A no-std Rust implementation of the DSMR5 standard.
In the first instance using an FTDI -> USB module the smart meter emits its status every second. Later I will be using a custom ARM embedded bord to transmit the status over Zigbee.
Plug an FTDI cable into your P1 port. Your RX line will probably need to be inverted. Most off-the-shelf P1 FTDI's already have this preconfigured.
Then create your own little crate using something like the serial crate, and use the Reader class like so:
``` let mut port = serial::open(&path).unwrap(); let reader = dsmr5::Reader::new(port.bytes().map(|b| b.unwrap()));
for readout in reader {
let telegram = readout.to_telegram().unwrap();
let state = dsmr5::Result::
println!("{}", state.power_delivered.unwrap());
} ```
