+details & sum
+=============
+
+Example
+-------
+
+	https://server.tld/details?sensors=4,8,2&time=T1:T2
+	https://server.tld/sum?sensors=4,8,2&time=T1:T2
+
+Description
+-----------
+
+`sensors` is a comma separated list of sensor ids the user wants to inquire
+information about. When supplying an empty value for `sensors`, data for all
+sensors is returned.
+
+`time` is a colon separated value of two unix timestamps T1 and T2. The special
+value -1 exists to denote and open interval to either side. `-1:-1` requests
+data of all times and so does a query without the `time` parameter. The time
+values T1 and T2 form a closed interval. When supplying an empty value for
+`time` is the same as supplying `-1:-1`.
+
+Hence, the following query would return everything the server has on all
+sensors and hence are equal:
+
+	https://server.tld/details
+	https://server.tld/details?sensors=&time=
+	https://server.tld/details?sensors=&time=-1:-1
+
+Example output:
+
+	[
+	 {"id": 1, "name": "toaster", "status": "active", "values": [
+	  {"begin": 1317470289, "end": 1317470312, "value": 1.3234},
+	  {"begin": 1317470312, "end": 1317470678, "value": 7.123}
+	 ]},
+	 {"id": 2, "name": "fridge", "status": "active", "values": [
+	  {"begin": 1317470289, "end": 1317470312, "value": 0.12},
+	  {"begin": 1317470312, "end": 1317470678, "value": 7.123},
+	  {"begin": 1317470678, "end": 1317471421, "value": 1.354}
+	 ]},
+	 {"id": 3, "name": "oven", "status": "active", "values": [
+	  {"begin": 1317470312, "end": 1317470678, "value": 1.3234}
+	 ]}
+	]
+
+If a query cannot be satisfied (sensor id doesnt exist, no data exists for the
+desired timestamps, sensor is blacklisted) the server will silently fail and
+just send an empty "values" dictionary or as much data it can satisfy the query
+with. It is the task of the client to verify the returned information for
+completeness.

+Description

+
+`sensors` is a comma separated list of sensor ids as in the other queries.
+
+The return is a list of the (un)blacklisted devices as in the `list` command.
