Gettign the value from a temperature device in a python plugin

[akamming]

Hi,

i am trying to write a python plugin which derives the needed boiler temp from an outside temperature device

however i cannot find a way how to get access to a temperature sensor which was not created by the pluing (e.g. i have a idx number from the temperature sensor, how can i get the value of that sensor in a python plugin)

Does someone have some sample code i can use?

A plugin can only see its own devices. Is really a plugin you need ? Or a python/lua/dzVent script would be better ?

Otherwise you can use jsonnAPI inside the plugin ( which I don’t think is great)

Tx. i could fix with a python/lua/dzvents script, but i really like the fact that the plugin creates and manages it's own devices. Saves a lot of manual work creating the virtual devices.

I already used the json API as a workaround. It works, but requires that the plugin know the IP Adress and port from the domoticz instance. It is now a configurable parameter in the plugin, but it would be better if this could be retrieved from the domoticz config within the python code. Does anyone know how?

A lot of work?
Takes about 20 seconds per device (if you type as slow as me)

and multiply that by 25 virtual devices

besides now i don't get error's on this script if i accidentally delete a device, it is recreated by the plugin.

I had the same concern and created a topic : viewtopic.php?f=65&t=35121

Getting access to other devices state with read only access from a plugin would be very useful.

A plugin is only to be used to create and control the related hardware. Of you want to control/modify devices based on other devices you need scripting like Blockly, Lua, DzVents etc who have a view over all Domoticz devices.
If you accidentally would like to use one then the http API way of working would do.
It is the same for C++ Hardware plugins I presume.
