LUA Script Error

Posted: Wednesday 06 September 2017 12:17

Hi @all
i've find this Lua script (sorry I don't remember where) for summing consumption from each sensor in one dummy sensor.
This script work fine but sometimes (every minutes) generate an error in LOG on the line 180.
Someone can help me?

Can you share the working one script. I have the same problem and can't solve it.

It has nothing to do with the script itself. You need to set the trigger correctly in de editor!

Sorry, but can you give me more info how to do that. I can't find where to set the triger for this script. This is the scrip that I use to compute Shelly 3EM total usage and it work and compute the total energy. But ger this error at some time. I think it trigger on changes of some power or energy device.

As I stated: In the Editor page, where you have edited this script you can define the Event it triggers on:
Set the appropriate event type as shown in the Wiki:

Thank you a lot. Finaly I find it :). I never seen this big box for trigerr choose for last 6-7 years of ussing Domoticz :).

Well it really is important to have a script only trigger with the right event or else your system will start doing things at the wrong times or get pretty busy! ;)

This is the only one script on LUA that I use and never seen that I can choose the trigers. Other some scripts that I use are writen on dzVents and all work well.
BTW I start to do all from the beginign before one or maybe two weeks. I update my domoticz (use it from 6-7 years ago) and it crash.
I have lots of mysensors 2,4gz + mysensors 866mhz + 433MHZ RFX (heat pump + UFH for my house + solar pannel for hot water + some energy meters). Now I start to install Shelly 3em and 5x 1kW inverters + 6Kw solar panels + 48V power wall. This project is still in progress.
Alll work well, but i never seen before, that I can to choose the trigers for LUA scripst. Thank you again!

p.s. Sorry for my bad English :)
