26 daysMikeMills (130): * A new video tutorial, created by STMicroelectronics, for How to get started with STM32 Cellular to Cloud discovery packs (P-L496G-CELL01, P-L496G-CELL02). The good part, registering with GS, is at about the 16 minute mark: https://www.youtube.com/watch?v=b2-37F7wcaI&feature=youtu.be

Modifing Arduino example template

OldNerd

7

2 monthsMikeMills (130): 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.

Historical tracking

2 monthspat (1): :eek: WHAT A BIG CHANGE ! Looks good and the time range works also with the map. I like it. :)

Component IDs must be unique

pat

8

3 monthsMikeMills (130): Usually creating a component is fast - a few milliseconds, but you're creating it with a lot of streams so it could take longer like a second or two. Issues with the network between the device and GS could occasionally add time too.

ESP8266 PUT method doesn't work

The_Doctor

3

3 monthsThe_Doctor (1): Thanks! It already works. The problem was with the missing two "nn" at the end of the PUT command. This code string below is working example. [code]ESP8266_SendData("PUT /api/feed?api_key=secretKEY&compId=bath&data=29&data=66 HTTP/1.1nHost: nConnection: closenContent-Type: application/jsonnn");[/code] Hope it helps another programmers which don't use 3rd party libraries.

Reduce data consumption

Henrik

3 monthsMikeMills (130): Maybe this thread will help: https://forum.grovestreams.com/topic/65/what-are-billable-transactions/ Big things: * decrease the data being uploaded/downloaded. Try making your device stream IDs short; instead of an ID of "temperature", try "t" . * Don't leave dashboards open with a fast refresh rate (like every 5 seconds). * Decrease the interval time the studio looks for new notifications (Org Studio - Admin -...

Read user only

pat

2

3 monthsMikeMills (130): You can make Observation Studio read-only but it requires subscribing to the Business Pro or Enterprise pricing plan. Under those plans, a user can right click on folders, dashboards, maps, and components and configure the rights on them. One right is Read-Only. More information can be found here: https://www.grovestreams.com/downloads/guides/GroveStreams%20Access%20Permissions.pdf

5 monthsMikeMills (130): Here's a graph of daily average derivation runtimes. Code improvements and adding more servers sped things up. https://forum.grovestreams.com/cached/63b3c8b3c421e1fa2a554d4a5b105dab.png

Incompatible streams

5 monthsctmorrison (10): Nice tip on telling the difference! I've always wondered if there was a way. They are, in fact, different types. I'm not sure why I wasn't consistent, but...

Value expression help

Josephny

2

5 monthsMikeMills (130): Yes, possible. If you are asking to graph the daily amount Remaining this is how you can do it: - Edit the widget (click the menu button in its header) - On the first tab, select Range Type Heartbeat; View Last 30; - On the data tab, select the stream; Select Day for cycle; Select Last for the Statistic. This will cause the graph to display the ending % for each day - On the same data tab, select the stream; On the properties panel, edit...

5 monthsfixingthingsguy (4): So here is a little more meaty stuff to guide you. Best to have the link I sent (analyticalphysics.com). I entered this skill info as is: Extracted.... Every skill requires an intent schema with at least one defined intent. The following minimal schema is sufficient for a functional skill: { "intents": [ { "intent": "Help", "slots": [] } ] } Apparently intents need not include the word “intent” in...

6 monthsAvocadodude (1): Ok. I'll figure something else out. It does work in that widget if I feed it numerical value. https://forum.grovestreams.com/cached/795667f15d09a12f3ffdacab1f861a01.png

Smartthings and monoprice motion sensor

7 monthsKylJoy (1): It worked for me to set the component ID to the device label from the Smartthings device as shown on the Smartthings develper site. Then, temp and motion streams auto-filled.

Issue with "connect gaps"

JChristensen

7 monthsJChristensen (1): Thanks, Mike. Makes perfect sense. My stream is just a regular stream, not an interval stream. Hope all is well at GroveStreams, Happy New Year!

Any way to filter a table?

orbitcoms

2

9 monthsMikeMills (130): Take a look at the pivot table widget too. It allows for some filtering and sorting. Filtering can also be done via derived streams. Derive a stream that is a filtered result. We don't provide a pull down to select the date range directly in a dashboard widget. The range can be selected via the widget edit options.

Sending POST data

ctmorrison

2

9 monthsctmorrison (10): OK...I may have figured it out. From one of your examples, I noticed the "content-type" header being specified and tried it. It appears to have worked. Still testing.....

