10E0: Device Information

Some devices will periodically send device information with solicitation:

059  I --- 34:064023 63:262142 --:------ 10E0 038 000001C8380A0100F1FF1C0307E1030B07DE5438375246323032350000000000000000000000

Some devices send it upon startup, whilst other Round thermostats appear to send this data once every 24 hours.

Some devices (Controller, Opentherm Bridge) will respond to an RQ with this data.
