This can be used to get the most recent current readings from compatible devices that are being managed with T&D WebStorage Service.
It is possible to get the same list of current readings in the "Data View" window of T&D WebStorage Service.
*Note that info about and related to warnings is not included at this time. We are however planning to include warning information in future revisions.

Read-Only ID is also possible
10 requests per allotted 2-minute span
When automatically uploading data to T&D WebStorage Service, the shortest possible uploading interval for devices such as TR-7wb/nw/wf is 1 minute.
We have designed the API so that it is possible to get the most current readings from devices like this which refresh every minute.
The rate limit allows for gaps in timing between devices, but we calculate that in most cases almost all conditions will be covered if current readings are retrieved from 2 to 5 times within a 2-minute period.

| Host | api.webstorage-service.com:443 |
| Content-Type | application/json |
| Parameter Name | Format | Required | Default Value | Details |
|---|---|---|---|---|
| api-key | string(45 characters) | Yes | --- | Already acquired API Key |
| login-id | string(8 characters) | Yes | --- | User ID Read-Only ID is also possible. |
| login-pass | string(4-16 characters) | Yes | --- | The password for the above User ID. |
| remote-serial | Array: string(8 characters) | --- | Make entries here when wishing to select by using one or more Remote Unit Serial Numbers. It is possible to specify multiple units by using more than one array. (*1) | |
| base-serial | Array: string(8 characters) | --- | Make entries here when wishing to select by using one or more Base Unit Serial Numbers. It is possible to specify multiple units by using more than one array. (*1) |
(*1) For both “remote-serial” and “base-serial” it is possible to specify multiple units. However do not specify by using both “remote-serial” and “base-serial” at the same time. Make sure to specify by using only “remote-serial”, by using only “base-serial”, or by using neither of them to specify.
When specifying by using “remote-serial”, you are already specifying a base device and hence it is not necessary to use “base-serial”.
If specifying by serial number, even if only one serial number is specified make sure to describe as an array. (Please refer to the Request Example below.)

* “Independently operating devices” refers to such devices as in the TR7A2/7A, TR-7wb/nw/wf Series, TR4A Series, and the TR-700w series which can send data to T&D WebStorage Service acting alone without a Base Unit.
