Glenn,

That sounds great, thanks.

If the tariff’s in a user defined variable, it should be possible, using Indigo’s actions and schedules, for anyone wanting multiple tariffs to modify the variable outside of the plugin.

More thinking out loud follows!

Yep - could use a variable or set up a plugin command to change tariff.

Issue will still be calculating.
Single tariff is easy - can use the enphase reported WattHours for today/7days/lifetime for cost.
Simple WattHours x tarrif == new $ for the time periods
Enphase saves and can be easily repopulated/calculated if/when plugin restarted.

If Time of use/variable tariff - then this data reported by enphase doesn't help at all, and I don't think can be used.
The plugin would likely need to hourly calculate Watts Hours used in that hour (check how to) and check a user-defined schedule and then save that data away from Indigo so isn't lost on restart.
Would then need to read back in on restart to recalculate day/week/month totals...

As a first start...

Try
https://github.com/Ghawken/IndigoEnphaseEnvoy
Click the clone/download button and install 0.2.0

Create your own 'Enphase Cost Device'

Should populate with $.cents cost per day/7 days/consumption/production and approx net.
Tarrif selectable within device in dollars/cents (e.g. 0.44 cents per kWh)

Quick first attempt as limited time - but if device not created will not affect the plugin at all.

Re: Enphase Envoy-S Solar Power Plugin (with Panel Monitorin

Thanks Glenn!

Loaded V0.2.0 and works OK. Appreciate the time!

However, I'm unsure which tariff I should be using (import or feed-in)?

I was contemplating that the two tariffs would be entered so that a comparison could be made. However the current cost device allows the "avoided cost" of solar production to be calculated - a good start!!

Like you, I'm a little busy at present, but if I have a brilliant thought(s) I'll let you know!!

Thanks again for the time you've spent and for this plugin.

Thanks.
Not sure as I’m on time-of-day tariff - so doesn’t really apply to me.

But I can easily add different tariffs for the consumption/production and/or net $ - if that makes any sense for you.

Hi again

Try 0.2.1
Some tidying up - hadn't converted all to kwH accidentally.
Also have added consumption tarrif and production tarrif as seperate device variables.
Also add netKwh7days and netKwhToday to device

Re: Enphase Envoy-S Solar Power Plugin (with Panel Monitorin

Hi Glenn!

Finally made it back to my computer and downloaded latest release - but shows up as 0.2.0 that I already had. Tried downloading zip from Github with the same result.

Any ideas?

Got it thanks, Glenn. But work’s getting in the way of exploring the cost device in detail
