Thanks for sharing!

We have analysed similar pattern in many IoT devices and presented periodicity in IoT traffic as FFT (fig 4 - of IoTDI paper attached for reference) and some initial results here in this report:

Dear colleagues,

IoT devices often perform activities on a periodic basis. Thymen Wabeke
of SIDN Labs shares his analysis of periodic network traffic from IoT
lightbulbs. Read it on RIPE Labs at:

Kind regards,
