How do I read a BME280 temperature/humidity sensor on a Pico?

import { defineConfig } from "@devicesdk/cli";

export default defineConfig({
  projectId: "bme280-monitor",
  devices: {
    sensor: {
      className: "EnvSensor",
      main: "./src/devices/envSensor.ts",
      deviceType: "pico-w",
      wifi: { ssid: "YOUR_WIFI_SSID", password: "YOUR_WIFI_PASSWORD" },
    },
  },
});

import { DeviceEntrypoint, type DeviceResponse } from "@devicesdk/core";
import { Pico } from "@devicesdk/core/devices/pico";

const I2C_BUS = 0;
const BME280_ADDR = "0x76";

export class EnvSensor extends DeviceEntrypoint {
  crons = { sample: "*/1 * * * *" }; // every minute UTC

  async onDeviceConnect() {
    // Configure the I2C bus once.
    await this.env.DEVICE.sendCommand(
      Pico.i2c({ bus: I2C_BUS, sda_pin: 0, scl_pin: 1 }),
    );

    // Verify the sensor is alive: read the chip-ID register (0xD0) — should be 0x60.
    const reply = await this.env.DEVICE.i2cRead(I2C_BUS, BME280_ADDR, 1, "0xD0");
    if (reply.type !== "i2c_read_result" || reply.payload.data[0] !== "0x60") {
      console.error(
        `BME280 not detected at ${BME280_ADDR}. Check wiring (SDA=GP0, SCL=GP1) and pull-ups.`,
      );
      return;
    }

    // Force-mode, x1 oversampling — see datasheet §3.4.
    await this.env.DEVICE.i2cBatchWrite ??
      undefined; // older runtimes used i2cBatchWrite; fall back to two writes.
    await this.env.DEVICE.i2cWrite(I2C_BUS, BME280_ADDR, ["0xF2", "0x01"]); // ctrl_hum
    await this.env.DEVICE.i2cWrite(I2C_BUS, BME280_ADDR, ["0xF4", "0x25"]); // ctrl_meas
    console.log("BME280 ready");
  }

  async onCron() {
    // Trigger a forced measurement (one-shot).
    await this.env.DEVICE.i2cWrite(I2C_BUS, BME280_ADDR, ["0xF4", "0x25"]);

    // Wait briefly for the conversion (datasheet table 9 worst-case ~10 ms).
    await new Promise((r) => setTimeout(r, 20));

    // Read 8 bytes starting at 0xF7: pressure (3), temp (3), humidity (2).
    const reply = await this.env.DEVICE.i2cRead(I2C_BUS, BME280_ADDR, 8, "0xF7");
    if (reply.type !== "i2c_read_result") return;

    // Parsing the calibration data and applying the BME280 compensation
    // formulas is omitted here — see the project repo for a full driver.
    // For demo purposes: log the raw bytes.
    console.log("BME280 raw:", reply.payload.data.join(" "));
  }

  // Surface command errors so we know if the sensor wandered off.
  async onMessage(message: DeviceResponse) {
    if (message.type === "command_error") {
      console.error(`I2C error: ${message.payload.error}`);
    }
  }
