Hello @RosanaRufer good question and thanks @Robert.Wall for a comprehensive overview of the main dates. I drafted the following with links to some of the original blog posts that might be of interest

**History**

- [OpenEnergyMonitor.org](http://OpenEnergyMonitor.org) website first launched June 2009 [Welcome! - Blog | OpenEnergyMonitor](https://blog.openenergymonitor.org/2009/06/welcome). Open source electricity monitor designs developed and published alongside basic learning resources, some of which are still available in [Learn: Electricity Monitoring — OpenEnergyMonitor 0.0.1 documentation](https://docs.openenergymonitor.org/electricity-monitoring/).

- emonTx v1, 2010-2011 open source designs but never sold as a kit (Installed in 20 houses near us in North Wales as part of an local energy project).

- emonTx v2, emonGLCD and emonBase based on NanodeRF, March 2012 ([OpenEnergyMonitor Shop is open! - Blog | OpenEnergyMonitor](https://blog.openenergymonitor.org/2012/03/openenergymonitor-shop-is-open/)).

- Interestingly for historical purposes the first blog post on heatpump monitoring was 2 days after the shop open announcement [Heat Pump Monitoring - Blog | OpenEnergyMonitor](https://blog.openenergymonitor.org/2012/03/heat-pump-monitoring/). We’ve been at this longer than I remember!

- Pre-assembled NanodeRF base station October 2012 [Pre-assembled Nanode RF - Blog | OpenEnergyMonitor](https://blog.openenergymonitor.org/2012/10/pre-assembled-nanode-rf/).

- emonTx v3 & emonTH v1 November 2013 [New hardware is in the shop and starting to ship this week - Blog | OpenEnergyMonitor](https://blog.openenergymonitor.org/2013/11/new-hardware-is-in-shop-and-starting-to/)

- RFM69Pi v3, February 2015 [Introducing RFM69Pi V3 Raspberry Pi Expansion Board - Blog | OpenEnergyMonitor](https://blog.openenergymonitor.org/2015/02/introducing-rfm69pi-v3-raspberry-pi/)

- emonPi v1, April 2015 [Introducing emonPi: Raspberry Pi based energy monitor - Blog | OpenEnergyMonitor](https://blog.openenergymonitor.org/2015/04/introducing-emonpi-raspberry-pi-based/)

- EmonTx3 with ESP8266 (EmonESP) 2016 [ESP8266 WIFI developments - Blog | OpenEnergyMonitor](https://blog.openenergymonitor.org/2016/06/esp8266-emonesp-developments/)
