Total Energy Calculation
This example implements the summation of 5 energy measurements into a Total Energy (Calculation Result).
Total Energy Device

Total Energy calculation is triggered using virtual switch.
Total Energy calculation testing is easy when rule is triggered using virtual switch.
Here is an example of how to set a virtual switch on the first day of the month (after midnight with a 5 minutes delay).

"name": "Month First Day Set VSwitch",
"actions": [
{
"every": {
"specific": {
"day": 1,
"reference": "Midnight",
"offset": {
"value": {
"integer": 5
},
"unit": "Minute"
}
},
"actions": [
{
"command": {
"devices": ["-- ID Virtual Switch Device --"],
"commands": [
{
"component": "main",
