Help with the function node

No, we don't understand each other. I don't know why the translator translates it so imperfectly..
I'll try to write it like this:
1: temperature <80C, soc >80%, bat >=1400w - message "spirala1 1" (spirala1 ON)

2: the temperature, soc, power to the 1400w flashlight and also which spirals are switched on are checked, that is, we have spiral 1 switched on - the message "spirala 2 1" - (turns on spiral2)

3: the temperature, soc, power to the 1400w flashlight are checked and again which spirals are switched on, that is, spiral 1 and 2 are switched on, so the third spiral is switched on - message "spirala3 1"

temperature >80, soc >80 - all spirals OFF
temperature <80, soc <80 - all spirals OFF
temperature <80, soc >80 - Fastening spirals according to conditions

Why not take the tip from @craigcurtin do it the "node-red way"

it may simplify debugging to understanding what happens in the flow.

lebo potrebujem aby mi spínalo špirály na základe výkonu do batérie!Ked je vykon 1400W a teplota<80 a soc >80 tak zapne jednu spiralu.Ak vykon do baterie zase bude 1400W tak skontroluje podmienky teploty,soc a ktore spiraly su zopnute tak podla toho zopne dalsiu spirálu

Is it close now?
I expect the inject nodes to be replaced with Victron nodes.
I don't have a Victron to try it with, so inject the nodes.

I did something similar last year, for someone in France. See photo.

lenze mne ten kod co som sem posielal funguje ale stale posiela iba spravu aby zaplo spiralu1.A ked ju zapne tak sa objavy aj v context ale uz dalej nezopne druhu ani tretiu

When you start press input with 81 and input with 1401 and input with 79 then output 1 will be active. For each subsequent press on one of the 3 inputs, the next output becomes active, so after 2 more inputs, all outputs are active. Node Red is event driven.

Guys, I still haven't progressed with my problem. I've already modified it a bit and now it still sends an OFF message to the output. I sent the whole flow to Tuna, but I don't know how to write the code so that it turns on the spirals one by one under those conditions.

Did you try what I sent you?
It doesn't look like that.
So I pull out again.
Have fun with your project.
Sorry I couldn't help you.

guys, I've already managed to find out where the problem was in my function node.. Here the function node is modified so that it only sends msg.payload "spiral1 1" or "spiral1 0" and so on to the output. I thank those who tried to help me and gave me their time. I'm sorry that I can't communicate better.
