Hi, the following package is something I worked on for weeks and this has in fact worked just fine for 2 years. Since on off the last HA updates it does not work correctly anymore.
The package controls a Simple EVSE Wifi electric car charger.
When enabling the 2 scored out rest sensors, the charger will switch itself off, just 20-30 seconds after switching it on.
I have been disabling parts of the package in order to find out what exactly causes the issue. But no luck so far. It seems like doing multiple “getParameters” requests will fail. The issue is not related to the automations.
Does anyone know how to could limit the amount of “getParameters” requests and cache the data somehow and use that cached data to create the other sensors as a template sensor?
Given the time it took me to put this together I need some specific help, my programming skills are no that good 
#### Calling: http://192.168.207.98/getParameters gives me:
