I’ve been working on an integration between SmartThings and https://www.constantgraph.com (which is a cloud based logging and graphing site for home automation). ConstantGraph has been working with the Ezlo/Vera platform for a while now but this is the first attempt to hook it up to SmartThings. I…

I recently found out that Personal Access Tokens (PATs) created after 30 December 2024 now only last for 24 hours (see Authorization and Permissions | Developer Documentation | SmartThings ) which is a quite a bit less than the 50 years they used to last for.

I’d just like to announce that the latest release of ConstantGraph now includes the ability to completely resize the channel list on the left and also adds last update date to the list of columns that can be selected and sorted in the list. This should help people find and select their channels for…

I would like to suggest that the Timezone and the Location (for time bands) should be set per location and not for the account. I have four locations across 3 time zones and 2 continents so my data is not being aggregated correctly. thanks in advance

Could …
