Happy New Year to all of you! Here's how the year has started for Datacake.
✨ Widgets
☃️ Members and Organization
It is no longer possible to delete the organization admin from the workspace member list.
🌈 Zones

👮 Rule Engine Upgrades
You can set a product, device or tags filter in rules now
If no filter is selected, rules can be applied to the entire workspace (= all devices in the workspace)
Product + tags filter can be combined
If a rule has a device filter and all devices are removed from the workspace, the rule will be deactivated, so it is not executed for all devices in the workspace
If a rule has a product filter and the product is deleted, the rule will be deleted
The new measurement trigger will trigger by any new measurement by default for all new rules created
Before it would only trigger on new measurements that are referenced in conditions
You can specify selected fields on which the rule should trigger to keep the previous behaviour
Conditions are only available if you select a product filter or devices where all selected devices belong to the same product
Rule templates will pre-select the relevant trigger
New scheduled device-independent “system rules” can be used to schedule e-mail reports or downlinks

July 2023
5th July
Added new template language options to Rule Engine E-Mail and Webhook Editor
{{ <device>["location"] }}returns the device location{{ <device>["tags"] }}returns the device tagsFor SMS and email notifications, the new
joinfilter will be automatically appended when using the variable autocomplete feature.join(", ")will automatically separate all tags with a comma, but the separator argument can also be adjusted.For webhook notifications, the new
jsonfilter will be automatically appended when using the variable autocomplete feature, so the tag list can be send as valid JSON to another web service.{{ <device>["online"] }}returns the online status for the device, which is eitherTrueorFalseFor SMS and email notifications, the new
ifelsefilter will be appended when using the variable autocomplete feature.{{ <device>["online"] | ifelse("online", "offline") }}will convert the boolean value to theonlineorofflinetext, respectively.For webhook notifications, the new
jsonfilter will be automatically appended when using the variable autocomplete feature, so the online status can be send as valid JSONtrueorfalsevalue to another web service.{{ <device>["last_heard"] }}returns the online status for the device. Similarly to the measurement timestamps, the newdatetimefilter is automatically appended when using the variable autocomplete feature in the SMS or email editor.The new
ifelsefilter can also be used in combination with boolean measurement values. For example,The device is currently {{ triggering_device["measurements"]["IS_MOVING"] | ifelse("moving", "not moving") }}will convert boolean measurements into human-friendly messages such as “The device is currently moving” or “The device is currently not moving”.
4th July
Starting from July 4th, 2023, measurement timestamps are now supported in the Rule Engine notifications on the Datacake IoT platform.
This means that you can use the
{{ triggering_device["timestamps"]["TEMPERATURE"] }}code to display the timestamp of the measurement in UTC ISO format (e.g.2023-07-04 09:41:00+00:00).This is useful when the timestamp is sent through a webhook (by rule engine) and needs to be processed by a machine (which is receiving the webhook).
In addition, you can use the
datetime"filter" to render the timestamp in the rule's timezone, making it more human-friendly.By default,
{{ triggering_device["timestamps"]["TEMPERATURE"] | datetime }}will return the timestamp in the format2023-07-04 17:41:00.For more advanced formatting options, you can adjust the format using
{{ triggering_device["timestamps"]["TEMPERATURE"] | datetime("%A, %B %d, %Y %I:%M %p") }}(which returnsTuesday, July 04, 2023 05:41 PM).
Please note that when using the variable auto-suggestions feature, the webhook editor will insert the variable without the
datetimefilter, while the editors for emails and SMS will insert the variable with the datetime filter (but without a format argument).
