Pay-per-feed Billing (Starting 1st of July 2018)
We are working towards adding a pay-per-feed model for in order to fund server costs, maintenance and development.

The pay-per-feed model will likely be £1 per feed per year. If you buy or have bought hardware from the OpenEnergyMonitor Shop your account will be credited based on a percentage of total historic order spend, e.g a full EmonPi costing £153 will result in £31 (20%) of credit providing 5 years of free use for 6 feeds.

When you login to your accounts you will see projected costs and account balance over time shown on the My Account page. We aim to start billing on the 1st of July 2018 and costs accumulated between now and then will be reset at that point. Credit associated with past orders will be applied in full at this time following OpenEnergyMonitor shop email address verification.

We realise that a payment model will not work for everyone and are glad to say emoncms is fully open source and can be self-hosted, see the emoncms github repository. Our EmonPi and EmonBase energy monitors also come with emoncms pre-installed for easy local logging free of charge.

Backing up your data:
To backup your energy data use the guide here Emoncms backup also implements a daily data backup, you can check the status of your backup by following the steps here: check your backup data. In the event of server failure we currently expect restoration to take 3-4 days during which there may be loss of data posted during such an unplanned downtime. We will be working to improve this once billing starts.

Your data:
We will not use your data for advertisment purposes or sell it on to anyone else. You can port your data to another server and you can delete feed data permanently from the server as you require.
