You can get the data as JSON.
All sensor data: http://<ip>/json?view=sensorupdate
Specific for a single task: http://<ip>/json?view=sensorupdate&tasknr=2 (tasknr 2)

Hi,
Thanks for the answer.
But it looks like we get the latest taskX record value, not the actual value.
Is there any command to trigger to read the value of the device?
As I do not speak very well english I'm not sure you'll understand me :-( . So, here is what I would like:
I've configured a task which work on a ADS1115 to measure a voltage. The voltage is measured every 300 seconds and sended to domoticz through an MQTT broker.
Sometime Domoticz need to have the actual value (not the latest measured), so it will be nice to send a request to the ESP to measure immediatly the device and send the value to the controller(s).
Is it possible ?
Thank you very much.

First run a "taskrun" command and you will have the latest value.

Hi,
1) Is there a way to obtain the same result for 1 task without json (simplier) ?
2) Where can I find a list of such commands like json, taskrun etc.
Thanks a lot

See here for a list of the commands: https://espeasy.readthedocs.io/en/lates ... mmand.html

What do you need to get, not in JSON format?
For example like this? (tasks and value numbers start counting at 0)

All values of a task: http://<ip>/csv?tasknr=1
A single value of a task: http://<ip>/csv?tasknr=1&valnr=0
A single value of a task without header: http://<ip>/csv?tasknr=1&valnr=0&header=0

For CSV like output it is possible to address per sensor value.
See: https://espeasy.readthedocs.io/en/lates ... =json#json

What ESPEasy version are you running?

Also keep in mind you need to count from 0.

So tasknr and valnr start counting at 0.

Please tell me how to convert data from

Code: Select all

/ json? View = sensorupdate & taskrun = 2
into a readable view, for example from:
{"Sensors": [
{
"TaskValues": [
{"ValueNumber": 1,
"Name": "Temperature",
"NrDecimals": 2,
"Value": 23.50
},
need to get
Temperature: 23.50?

Have you tested the csv option as suggested here: https://espeasy.readthedocs.io/en/lates ... ht=csv#csv
???

Yes, but I have an old version and is not supported csv.
I can not install the new version because the plug-in for the thermostat from here is used.

If possible

Code: Select all

What exactly do you want?
The json URL only outputs JSON formatted text.
The csv URL was added to output a string which was way simpler to parse on other devices without the need to interpret JSON.

So if you don't want to upgrade to a later version, then I don't know how to help here.
Unless I don't understand your question...

Or you parse the json output on the receiving platform, if you have the option of processing it using javascript or python, that's really easy.

So tnank you. Updated to the latest version.
But for some reason, the latest version does not add the _P159_Pushbutton plugin. The rest after being added to define_plugin_sets.h are displayed normally. And _P159_Pushbutton is not visible after adding.

Did you get that source from the Plugin PlayGround? Then it will only be included if PLUGIN_BUILD_TESTING is #defined, you might want to comment out the #ifdef PLUGIN_BUILD_TESTING line at the start of the _P159 source, and also the corresponding #endif at the end of that file.

I thought enough to put it in
// EXPERIMENTAL (playground) #######################
#ifdef PLUGIN_SET_EXPERIMENTAL
turns out to be wrong.
Ok thanks frend.

And now the error, commented out #ifdef PLUGIN_BUILD_TESTING и #endif
exit status 1
'SENSOR_TYPE_SWITCH' was not declared in this scope
When I added _P168_ThermOLED there was this error too, but I replaced
Device [deviceCount] .VType = SENSOR_TYPE_QUAD;
on
Device [deviceCount] .VType = Sensor_VType :: SENSOR_TYPE_QUAD;
as elsewhere and everything was compiled.

I think that's also a more recent change in the ESPEasy core source code.


Add: #include src/DataStructs/DeviceStruct.h

And append Sensor_VType:: in front of the SENSOR_TYPE_...

Like this: Sensor_VType::SENSOR_TYPE_SWITCH:

This add to define_plugin_sets.h or in 159_Pushbutton?

'SENSOR_TYPE_DUAL' was not declared in this scope
In event->sensorType = SENSOR_TYPE_DUAL;
add too
event->sensorType = Sensor_VType::SENSOR_TYPE_DUAL; ?

Yes, all SENSOR_TYPE_xxx should be prefixed by Sensor_VType::
