/freezer or aquarium heater also

I do have an aquarium and maybe since it's getting generally cooler then heater might be cycling but it was still doing it during our last warm spell. As you can see from the 2 new screenshots, one for today and the other shortly after my installation, it didn't used to happen which is why it had me thinking. As long as it's nothing which points to an iffy installation or hardware/BMS issue I won't fret too much
I would turn on a high load like an oven and test that the load sensing via the ct is correctly working.

Just FYI i’ve also got an aquarium (with 2 heaters), the smaller one (200W) maintains the temperature and the bigger one (400W) does the leg work in winter.
This is my trace taken with home assistant which shows the regular heartbeat from the heater, on the warmer days of summer it obviously doesn’t cut in as much.
