To check if the node is available in the network, a HTTP GET to /shelly is issued. This route returns a type string which is verified. You can configure an interval for the polling. The default is 5000ms, 0 is off = no polling. Most nodes will call HTTP GET to the /status route after a input is received from the node. This answer is directly available at the output via msg.status. The msg.payload property contains a lightweight version of this status object. The hostname can be left empty in the configuration node. This deactivates polling, too. In this case you must pass the hostname in the msg.payload.hostname. This can be useful, if you want to use one node for several devices or if you want to make use of sub flows. (username and password can be passed in msg.payload, too)
{
hostname : '192.168.178.250'
username : 'user'
password : 'password'
...
}
Unlike generation 2 devices which support scripts the older generation 1 supports only webhooks which are very limited. You can always use polling mode, but some devices like sensors and buttons often sleep to safe energy. In this state the node can not reach the shelly in the local network. This results in a polling error which is not a problem, but often generates confusion when the user sees error messages in the node-red debugger or console. To avoid this you can try to enable callback mode. In callback mode a webhook is configured to the shelly which notifies to the node when sensor data changed. The node needs to open a network port to be able to receive these messages. You must configure this network port, make sure that it is not already in use. If node-red runs inside a docker container or any other bridged network then you should also configure the hostname under that the shelly device can reach the node-red server (Leave this field empty if you run inside the same network segment). The node retries to set the webhook if the device is sleeping as long as it succeeds. As soon as the status shows "Connected" the webhook is set.
See also https://shelly-api-docs.shelly.cloud/gen1/#shelly-family-overview The node can communicate with several shelly types. You must select the correct device type from the combobox when configuring the node. Devices are grouped as follows:
You can configure your shelly from within the web interface. But there is also the possibility to change the settings from with a flow. Simply pass one or more settings objects in msg.settings:
[
{
device : 'ext_temperature',
index : 0,
attribute : 'overtemp_threshold_tC',
value : 90
},
{
device : 'ext_temperature',
index : 0,
attribute : 'overtemp_act',
value : 'relay_on'
}
...
]
To understand the properties please have a look at: https://shelly-api-docs.shelly.cloud/gen1/#shelly1-1pm-settings-ext_temperature-index It always follows the same scheme "/settings//?="
The node is able to turn on and turn off a shelly switch. It outputs the status of all relays after every interaction with the shelly device. Turning on is done by sending the following payload into the input. The relay number is optional and defaults to 0. Note that the UNI can also deliver the ADCS values in the status.
{
relay : 0,
timer : 1,
on : true
}
or you can make use of the alternative notation:
{
relay : 0,
timer : 1,
turn : 'toggle'
}
turn can be one of the following: 'toggle', 'on', 'off' timer is optional flip back timer in seconds
Right after having sent the request to the shelly device a status request is done. The relays property of the response is output on output 1.
If you only want to get the current status of the switch without turning on or off you should leave the msg.payload blank. This is useful, when you want to poll for the status cyclically.
The output of the node is an array of status objects for every relay of the switch:
relays : [
{
ison : true,
...
},
{
ison : true,
...
},
],
meters : [
],
inputs : [

[
{
download : [0, 1, 2],
...
},
]
The download variable contains a list of channels that should be downloaded. This can be either one or more numbers. Note that downloading from the device can take some seconds as it depends on the size of the gathered data. Data is sent to output 2.

temp : 2700, // for bulb duo (same as white but in K 2700 - 6500)
transition : 0 // for bulb duo (0..5000ms)
}
Like in the switch node you can replace on with turn and choose a value from the following: 'toggle', 'on', 'off'
You can also control the shelly state and brightness independently.
{
on: true
}
and
{
brightness: 100
}

The node is able to poll a shelly window/door, motion, gas, ... sensor. It outputs the sensor status together with battery and sensor values on every change sensor status. Note that some sensors sleep when nothing is detected and is thus not accessible via REST.
The output of the window, door sensor is as follows:
{
sensor
{
state: 'close',
is_valid: true
},
lux
{
value: 150,
illumination: 'twilight',
is_valid: true

