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. Your piano technician can also monitor your system remotely through the PianoCloud Tech Tools 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 |
| LED | Behavior | Meaning |
|---|---|---|
| Red (Power) | Steady on | DCM-1 has battery power |
| Yellow/Green (Status) | Brief blink | Device is checking in — normal operation |
| Yellow/Green (Status) | Rapid blinking | Device is starting up or connecting to WiFi |
| Yellow/Green (Status) | No blink | Device is in deep sleep — conserving battery (normal) |
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):
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 to monitor your device. Your technician uses the PianoCloud Tech Tools 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.
