You might be interested to learn that ISO/IEC JTC 1 has just established
a Working Group (WG 10) to work on standardization in support of the
Internet of Things (IoT).  WG 10 has just been established and has
not yet begun any actual standardization actions, but is likely to get
started in earnest within the next two or three months.  I cannot
predict what WG 10 will do, nor how successful it will be, but it will
certainly have participation by a great many of the big players in the
IoT arena.  I would guess that the first activities of JTC 1/WG 10
would be generating a "reference architecture" for IoT, after
which they will either propose that existing subcommittees (SCs) in JTC 1
pursue standards in specific areas or perhaps write those standards
themselves. 

Those of you who are interested in this activity might consider
discussing with your ISO National Bodies (e.g., ANSI, BSI, DIN) getting
accredited to attend the WG 10 meetings as an individual expert.

Hope this helps,
   Jim

Having worked on a system that supported several 100 different devices I know some standardization could sure help.  The actual contents don't necessarily need to be standardized but standardized containers, protocols, and schema / meta languages sure would help.  Something like EXI would have made out jobs way easier...

Some of the manufacturers (in the satellite world in particular) also make a tidy profit by supporting their own gateways or more fully featured service endpoints to do conversions from some proprietary binary format to something like XML. For example, Digi will be happy to charge you a dollar (or maybe less) per device and give you a cloud based API with persistent storage behind it. Seems cheap until you do something like put a couple of devices in every office in a couple dozen buildings. You can usually roll your own handlers for the binary formats, there are usually some docs, but the XML formats are trivial to implement.

I'm not sure there's much to be gained from standardizing sensor data

formats as a whole.  Standardizing time, quantity, and unit pieces might

be worthwhile, but I don't see a point in trying to create a generic

"sensor data" format.

Thanks,