{
input : 0,
event : 'S'
}
Event can be one of the following S=short push, SS=double short push, SSS=triple short push, L=long push (and LS=long short and SL=short long for the I3). Right after having sent the request to the shelly device a status request is done. The inputs property of the response is output on output 1.
If you only want to get the current status of the switch without turning on or off you should leave the msg.payload blank. This is useful, when you want to poll for the status cyclically.
The output of the node is an array of status objects for every relay of the switch:
[
]
Note that the button is not always reachable as it falls to sleep. This is not the case for the I3.
See also https://shelly-api-docs.shelly.cloud/gen2/ See also https://shelly-api-docs.shelly.cloud/gen2/Devices/ShellyPlus1PM The node can communicate with several shelly types. You must select the correct device type from the combobox when configuring the node.
Unlike generation 1 devices the new generation supports the usage of scripts. In polling mode the node just behaves like the generation 1 node. In callback mode a script is uploaded to the shelly which sends all notification events to the node. The node needs to open a network port to be able to receive these messages. You must configure this network port, make sure that it is not already in use. If node-red runs inside a docker container or any other bridged network then you should also configure the hostname under that the shelly device can reach the node-red server (Leave this field empty if you run inside the same network segment).
The node is able to turn on and turn off a shelly switch. It outputs the status after every interaction with the shelly device. Turning on is done by sending the following payload into the input. The relay number is optional and defaults to 0.
{
method : 'Switch.Set'
parameters : {
id : 0,
on : true,
toggle_after : 2 // optional flip back time in seconds
}
}
or you can make use of the alternative toggle command:
{
method : 'Switch.Toggle'
...
}
Note that toggle_after is optional. The unit is seconds. Right after having sent the request to the shelly device a status request is done.
If you only want to get the current status of the switch without turning on or off you should leave the msg.payload blank. This is useful, when you want to poll for the status cyclically.
The output of the node is the full status object of the device. See https://shelly-api-docs.shelly.cloud/gen2/Overview/CommonServices/Shelly
For further rpc commands see the shelly documentation.
The node is able to control a shelly button. It outputs the status of all inputs after every interaction with the shelly device. See https://shelly-api-docs.shelly.cloud/gen2/Components/FunctionalComponents/Input
The output of the node is an array of status objects for every relay of the switch:

The node is able to control a shelly sensor. Usually sensors sleep all the time to save energy. Hence you will get an error when polling for the status but sometimes when the device wakes up you will receive valid data. Another possibility is to use the callback mode. Unlike other 2. generation devices sensors do often not support scripts. Therefore webhooks are installed as soon as the device is not sleeping. When the shelly calls the webhook, the node gets the status and sends it to the output. You can wake up your device manually on redeploy to speed up initialization. Otherwise errors will be generated in the debugging pane telling you that installation of the webhook failed.
For a complete documentation see also https://shelly-api-docs.shelly.cloud/#common-http-api
See also https://shelly-api-docs.shelly.cloud/cloud-control-api/communication The node can communicate with your shellies via cloud API. You need to create an authentication key in your shelly app and enter it into the config node. All devices have unique IDs. You can configure the ID in the config node or send it into the node, just as you prefer. Note that the cloud API is limited to 1 call per second. If you call too fast you will likely receive an error 401. You can get the status of a device by simply triggering the node using a msg.payload as follows contains the id of the device
{
type : 'status',
id : 'your device id here in hex',
}
You can control relays as follows:
{
type : 'relay',
id : 'your device id here in hex',
channel : 0,
turn : on | off
}
You can control rollers as follows:
{
type : 'roller',
id : 'your device id here in hex',
direction : open | close | stop
pos : 0..100
}
Please use direction or pos here.
You can control lights as follows:
{
type : 'light',
id : 'your device id here in hex',
channel : 0,
turn : on | off
white : 0..255
red : 0..255
green : 0..255
blue : 0..255
gain : 0..255
brightness : 0..255
}
Please see documentation. It depends on if you have RGBW or White lights.
You can turn on|off many relays or rollers with one single call as follows:
{
type : 'relays',
turn : on | off,
devices : [
{
id : 'your device id here in hex'
channel : 0
},
{
...
}
]
}
