This addon allows to use a device in order to input data to odoo automatically.
It opens a URL that a device can use to connect (with a password) that can only
execute an specific action.
Inputs are useful when a device wants to communicate to odoo for a single
and simple action.
This way, the device does not need to be configured with a odoo user and
password, it is handled by odoo devices.
There are two endpoints you can use:
Endpoint 1: /iot/<serial>/action
Takes application/x-www-form-urlencoded parameters:
passphase, value (where value is a JSON object)
- Create a Device on IoT > Config Devices
- Access the Inputs section of the device
- Create an input. You must define a serial, passphrase, function and model
The function that the system will call must be of the following kind:
@api.model
def call_function(self, key):
return {}
Where key is the input string send by the device and the result must be a dictionary
that will be responded to the device as a JSON.
Endpoint 2: /iot/<device_identification>/multi_input
It can be used to send values with multiple data in one POST request such as:
- Values for inputs of the same device with different address (multi input)
- Values for inputs of the same device with same address, different values (multi event)
- Mix of the above (multi input, multi event)
Takes application/x-www-form-urlencoded parameters:
passphase, values (a JSON array of JSON objects)
It is called using device_identification and passing two POST parameters: device passphrase and
a JSON string containing an array of values for input
- The value for the address key can be a string or a numeric (to conserve bytes in memory
restricted devices when creating the JSON object) and is converted to string when parsing.
- The value for the value key can either be string, number or boolean according to
JSON specs.
You can see an example of a valid JSON input object in the examples folder, using a few
combinations.
It requires the function that the system will call must be of the following kind:
@api.model
def call_function(self, key):
'do something
if err:
return {'status': 'error', 'message': 'The error message you want to send to the device'}
return {'status': 'ok', 'message': 'Optional success message'}
Where key is a dict send by the device having at least value for keys: ‘address’, ‘value’
The function must always return a JSON with status and message. If value contains a value
with ‘uuid’ as key, it is returned along with the object for the IoT device to identify
success/failure per record.
It has full error reporting and the return value is a JSON array of dicts containing at
least status and message. Error message respose is at some points generic, though
extended logging is done in Odoo server logs.
