Write efficient code, save money
Better code means lower costs. Here's how to optimize.
Use time-based monitoring wisely
Check values at appropriate intervals instead of constantly polling.
// Check temperature every 5 minutes instead of every second
await this.env.DEVICE.configureAdcMonitoring(26, {
interval: 300000 // 5 minutes = ~288 messages/day
});Use event-based monitoring
Only send messages when values actually change.
// Only notify when GPIO state changes
await this.env.DEVICE.configureGpioInputMonitoring(20, true);
// Messages only sent on actual button pressesUse smart thresholds
Only alert when values cross important thresholds.
// Only send alert when temperature is out of range
if (temp > 30 || temp < 10) {
await this.sendAlert(temp); // Only when necessary
