5 monthsMikeMills (133): * Dynamic rollups in SQL fix for time zones that don't match what's in the component definition * Query result grid fix for displaying issues when some column results don't have names

User Administration

JLS

1 monthMikeMills (133): Not today, but it seems useful, so we are adding the Last Sign In date/time to the Organization Users list in Observation studio in the next patch.

Long Story

7 monthsMikeMills (133): MQTT is on the roadmap. We've been waiting for someone to request it. We can slam it in if it's not too much work or doesn't require adding servers (at least initially). I'll send you a private message in the forum.

GS SQL Query Objects

MikeMills

1

8 monthsMikeMills (133): We have created Query objects that are located under the tools tab: https://e3effa51eee72fd900e3-2fb779bd12ec72d4612275342f2c9187.ssl.cf1.rackcdn.com/a3124f688ceccd547c6b690c4354b6d0.png Queries are useful for long running GS SQL (displaying cached results are fast), queries with large result sets, queries that need to be run at a certain time. Queries can be defined, saved, secured, and scheduled. Results are cached on the server...

Chart with X-axis spaced according to timestamp, not equal spacing

Nahanni

2

8 monthsMikeMills (133): I think you need to fill the spaces between with time/values to get what you're after. I'm guessing you're graphing a Regular stream. You could graph an Interval stream to fill all of those missing times. An interval stream has a value for all time intervals. Your in-between intervals will be null since there is no actual value. Your stream definition has a default rollup calendar. It's cycle intervals will show in the line chart dashboard...

GET feedrequest for specific streams

2 yearsJefft41 (1): I'll give that a try. Thanks Mike!

GET Request to get data from all streams and components

giorgos

2

2 yearsMikeMills (133): Try doing this: * Get a list of all components. See GET Component: https://www.grovestreams.com/developers/apicomp.html * Loop over components and get all the meta data for each component stream. The meta data will include the startDate and endDate of each stream. See Get Component/{uid}?forQuickView. Set the startDate and endDate both to zero to prevent bringing back samples: https://www.grovestreams.com/developers/apicomp.html * Now loop...

Smartthings integration

Josephny

2

2 yearsMikeMills (133): I don't think there is an simple "auto-populate" way to do it. We have this tutorial: https://www.grovestreams.com/developers/getting_started_smartthings.html That tutorial is getting old and may not be accurate anymore.

Error A JSONObject text must begin with '{' at character 1

pat

3

2 yearsMikeMills (133): The JSON format looks correct. The error seems to indicate that what is being passed to our JSON decoder doesn't start with a "{". My guess is either nothing is being passed in or the first character is a hidden character you're not seeing in an editor such as the encoding token. You might want to use an editor that displays all hidden tokens to make sure. Check your system notifications and see if the error includes the JSON...

Plot multiple components on the same map

pat

2

2 yearsMikeMills (133): There are two map widgets to select from. One that only tracks one component and another that tracks all of the components within the viewable area (bounding box). Does the bounding box map widget do what you want?

unexpected change in graph line from step to "direct"/non-step

ero4444

3

2 yearsero4444 (1): I see what is happening now. The COV/change-of-value/resolution was 1.0F, now it is 0.1F. If I had zoomed in enough then I would see the steps, and the of course all the unexpected stream values are in in its table. The change must have occurred to only certain device types and their streams. Thanks for listening.

Downloading Data at Different Intervals

MThomas

14

2 yearsMikeMills (133): Can't think of another way today except for having the device upload every minute. Gap Filling only fills gaps as data comes in. We're working on a solution that will gap fill as data is queried for, but that will not be available for months.

How to get an alert if door is opened for more than 45 seconds ?

pat

2

2 yearsMikeMills (133): You will have to user derived streams and get a derived stream to derive automatically at the current time. See this thread: https://forum.grovestreams.com/topic/494/gap-filling-forward-to-current-time/ Also search for "kicker" in the forum. Your logic can compare the source stream for a 1 and track the SAMPLE_TIME. Then use time()-SAMPLE_TIME to get the number of milliseconds that have passed. Setup an event/alert on the derived...

Backup Orgaization Python Script

MikeMills

3

3 yearsMikeMills (133): One of the User's Groups must have Manage Exports capability and the user/group must have Traverse rights for the content store folders and objects (Components, Content, Tools) they are backing up. Right click on the store folders, choose properties, and check the security tab. Aren't there errors in the Org's System Notifications when the zip file is empty? We did some work in this area last week to improve backup times. We could've...

