v2.2.0

EmonHub version 2.2.0 is now available in the stable branch. The latest version brings several new interfacers to read data from different sources including:

• Improved SDS011 Particulate Matter Sensor that puts the sensor to sleep between readings in order to extend the lifespan of the sensor, thanks to @DanBates

• New interfacer to read data from a SDM120 Single phase MID certified DIN rail meter via Modbus. This has been added with heat pump monitoring applications in mind were MID certified monitoring is required for both electric and heat.

• New interfacer to read from MBUS meters, this requires a MBUS to USB converter that we will be stocking in the shop soon. This is designed for reading data from heat meters such as the Sontex 531 (again with heat pump monitoring in mind) but the implementation is fairly generic and should read from a wide variety of MBUS meters.

• New interfacer for reading directly form DS18B20 temperature sensors connected to a RaspberryPi similar to https://pimylifeup.com/raspberry-pi-temperature-sensor/

• New interfacer to write latest sensor values (or emonhub cargo objects) to redis keys. Makes it easy to then pick up the values in a separate python script used for automation, not sure if this will be that useful generally but it was something I needed.

• New interfacer called EmonHubOEMInterfacer that will replace the EmonHubJeeInterfacer designed for use with new continuous monitoring firmwares that @Robert.Wall has been working on. This needs a separate post to explain in more detail once we launch all of the new firmware's. More to come on this later.

• If you missed it from previous updates, thanks also to @borpin for a new pulse counting interfacer. This can be used for pulse counting directly on the RaspberryPi.

There are also a number of bug fixes, thanks to @borpin, @bwduncan and @alexandrecuer

A new page has been added to the integrations section of the guide called EmonHub Interfacers intended to cover mainly integration with other hardware rather than the core interfacers used by OpenEnergyMonitor hardware. Links above link to the relevant sections of this page.
