I've been trying to understand why my program is buggy but I'm not sure if this behavior is normal. I have a Flow acquiring generated energy during the day. Inside a flow, I use an injection node to reset the total accumulated energy inside a function. The example flow is here . The problem is: I s…

[image] thalesmaoa: Inside a function, I use an injection node (1) ?? there must be a semantics issue here. The function node and inject node are two different nodes and you can not put an inject node inside a function node. Now if that is not what you meant, could you explain it again? (2)…

If you have an inject node that you think is not performing the inject, add a debug node showing the inject node output and set it to log to the console, then you can look in the log in the morning to see whether it is the inject node that is at fault or some other problem.

[image] zenofmud: (1) ?? there must be a semantics issue here. I edited the original post. Thank you. [image] zenofmud: (2) the example flow you point to is part of a a node's description but there are two flows - Here is a picture. [image] @Colin Indeed I already did that. I just …

Better to wait till it fails then look to see whether it was actually the inject node that failed or whether there is a flaw somewhere else. Post the code of the Store kwh node so we can have a look.

Ok. I will follow your suggestion: // Save payload var inputVal = msg.payload; // Create output variable var outputVal; // If receive a reset, save the last value as daily value if (inputVal == "reset"){ flow.set("DailyInv_energyVal", flow.get("Inv_energyVal")||0 ); }else{ // Continually…

Your pictures show 2 flows - each with a reset going into a function... If they are both resetting at the "same" time and writing to the same flow variable name then as Colin (sort of) suggests then the order those things happen could be an issue if one resets before the other and then sometimes (fo…

[image] Colin: Node context is safer if you only want to access the value inside that function node. Just did follow the example presented by the package writer. I will look into it. @dceejay Thank you! I will check that carefully as well.

I'm rushing at the moment, but a quick look at your function node code does not do what I think you want it to do. Firstly, the readings from the watt2kwh node should form a running total, starting at zero at midnight, then every energy feed reading should be added to the context value, right up to…

Hello @Paul-Reed , I have this variable that comes from the inverter that stores the total inverter energy since the day it was first power on. I was concerned about power loss or even communication fault. If that happens, I lost info and variables and finally the total energy generated. Thus I adde…

Is there a reason you have used flow context rather than node context? Node context is safer if you only want to access the value inside that function node. Then there is no possibility of something else accidentally writing to it.
Other than that I can't see any reason why it might not reset.
Hopefully when it fails the log may tell you something useful.
