[OpenTRV-dev] import of openTRV stats to OEM

Highcharts is another possibility: http://www.highcharts.com/ 

MQTT, EmonCMS and Node-Red (and even RRDtool) are the tools that I keep
returning to.

Here's a timely post from Glyn @ Openenergymonitor:

The TP-Link micro routers (e.g. TL-MR3020 or TL-WR703N) running OpenWRT are
a convenient way of providing power and comms to a Rev2 board (using FTDI to
USB cable). Optionally, some pre-processing of the data can be done on the
router using awk before posting to MQTT, EmonCMS or elsewhere.

I've got a bit of experience with this (I'm logging some
Ciseco/WirelessThings temp+humidity sensors to EmonCMS - by extending
"EmonHUB" to support JSON sources and sinks), and I'm also developing a
custom data presentation "app" for EmonCMS at the moment).

The JSON import into EmonCMS is a little bit underused and has a few quirks
(nothing serious).

For the gateway box (i.e. the EmonHUB or whatever one), I think something
running OpenWRT might be a good idea - OpenWRT has the advantage of
supporting a very large variety of hardware (from the NSLU2 on one end up to
AMD64 boxes at the other extreme, and taking in the Raspberry Pi on the
way), is well suited to embedded/headless operation, and includes a decent
Web UI framework too (LuCi).

I've also been wondering if there's something other than EmonCMS which I
should be using, and have been meaning to look into others.  These are one
ones I know about already (without having done any "extra" research):
