This topic is intended as a documentation change log for re-organisations, changes of location and significant content changes. **September 2021** - New Learn page on using multiple diverters: [Learn | OpenEnergyMonitor](https://learn.openenergymonitor.org/pv-diversion/usingmultiplediverters/usingmultiplediverters) - Update list of required libraries for use with the Arduino IDE: - Updated heat pump application guide to include new Pi based heat pump monitoring development board and video on heat pump dashboard. Associated documentation on the heatpumpmonitor github repository has also been restructured with documentation improvements ongoing. **August 2021** - Emoncms import/backup and upgrade documentation reorganised to remove duplication. **January 2021** - New Learn page on how to use the FTDI programmer (sold in the shop from January, 2021, onwards): [Learn | OpenEnergyMonitor](https://learn.openenergymonitor.org/electricity-monitoring/programmers/ftdi-programmer) - New consolidated page in Learn on how to use the Wicked Device / OpenEnergyMonitor programmer (sold in the shop prior to January, 2021): [Learn | OpenEnergyMonitor](https://learn.openenergymonitor.org/electricity-monitoring/programmers/wicked-device) **October 2019** - New Guide page on the Octopus Agile Emoncms app: [Octopus Agile - Guide | OpenEnergyMonitor](https://guide.openenergymonitor.org/applications/octopusagile) - New Guide page on the Emoncms Demand Shaper module: [Emoncms Demand Shaper Module (beta) - Guide | OpenEnergyMonitor](https://guide.openenergymonitor.org/integrations/demandshaper) - Updated backup module import/export documentation: [Import / Backup - Guide | OpenEnergyMonitor](https://guide.openenergymonitor.org/setup/import) - Updated Log Local documentation, note on local vs remote and new screenshots with v10 interface: [2. Log Locally - Guide | OpenEnergyMonitor](https://guide.openenergymonitor.org/setup/local) - Updated Log Remote documentation, note [emoncms.org](http://emoncms.org) pay-per-feed service and EmonScripts self-install option [3. Log Remotely - Guide | OpenEnergyMonitor](https://guide.openenergymonitor.org/setup/remote/) **September 2019** - New ‘Learn’ article: why can’t we use a single transformer to supply the power to an Arduino and to monitor the voltage? - [Learn | OpenEnergyMonitor](https://learn.openenergymonitor.org/electricity-monitoring/voltage-sensing/why-cant-i-use-a-single-transformer) **February 2019** - New ‘Learn’ article: a guide to installing the Arduino IDE on macOS (courtesy of @Jon) - [Learn | OpenEnergyMonitor](https://learn.openenergymonitor.org/electricity-monitoring/arduino-ide/macoside). **December 2018** - Other Utilities: Added new section to accommodate other utilities and applications not primarily concerned with electricity monitoring - [Learn | OpenEnergyMonitor](https://learn.openenergymonitor.org/other-utilities/water-and-gas/introduction). **June 2018** - Gas Monitoring: Added circuit diagram for 3.3 V version of the optical counter, see [Learn | OpenEnergyMonitor](https://learn.openenergymonitor.org/electricity-monitoring/pulse-counting/gas-meter-monitoring) **May 2018** - Added I.S.
