There is work in progress with a GATT profile implementation that can send acceleration data as a notification. You’d need a device to connect to RuuviTag and register to incoming notifications. I’d estimate that the SW is ready to be tested in a month or 2.
It is possible to configure the accelerometer to send interrupts, however our driver does not support the configuration modes as of right now.Personally I’d recommend implementing a circular buffer and sending the buffer when interesting event is detected. For an example you can check out https://github.com/ojousima/ruuvitag_fw/blob/feature-webble/ruuvi_examples/web-bluetooth/application.c , line 36 has condition when to send an accelerometer sample and lines 42 and 44 actually send the data.
A quicker solution would be to setup a listener to a sensortag firmware as shown in Collecting RuuviTag measurements and displaying them with Grafana
