Hello,
I recently bought the DIY version of the Model: I-9PSL-DE-CE indoor AG monitor. It went live on Nov 14 2025 and worked perfectly until this morning when it displayed an unusual LED pattern : The extreme left LED is violet (and should be off) and the extreme right LED green (correct PM2.5 value). I performed a LED test, but it the problem persists. Any ideas how to further troubleshoot ?
