Hello, I had the Dragino DG-LHT65N-868-E3 temperature/humidity sensor actively integrated into my home automation system for about a year, and the sensor worked well and correctly displayed three entities (indoor temperature, outdoor temperature, and humidity). It still does so via the Datacake application. I use message storage and payload formatters (JavaScript). Now, only bytes are displayed in the live data. Previously, I also saw the indoor and outdoor temperatures and humidity levels here. Why are only bytes displayed now? Can anyone help?
If Datacake still decodes the values correctly, the issue is probably not the sensor itself. I’d check whether the JavaScript payload formatter is still assigned properly, because there may not be a simple fix if live data is only showing raw bytes.
Are you able to see from historic data when the change happened for the 1st time - then correlate to any s/w updates or revisions etc. (e.g. a recent TTS stack or some such update, updates to your underlying HA system, etc.), power outages affecting your home (potential corruption source) and so on. (Know original post is old and OP hasnt updated on solution, but as now live again posting this as pointers to anyone experiencing similar issues and needing hints for debug
