Here's a complete backend for a Power Distribution template:

const express = require('express');
const app = express();

let breakers = { Main:"OFF", AC:"OFF", Lights:"OFF" };

app.get('/api/powerdb/status', (req, res) => {
  res.json({
    voltage: 230, current: 12.5, power: 2.8,
    freq: 50.0, pf: 0.97, kwh: 1250,
    grid: true, status: "OK"
  });
});

app.post('/api/powerdb/breaker', (req, res) => {
  breakers[req.body.breaker] = req.body.state;
  console.log(`Breaker ${req.body.breaker} -> ${req.body.state}`);
  res.json({ ok: true, breakers });
});

app.listen(3000, () => 
  console.log("HAL PowerDB running on :3000")
);
