Saved on imports #131

Open menaibluey opened 3 months ago

I'm seeing massive amounts of saved on imports within a very short time. What could be the reason for that? My tariffs are $0.3 for import and $0.07 for export. Would appreciate your guidance whether this is an mis-configuration. image

Looks like your electricity price is per MWh where the battery is expecting per kWh so you would be a factor of 1000 out. I would guess the kWh price would be 0.21 I'm not sure if that's the whole problem, but it would be the first thing to look at.

Thanks for your response. Here’s my import tariff config for import. I’m assuming that this is $ per kWh in my case, so 30 cents per kWh. Similarly my export tariff is 7 cents or $0.07. Is this the correct config for the tariffs?So it appears that the import and export sensors are reporting in Wh hence the discrepancy. I will create sensors that report in kWh so this should fix it. Should have checked this before complaining. Please go ahead and close this issue. Apologies for wasting your time. Sent from my iPhoneOn 4 Jul 2024, at 06:51, hif2k1 @.***> wrote: Looks like your electricity price is per MWh where the battery is expecting