Best way to temporary stop access to Grovestreams

pat

2

3 yearsMikeMills (133): You can only restrict access to organizations and there's no easy way to popup a message. That being said... If I were to do it today, this is what I'd do: 1. Create a User Group with no Capabilities and add all users to that group. Remove them from other groups. 2. If you subscribe with the "Business Pro" plan, you could also add the Group to each Root folder and Deny Traverse rights. Instead of a Popup, you could possibly rename...

Derivation changes.

MikeMills

3 yearsMikeMills (133): * Auto Recalc on any derivation changes: https://forum.grovestreams.com/cached/f4d777e0a0454c0d3ffbcdd295027838.png Derived streams will be totally recalculated when this switch is on and any changes to derivation settings change including variables and the expression. * Reconcile Lock on Component Template Streams. Lock this in the Template editor. When reconciling (for pricing plans that support this), the component reference will...

Removed Component Studio

MikeMills

1

3 yearsMikeMills (133): All component studio objects have been moved into Observation Studio under a 3rd content store called "Tools". https://forum.grovestreams.com/cached/c807d5423541a8cda6f09f6206cf1781.png User/Group security can be set on all Tools folders if your pricing plan supports role based security.

OAuth 2.0 Authorization code grant?

glyde_lab651

3

3 yearsMikeMills (133): We've done this. OAuth 2.0 authorization is a good way to not hard code an api_key on devices. With OAuth 2.0, a device gets registered by the user and it holds onto an authorization token and a refresh token and uses those for secure access api calls. Amazon Alexa now uses our OAuth 2.0 authorization servers. More information here: https://www.grovestreams.com/developers/oauth.html

Add/Remove Action Event via API

MThomas

2

3 yearsMikeMills (133): Yes. Many of our APIs are documented but the best way to know and learn them is through the Web UI since it is built with the API. Open Chrome, Hit F12, watch the Network debug tab to see api calls made and what is returned (Usually JSON). Watch the calls made while performing them in the UI such as creating or editing an event action on an event action package.

Send URL in email notification

fixingthingsguy

6

3 yearsMikeMills (133): Email sending has been slow lately (like 20 minutes to get an email). We use an Amazon AWS email service and it started throttling us lately because our daily email numbers are becoming large. We've put in a request to increase our Amazon email quotas. It should be resolved soon.

Improved Mobile Website Navigation

MikeMills

3 yearsMikeMills (133): Added a navigation selection list after entering an org from within the Mobile website: https://forum.grovestreams.com/cached/2dda0ae4d93d49cd6095f5ca97552ede.png Added security Group capabilities to restrict what Mobile users see in the list of options: https://forum.grovestreams.com/cached/f13c230a7dd4e54b89ef6baac8786db0.png If there is only one capability option selected, then the navigation screen will be bypassed and the user...

Apply the Same Dashboard to Multiple Components

MikeMills

1

3 yearsMikeMills (133): A common dashboard can be associated with many components within the Component Definition: https://forum.grovestreams.com/cached/690ff8e678a05147c86451e3ed44999a.png The dashboard will be displayed when a component is viewed within the GS Mobile website (instead of the default component/stream viewer). When the dashboard is viewed by choosing a component: * All of the streams within the dashboard will be replaced by streams within the...

Graph cumulative data

tokp

4

4 yearstokp (1): Perfect, got it to work as long as I used the reset cycle set to none which is fine since I can reset every year. "To force the Derived stream to fully recalculate - right click on it and select "Delete all time series data". Then wait for a minute or so." - I am glad you included that, I have been waiting a day to see data come in to check my derivations. Resetting speeds up my testing a lot! Thanks for your help

Calculate dT/dt

Terp

4

4 yearsMikeMills (133): @Trakk "And the last temperature logged at those times." Getting the last temp for the Day or Hour is easy. Choose a Day, or Hour, cycle with the LAST function. This will return the last sample value for that cycle. You can choose Cycles and functions (min,max,sum,last, ...) in Dashboard widgets or in a derived stream expression. "I want to be able to get the total on time each hour of the day." I'm still thinking about...

