Everything you need to keep your DCM-1 running: LED reference, reset button, WiFi reset, FAQ, troubleshooting. If you can't find what you need, contact us.
The reset switch on the right side of the DCM-1 does two things.
Press EN once. The DCM-1 reboots, samples power / water / pads, and sends fresh status to your app within a few seconds. Use this any time you want the app to update immediately instead of waiting for the next hourly check-in.
If you moved the DCM-1 to a new WiFi network, changed your router password, or the DCM-1 stopped connecting to WiFi:
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. Then follow steps 4-6 above.
The DCM-1 has two LEDs on the right side: red (POWER) and green (STATUS). Both are event-driven in normal operation — the LEDs are off during deep sleep, so a DCM-1 that "looks off" is usually just sleeping between checks.
| Pattern | What it means |
|---|---|
| Red slow pulse (continuous, 2 s on / 2 s off) | Waiting for WiFi setup. Join DCM-1-XXXX on your phone. |
| Green fast blink (continuous, 5 Hz) | Connecting to your home WiFi. |
| 1 quick green | WiFi connected — all OK. |
| 5 quick green | WiFi connection failed. Device will retry on next wake. |
| 2 quick red | WiFi is fine but PianoCloud server unreachable. Will retry on next wake. |
| Pattern | What it means |
|---|---|
| Fast green blink for 10 s after boot | Reset window is open. Press EN now to clear WiFi credentials. |
| 5 quick red | WiFi credentials just cleared. Setup mode next boot. |
| 8 quick green | Automatic recovery — WiFi cleared after 24 hours offline. |
| Pattern | What it means |
|---|---|
| 2 quick green | Firmware update command received. Download starts shortly. |
| Red ↔ green alternating (~1 Hz) | Firmware downloading. Do not power off. |
| 5 quick green (after alternating pattern ends) | Update complete. Device rebooting with new firmware. |
| Pattern | What it means |
|---|---|
| 10 fast red flashes | Battery critically low. Replace the 3× AA lithium batteries now. |
When the DCM-1 first powers on (after a battery swap or manual reboot), it flashes its firmware version:
This only fires on fresh power-on, not on wake from sleep.
The DCM-1 is designed to run about one year on a fresh set of batteries.
Use 3× AA 1.5V Lithium only (Energizer Ultimate Lithium L91 recommended). Do not use alkaline or rechargeable batteries — they will not provide reliable operation across the DCM-1's temperature range and voltage requirements.
When battery voltage drops below a safe operating floor, the DCM-1 extends its sleep interval to conserve power. Your account (and any watcher techs you've invited) will be notified that the batteries need replacement.
No. The DCM-1 is a monitor only. It reads the status of your Piano Life Saver system but does not control, modify, or interfere with it in any way.
No. The DCM-1 runs on its own batteries. It sits between your PLS humidistat and the LED panel, but draws no power from either.
No. The DCM-1 uses patent-pending technology that preserves your Piano Life Saver system's warranty. Your H-5 humidistat plugs into the DCM-1, and the DCM-1 plugs into your LED panel — nothing is modified, cut, or spliced.
The DCM-1 keeps monitoring and reconnects automatically when WiFi is restored. You may see a gap in status updates during the outage, but no data is lost — the device reports its current status as soon as it reconnects.
The DCM-1 stops sending updates. Your Piano Life Saver system continues to operate normally — the DCM-1 is independent of the PLS. Replace the batteries and monitoring resumes.
Only if you have invited your technician as a watcher on your device. Your technician sees the same live status and alerts you do. Watchers can be invited or removed anytime from the app.
Approximately once per hour. If a fault is detected, you're notified within the hour.
Yes. Simply unplug the cables, install on the new piano's Piano Life Saver system, and (if the piano is in a different location) reset WiFi to connect to the new network.
The DCM-1 is compatible with Piano Life Saver systems that use the standard H-5 humidistat with the LED indicator panel.
Yes. Your device data is encrypted in transit and stored securely. Only you and the watchers you authorize can see your device status. PianoCloud does not sell or share your data.
| Symptom | Try |
|---|---|
| No status updates in app | Press EN once to force a fresh check-in. If that doesn't help, check that your router is on. |
| App shows device offline for hours | Battery may be low. Check the DCM-1: 10 fast red flashes confirms low battery. Replace with 3× AA lithium. |
| Power alert | Check that your Piano Life Saver is plugged in and its own power indicator is lit. |
| Water alert | Refill the Piano Life Saver water reservoir. |
| Pads alert | Contact your piano technician for pad replacement. |
| Can't connect to WiFi (green fast blink, then 5 quick green fail) | Password may be wrong. Reset WiFi (see above) and re-enter credentials. |
| Can't connect to WiFi (never connects) | Your router may be 5 GHz only. DCM-1 requires 2.4 GHz. Enable 2.4 GHz on your router or use a router that offers both. |
| DCM-1 not responding to EN press | Check the batteries. If they're fresh and the device is unresponsive, contact support. |
Firmware updates are delivered over-the-air automatically — no action required. When an update is pushed to your device, you'll see the sequence: 2 quick green (received), red ↔ green alternating (~30-60 seconds while downloading), 5 quick green (update applied), then the new firmware's boot version indicator.
Updates are only applied when battery voltage is high enough to complete the flash safely. If your batteries are low, the DCM-1 defers the update and will apply it after you replace the batteries.