Derivations - current period

ctmorrison

5

9 monthsctmorrison (10): Sorry -- forgot all about this. What I want is the current cycle of the stream being derived. I'm trying to use the "latency" feature of the digital widgets and turn them white and set them to zero when the data is more than 30 minutes old. I've done this countless times in the past, but I may have switched from Interval Streams to Streams without understanding this impact.

Send URL in email notification

10 monthsfixingthingsguy (4): Thanks for the precise steps. Works just like you documented. And I also have noted the way to get around any IT restrictions on sending URLs to use when the situation arises. Regards

Pivot Table Beta

MikeMills

5

10 monthsMikeMills (130): @christnufc - Sorry for the long delay for a reply. We've been thinking about this one and whether we can do a simple enhancement to allow this. It doesn't seem like this is possible today without a significant enhancement by us.

Derivation - Treat Nulls as Zero

MikeMills

1

1 yearMikeMills (130): A new setting has been added that allows Nulls to be treated as zero within the derivation runtime: "Treat Nulls As Zero" https://forum.grovestreams.com/cached/dc1bd76f1453270f20dca3f274f7f09c.png Prior to this setting, many derivation expressions had to use the IsNull(..) function to handle nulls properly. This new setting simplifies expressions by avoiding the IsNull(..) call. If the dependent stream is a string, then...

problem with the example webhook and monnit

davidaguilar

8

1 yearMikeMills (130): Did you read the Troubleshooting part of the GS/Monnit tutorial? From the Troubleshooting section: "Ensure the iMonnit webhook is pushing data to GroveStreams by clicking the More button on the iMonnit webhook page. Click a transaction on the same page to determine if the transaction was successful or not." Do you see any transactions on this page? Are they successful?

1 yearMikeMills (130): Haven't gotten that many requests. Is this something you would use for your own use like monitoring your home or are you a business that would use if for thousands of homes? - that would give us incentive :)

Organization Backup and Restore

MikeMills

3

1 yearMikeMills (130): The size of the backup file is being added onto billing I/O. Some download sizes are approaching 1GB. We are reviewing the billing model around backups as the cost of doing a single backup can be cost prohibitive for customers.

Local timestamp (or age) of last sample

ctmorrison

2

1 yearMikeMills (130): We only return epoch millis. You're phone app programming language should have an api that allows you to convert/format it into your local time with the TimeZone of the user's phone. Yes, create a derived point stream (value type DATE) and derived from the source stream and set the value to one of these: SAMPLE_TIME: The time of the regular stream sample being calculated in epoch Milliseconds. SAMPLE_SDTIME: The start date time of the...

Time filter question

micromet

6

1 yearMikeMills (130): 401 usually indicates an authentication error. I wonder if your large string was assembled incorrectly and GS couldn't parse out the api_key. GS allows for very large strings. Was there an error inside your GS Organization System notifications? If so, can you post it? If not, then GS couldn't extract the api_key from the URL or the URL was corrupt. Email me the api_key and I'll search our logs to see if it even made it to our servers and if...

Calculate value at specific time of day

micl78

5

1 yearMikeMills (130): I just can't remember if the result will have a time of the beginning of the interval or the end of the interval. You still might want to use a DAY Interval stream for the derived stream.

Inactive Component Delete

phertel

2

1 yearMikeMills (130): You can delete an entire component folder manually. You can hold the Ctrl key and select multiple components and delete that at the same time. You can't configure GS to automatically delete components based on when their streams have been updated. But you can write code that interacts with the GroveStreams RESTful API to do what you want: www.grovestreams.com/developers/api_adv.html

Somewhat "missing" stream data

ctmorrison

2

1 yeartomMorrison (1): So...it's not really missing, as I perceived. It's just that it's showing very old (first post?) as opposed to data missing. When I look at the component, I'm seeing a "Last updated" for that stream of months ago. Yet, if I double-click on the stream, I see recent data. Very strange....

Locking map widget

ctmorrison

3

1 yeartomMorrison (1): OK. Perhaps that's the issue, but please consider this as a feature request on the backlog. I'm always signed in as an admin and the maps always get zoomed in/out and moved inadvertently. Thanks!

1 yearkinserc (1): Scott, I had the same problem. I found that my issue was because my browser had no access to 'ajax.googleapis.com'. I am a special case.. I live behind the Great Firewall of China (everything google is filtered). But maybe my problem gives you some insight to solve your problem. Check your 'hosts' file : C:WindowsSystem32driversetc