Data storage period

fisa7

2

4 yearsMikeMills (133): Unlimited time if configured correctly. Data retention will default to 2 years via the "Delete Profile" selected by a Stream's definition. Change the Delete Profile to retain the data longer: 1. Edit the component, choose the stream, select a different Delete Profile 2. Change the new-stream-default: Admin-Organization-General Settings-New Stream Defaults

dashboard/graph/settings/data/"apply expression" to stream of binary.

Derivation error - why?

ctmorrison

4

4 yearsctmorrison (10): Not what I was doing -- at least I had no intention of doing this. The new stream I created looked identical in all ways to the one that was throwing errors. Kind of academic at this point -- I already deleted the "bad" streams. Thanks

Event stream change?

ctmorrison

3

4 yearsctmorrison (10): Hmmm...I had already fixed the issue to avoid nuisance alerts, but I still am uncomfortable with what happened. We'll see if it happens again.

Import data from and old component to a new component

pat

3

4 yearspat (1): HI, Yes sorry for that question. It was because I had a component_template filled in one case and not in the other case. So it was creating a new component instead of feeding the previous one. -> Method 1 is the good one ! Thanks

Local SQL database

edwar210

2

4 yearsMikeMills (133): You'd have to use our API to pull from GS and Push into a SQL database. Or if the SQL database has some kind of HTTP interface, you could setup a stream data Arrival event to make the HTTP call with the new data into SQL.

Smartthings API errors

TravCam

3

4 yearsTravCam (1): Actually, my issue began on organization setup... I didn't have those API options because I apparently selected No Blueprint in advanced tab. Deleted my org and followed defaults and then the proper API options materialized... Thanks!

Display Last Sample Time

Josephny

5

4 yearsMikeMills (133): You can't edit it in the mobile site anymore? Did you attempt to edit it in the studio and save it? If so, it will corrupt the dashboard.

my esp8266 code doesn't work

nab96

2

4 yearsMikeMills (133): Use GS API tracing to see if your call is even making it to your GS organization. Also, check your organization System Notifications for any errors. Our web server logs indicate that your call is not even making it to our web servers. This can indicate several potential problems: 1) Your URL is not formatted correctly. Trace it out to the debug console window and paste it into a URL validator website to ensure it is a valid URL. 2) Your board...

Uploading historical data via PHP

JoEmbedded

2

4 yearsMikeMills (133): I think Unsupported Media type means the content-type header needs to be set. Try setting the header: content-type:application/json Here's a GS Python example: https://www.grovestreams.com/developers/getting_started_helloworld_python.html

4 yearssfm (1): can I have the code for uploading data with ESP8266, please?

Create component from Template

crevicedweller

3

4 yearsMikeMills (133): To create a component with all of its known streams at the same time when a component makes its first call, just set the compTmplId parameter. If you want to create a new stream based on a template stream after a component has already been created use both of these parameters in the URL: dtId dsId From https://www.grovestreams.com/developers/api.html : These parameters are used to dynamically create streams for a component if they do not...

Stream Data I/O blocked even though no data was sent

Eugene

2

4 yearsMikeMills (133): All I/O is considered. This includes when you leave a dashboard open with a fast polling rate. See this thread: https://forum.grovestreams.com/topic/65/page/1/what-are-billable-transactions/ Email us at our info or support email address (include your GS account email address) and we'll reset you're data I/O so you can keep going.

httpie PUT failed

kevin

5

4 yearsMikeMills (133): I don't think we'll accept a x-www-form-urlencoded type. Maybe try not setting the content-type to see if anything will get through. Usually, 401 will indicate that your api_key is invalid or we can't parse the URL to get extract the api_key. But... I searched our server logs for "compId=Sensors&temp=24.5" and nothing came up so I don't even think the call is making it to our servers. Try it again with a compId to something...

4 yearsAvocadodude (1): Thank you for all the help! There was a parameter in the Gateway called "Offset from GMT in minutes" and it was set to an odd value. I set it to '0' and all is good now and reads the correct time in my timezone.

4 yearsJLS (1): Thank you Mike, this worked great!

Modifing Arduino example template

OldNerd

7

4 yearsMikeMills (133): Ensure that the value the device is passing up is compatible with the Stream Value Type. For example, it might be passing up "10.3 C" (as a string) and the stream has a value type of FLOAT. It won't be able to convert "10.3 C" to a float. It could convert "10.3". That could be why a reconcile is failing. Just a guess.
