I have appended my problem to the thread so the initial issue is not the resolution. Have you read the whole thread?
My issue was introduced in 2.2.9.xxx and I'd be surprised if yours wasn't too. But I don't know of course.
Can I ask if your are using hub mesh with security enabled?
Yes using Hub Mesh and no security enabled ran into too many issues with Security enabled.
LTS is still failing on some devices but not on others.
I just had a lightbulb moment.
I share zwave devices from Heating Hub to Master Hub using Mesh.
The graphing is all done on Master.
I had turned up the logging on devices on the Heating Hub and just noticed the events are stored and controlled locally so turned up logging on Master and the graphing is working again - albeit without LTS.
So a workaround.
I do hope the good folks at HE find an alternate easy to use graphing solution.
Nudging this old thread back to life. I'm experiencing something similar. I have two new Zigbee Sensors that definitely are producing data. I can see the values changing "live" and I send those values to Home Assistant via the Maker API. I can see graphs there. But Long Term Storage doesn't seem to be capturing the values at all. I have other sensors for which Long Term Storage is working perfectly. Any clues as to what might be happening? I am using sensors from ThirdReality. They use the standard ZigBee Generic Temperature + Humidity sensor driver.
Is it a case that the sensors are new in your setup and not working after you set them up with LTS, or they were previously working and a recent platform update or something similar has made them stop working?
These are new sensors in my system. I have been using LTS for a long time without issue with similar sensors that use the same driver. But these are new and seemed to be liked by others in the community.
