“P1 Bluetooth monitor” application allows for reading data from the P1 port of the smart meter. It works with the following Bluetooth devices (produced by tech4u.nl): BP1-605-L, P1M-009, P1M-010, BPL-007-P and P1S-003-L. These devices are intended for installers who install or service Smart Meters (SM). The devices can be used for testing the functionality of SMs and to read SM data via the P1 port. The read data and test results are then transmitted via Bluetooth to the "P1 Bluetooth monitor"
