sainsmart contains code for working with sainsmart products.

pip install sainsmart

To use EthernetRelay in a project:

from sainsmart import devices

relay = devices.EthernetRelay()

# Access the state of the relays
# relay.state() is a list of bools
relay_state = relay.state()

# Turn on the relay at index 0.
relay.turn_on(0)

# Turn off the relay at index 0.
relay.turn_off(0)

# Toggle the state of relay 0.
relay.toggle(0)

# Turn on all relays.
relay.all_on()

# Turn off all relays.
relay.all_off()

The SainSmart Ethernet Relay defaults ip address: 192.168.1.4/30000. This can be changed through their web interface.

To use EthernetRelay with a different IP address:

from sainsmart import devices

relay = devices.EthernetRelay('https://192.168.44.100/30000')

Here is an example with a real device:

>>> from sainsmart import devices
>>> relay = devices.EthernetRelay()
>>> relay.state()
[False, False, False, False, False, False, False, False, False, False, False, False, False, False, False, False]
>>> relay.turn_on(0)
>>> relay.state()
[True, False, False, False, False, False, False, False, False, False, False, False, False, False, False, False]
>>> relay.toggle(0)
>>> relay.state()
[False, False, False, False, False, False, False, False, False, False, False, False, False, False, False, False]
>>> relay.all_on()
>>> relay.state()
[True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True]
>>> relay.turn_off(0)
>>> relay.state()
[False, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True]
>>> relay.all_off()
>>> relay.state()
[False, False, False, False, False, False, False, False, False, False, False, False, False, False, False, False]
