WiFi-Connected Monitor for Piano Life Saver Systems
The PianoCloud DCM-1 is a small, battery-powered device that monitors the status of your Piano Life Saver (PLS) humidity control system and sends alerts to your phone. It checks for three conditions:
When a problem is detected, you receive a notification on your phone through the PianoCloud Monitor app. You can also invite your piano technician as a watcher on your device so they can see the same alerts and check status remotely — through the same PianoCloud Monitor app.
Your piano technician will install the DCM-1 during a service visit. The installation takes approximately 10 minutes and requires no modification to your Piano Life Saver system.
Important: The DCM-1 does not modify or interfere with your Piano Life Saver system in any way. It is a passive monitor only.
Tip: If you already have an account from a previous PianoCloud product, use the outlined Sign In button instead of Create Account.
| Indicator | Green | Red |
|---|---|---|
| Power | PLS system is powered on | PLS system has lost power — check that it's plugged in |
| Water | Water level is OK | Water reservoir needs refilling |
| Pads | Pads are OK | Pads need replacement — contact your technician |
The DCM-1 has two LEDs on the right side: Red (POWER) and Green (STATUS). Both are event-driven — the LEDs are off during deep sleep, so a DCM-1 that "looks off" is usually just sleeping between checks.
| Pattern | What it means |
|---|---|
| Green fast blink | Connecting to your home WiFi |
| 1 quick green | WiFi connected — all OK |
| 5 quick green | WiFi failed — will retry next wake |
| 2 quick red | Server unreachable — will retry next wake |
| Red slow pulse (continuous) | Waiting for WiFi setup — join DCM-1-XXXX |
| Fast green blink after boot (10 s) | WiFi-reset window open — press EN now to clear WiFi |
| 5 quick red | WiFi credentials cleared |
| Red ↔ green alternating (~1 Hz) | Firmware downloading — do not power off |
| 10 fast red flashes | Battery critically low — replace 3× AA lithium now |
Boot version indicator: on first power-on (battery swap or manual reboot), the DCM-1 flashes its firmware version: MAJOR slow red flashes, pause, MINOR slow green flashes, pause. Example: v1.1.0 = 1 slow red, pause, 1 slow green.
Full LED reference, including OTA update sequence and auto-recovery patterns, is on the DCM-1 Support page.
The DCM-1 connects to your home WiFi network to send status updates. It checks in approximately once per hour.
Your technician handles WiFi setup during installation. If you need to change the WiFi network (for example, after changing your router or WiFi password):
If you miss the 10-second window, no harm done — just press EN once to reboot and try again.
Automatic recovery: if the DCM-1 goes 24 hours without any successful WiFi connection (or 1,000 consecutive failed attempts), it clears its own WiFi credentials automatically and returns to setup mode. You'll see eight quick green flashes before it reboots.
The DCM-1 is designed to operate for approximately one year on a single set of batteries.
3x AA Energizer Ultimate Lithium (L91) — these are specifically recommended for their long shelf life and consistent voltage. Do not use rechargeable batteries or standard alkaline batteries.
When the battery voltage drops below a safe level, the DCM-1 will enter an extended sleep mode to conserve remaining power. Your technician will be notified that the battery needs replacement.
In the PianoCloud Monitor app:
No. The DCM-1 is a monitor only. It reads the status of your PLS system but does not control, modify, or interfere with it in any way.
No. The DCM-1 runs on its own batteries and does not draw power from your PLS system.
The DCM-1 will continue monitoring and will reconnect automatically when WiFi is restored. You may see a gap in status updates during the outage, but no data is lost — the device will report its current status as soon as it reconnects.
The DCM-1 will stop sending updates. Your Piano Life Saver system continues to operate normally — the DCM-1 is independent of the PLS. Replace the batteries and the DCM-1 will resume monitoring.
Only if you have invited your technician as a watcher on your device. Your technician uses the same PianoCloud Monitor app and can only see the devices you have authorized.
Approximately once per hour. If a fault is detected, you will be notified within one hour.
Yes. Your technician can reinstall the DCM-1 on a different Piano Life Saver system. The WiFi may need to be reconfigured if the piano is in a different location.
The DCM-1 is compatible with Piano Life Saver systems that use the standard H-5 humidistat with LED indicator panel.
Yes. Your device data is encrypted in transit and stored securely. Only you and your authorized technician can see your device status. PianoCloud does not sell or share your data.
