WCH SD31(2W Solar) - Node Details

This radio now reports as !4d1eaa8a WCH SD31(2W Solar). Firmware 2.8 derives the node number from the node's public key, so since the upgrade (new id first seen 2026-09-16) its packets, position and telemetry are recorded under the new id. This page no longer updates and the map hides its old marker. (linked by public key)
