Access S0 Power (and Energy) values in Rules to calculate (correct) COP?

[JohnDow466]

Will it be possible to access the S0 Watt and Watthours values in Rules (similar to the Dallas 1-wire temperature values) to calculate (more correct) COP values?
thx

@CurlyMoo would this be easy to add?

What should the implementation look like?

[IgorYbema]

Something in the same line of ds18b20#2800000000000000 but then for S0.
Like:
s0#watt_1 = current watt seen at S0 port 1
s0#watt_2 = current watt seen at S0 port 2
s0#watthour_1 = amount of watthour seen at S0 port 1 since last report
s0#watthour_2 = amount of watthour seen at S0 port 2 since last report
s0#watthourtotal_1 = total amount of watthourtotal seen at S0 port 1
s0#watthourtotal_2 = total amount of watthourtotal seen at S0 port 1

@IgorYbema Do you already feel confident enough to implement this yourself now?

[IgorYbema]

I think I got it: IgorYbema@729b923

Nice!

1. I do think that you overly check the variables.
2. I also believe that the strrchr isn't necessary. Just pick the number from key[4] and check if key[5] is also a number. The latter shouldn't be true.
3. I would also already check the total allows stringlengths in #476.
