"... How much will it cost?"

Here's an example:

You have an emonPi

OpenEnergyMonitor Shop

A current sensor + AC voltage sensor to monitor power

OpenEnergyMonitor Shop OpenEnergyMonitor Shop

Real-time data from the emonPi can be logged to a feed.

A feed allows you to view data recorded over a period of time.

In one feed, you might want to log the power used over time:

OpenEnergyMonitor Shop

In another feed, the kWh used per day:

OpenEnergyMonitor Shop

You will also have a feed for your temperature data:

OpenEnergyMonitor Shop

You have 3 feeds in total.

Because all the hardware was bought from
the OpenEnergyMonitor Shop,
you will have enough credits from your purchase
to last 10 years.


Hardware cost £162.59 ex VAT (£195.11 inc VAT) x 20% = £32.52 ex VAT (£39.02 inc VAT) of emoncms credit.

3x feeds at £1.00/feed/year ex VAT (£1.20/feed/year inc VAT) = £3.00/year ex VAT (£3.60/year inc VAT).

Credit will therefore last 10 years and 10 months.
