IonoPi

Iono is a general-purpose, professional input/output module based on a standard Arduino microcontroller.

iono Pi

This driver provides support for iono Ethernet employing the HTTP API provided by the IonoWeb library.

The default sketch installed in iono Ethernet exposes this API.

HSYCO Configuration

Add a IONO I/O Server in the I/O Servers section of the Settings and set its parameters:

Communication

• IP Address: the IP address assigned to iono;

High Availability

• Shutdown when inactive: defaults to true.

Options

ID	Default	Values	Description
startupevents	true	true	generate IO events also during the driver’s start-up phase
		false	start generating events only after HSYCO is aligned with the current status of the system
pollinterval	0	0	the driver will use the push notifications sent by iono to monitor its changes
		int > 0	the driver will poll iono's state with the specified time interval (in seconds). Push notifications won't be enabled
input1	digital	digital	the specified multi-mode input will be read as digital signal (DI<n>)
input2
input3		voltage	the specified multi-mode input will be read as analog voltage (AV<n>)
input4		current	the specified multi-mode input will be read as analog current (AI<n>)
stabletime	100	int > 0	number of milliseconds an input must be stable before a push notification is sent by iono to HSYCO
minvariation	0.1	float > 0	minimun value variation (for analog inputs) to trigger a push notification
subscribehost		<host_name>	hostname or IP address to be used by iono to send push notifications. Leave blank to let the driver discover the local address

Datapoints

For inputs 1 to 4, depending on the 'input1' ... 'input4' options, only the corresponding datapoint will be created, i.e. di<n> (if digital), av<n> (if voltage) or ai<n> (if curent).

ID	Value	R/W	Description
connection	online	R	connection established
	offline	R	HSYCO can't connect to the device
do<n>	0	R	relay <n> (digital output) is off
		W	switch off relay <n>
	1	R	relay <n> (digital output) is on
		W	switch on relay <n>
di<n>	0	R	digital input <n> is low
	1	R	digital input <n> is high
av<n>	<val>	R	analog input <n> is reading a voltage equal to <val> (in Volts)
ai<n>	<val>	R	analog input <n> is reading a current equal to <val> (in mA)
ao1	<val>	W	set the analog output to <val> Volts

User Interface

To control a digital output (DO1 ... DO6), add a button or a buttonicon object to your project page and set its address field to the corresponding datapoint:
