We are thrilled to announce that the emonPi3 and emonTx6 are now officially available in our shop! 
These models succeed the emonPi2 and emonTx5. While they maintain the same functional experience, they feature a significant microcontroller architecture upgrade under the hood (Microchip ATSAMD21J17). This shift provides a more robust, future-proof platform with improved configurability.
A huge thank you to the team who made this happen:
- Hardware Design: @awjlogan
- Firmware: @awjlogan @FredM67
- Testing & QA: @Robert.Wall, @borpin, and @rupert
Brief System Overview
emonPi3
- 6-channel AC electricity monitor using clip-on CT sensors and an emonVS voltage sensing power supply (single & 3-phase) .
- Integrated Raspberry Pi running Emoncms for local data logging and visualisation
- Optionally post to our cloud Emoncms.org server.
- Receive RF data from other wireless nodes e.g emonTH wireless temperature & humidity sensor and emonTx on 433.92 MHz*
- Support for multiple wired DS18B20 sensors
- Home Assistant Integration
* By default, the emonPi3 & emonTx6 use the 433.92 MHz ISM band, this is not backwards compatible with our existing hardware which use the 433.0 MHz band. However, it’s possible to update the firmware on existing hardware e.g emonTH2 and emonTx4/5 to use the new 433.92 MHz frequency or set the emonPi3 & emonTx6 to 433.0 MHz.
emonTx6
- Wireless expander node
- Expand an emonPi3 system with an additional 6-channels of AC electricity monitoring (single & 3-phase)
- Either share a single emonVS voltage sensing power supply with an emonPi3 using a splitter or use a 2nd emonVS if emonTx is in different location
- Transmit data to emonPi3 via 433.92 MHz wireless or direct USB connection
- Support for multiple wired DS18B20 sensors
- ESP Home Integration with Home Assistant** thanks to @FredM67
** emonWiFi hardware coming soon to support easy ESP Home HA Integration.
The setup guide and documentation for the new hardware is available on the docs
As always the hardware and firmware are fully open-source
