Strato
Strato Pi is an expansion board developed by Sfera Labs for the Raspberry Pi computer.
Strato Pi implements a number of hardware features to expand the Pi and allows its use in professional applications:
- 9-28 Vdc extended-range power supply
- integrated UPS with external NiCd rechargeable battery
- real-time clock with dedicated back-up battery
- opto-isolated RS-232 or RS-485 serial port
- configurable hardware watchdog
- buzzer for audible feedback.

HSYCO Configuration
Add a STRATO I/O Server in the I/O Servers section of the Settings and set its parameters.
Note that the Strato I/O Server doesn't count in the I/O servers license total, so you don't need an extra I/O Server license to use Strato with HSYCO.
High Availability
- Shutdown when inactive: defaults to false.
Options
| ID | Default | Values | Description |
|---|---|---|---|
| watchdog | false | true | enables the hardware watchdog and automatically generates the heartbeat signal (Strato Pi Mini board not supported) |
| false | disables the hardware watchdog | ||
| shutdown_minutes | 0 | 0 | no automatic shutdown after power failure |
| int > 0 | the driver will command the operating system shutdown and hardware power off after N minutes of back-up battery operations during a power failure. The Strato board will automatically power-up the Pi when power is restored (use this option only with the Strato UPS board) | ||
| quiet | false | true | enables audible alarms on power failure |
| false | disables audible alarms on power failure | ||
| version | base | base | Strato Pi Base and UPS boards |
| mini | Strato Pi Mini board | ||
| cm | Strato Pi Compute Module |
Datapoints
| ID | Value | R/W | Description |
|---|---|---|---|
| backlight.brightness | <brightness> | R | the current backlight brightness of HSYCO Pi Touch Display |
| W | set brightness of HSYCO Pi Touch Display to a value between 0 (off) and 255 (max) | ||
| battery (base/ups only) |
0 | R | power supply is available |
| 1 | R | power supply failure, running on UPS battery | |
| beep (base/ups/mini only) |
0 | R | buzzer is off |
| 1 | R | buzzer is on | |
| off | W | turn buzzer off | |
| on | W | turn buzzer on (continuous tone) | |
| <duration> | W | turn buzzer on for <duration> seconds (decimals allowed) | |
| <duration>;<pause> | W | turn buzzer on for <duration> seconds, then pause for <pause> seconds (decimals allowed) | |
| cpu.temperature | <temperature> | R | the current CPU core temperature in Celsius degrees |
| led (cm only) |
0 | R | led is off |
| 1 | R | led is on | |
| off | W | turn led off | |
| on | W | turn led on | |
| <duration> | W | turn led on for <duration> seconds (decimals allowed) | |
| <duration>;<pause> | W | turn led on for <duration> seconds, then pause for <pause> seconds (decimals allowed) | |
| heartbeat (base/ups/cm only) |
0 | R | heartbeat line is off |
| W | set heartbeat line to off | ||
| 1 | R | heartbeat line is on | |
| W | set heartbeat line to on | ||
| shutdown (base/ups/cm only) |
0 | R | shutdown line is off |
| 1 | R | shutdown line is on | |
| W | set shutdown line to on (Strato will wait approximately 60 seconds, then execute a power off-on cycle). Once the shutdown line is set to on, the power cycle procedure can't be reset. On Strato Pi CM, a hardware reset of the Compute Module is performed, while the power is not removed | ||
| timeout (base/ups/cm only) |
0 | R | hardware watchdog timeout line is off |
| 1 | R | hardware watchdog timeout line is on. Strato will set this line to on, then wait approximately 60 seconds and execute a power off-on cycle. On Strato Pi CM, a hardware reset of the Compute Module is performed, while the power is not removed | |
| watchdog (base/ups/cm only) |
0 | R | hardware watchdog is disabled |
| W | disables the hardware watchdog | ||
| 1 | R | hardware watchdog is enabled | |
| W | enables the hardware watchdog. When enabled, Strato should see an off-on transition on the hearbeat line at least every 60 seconds, otherwise a power cycle will be initiated, setting the timeout line on, then waiting 60 seconds, removing power to the Pi for 5 seconds, and finally restoring power. On Strato Pi CM, a hardware reset of the Compute Module is performed, while the power is not removed |
