prometheus p1 exporter
The prometheus p1 exporter is a simple (by design and purpose) binary that can read data from a smart meter through a serial port and expose these metrics to be scraped by prometheus.
configuration
The only things that can be configured with an environment var is:
- SERIAL_DEVICE: the device that needs to be read (usually something like /dev/ttyUSB0)
limitations
Lines are processed as they come in, no checksums are handled.
For now, only below fields are exported:
- Actual electricity power delivered (+P) in 1 Watt resolution
- Actual electricity power received (-P) in 1 Watt resolution
- Meter Reading electricity delivered to client (Tariff 1) in 0,001 kWh
- Meter Reading electricity delivered to client (Tariff 2) in 0,001 kWh
- Meter Reading electricity delivered by client (Tariff 1) in 0,001 kWh
- Meter Reading electricity delivered by client (Tariff 2) in 0,001 kWh
- Gas meter reading in m3
- Instantaneous voltage L1 in V resolution
- Instantaneous voltage L2 in V resolution
- Instantaneous voltage L3 in V resolution
- Instantaneous active power L1 (+P)in W resolution
- Instantaneous active power L2 (+P)in W resolution
- Instantaneous active power L3 (+P)in W resolution
- Instantaneous active power L1 (-P)in W resolution
- Instantaneous active power L2 (-P)in W resolution
- Instantaneous active power L3 (-P)in W resolution
For the OID's of these values, please refer to the ESMR 5.0 document.
