Radshid sits on a high Traccar TCP port — 5265 — as a binary dialect (RadshidProtocolDecoder). There is no friendly ) or BSTPL$ marker to grep in a text editor; identification is port + binary accept logs + vendor sheet.
ThinkPower is not a shortcut
ThinkPower binary on 5228 is a different decoder. Copy-pasting ThinkPower firewall rules onto 5265 still leaves the wrong grammar if the device is Radshid.
