The problem
Its summer here, so higher temps & I noticed solar Inverter was quite hot one day so I checked the temperature sensor from Solax inverter integration - it was fine real time (40C) but on looking then at history I see these apparently random (x7 this month) sudden drops in temperature history to -9,824C at around (but not exactly the same time) 5:50AM. (I determine this by clicking on the HA history graph to see temp value and time.) Last month I see seven too, however temp then dropped to between -57C and -249C. These drops occur all the way back till I installed integration August 2023 I now see. I've attached screenshots which hopefully is sufficient to show the description of the issue. Other observation is the drops to the -9000 range have started from around November this year - again visual indication from Inverter temperature history graphs. The effect is temperature monitoring by visual graph is now being effectively masked by these massive temp drop spikes - resulting in the graph scale self adjusting to display these & 'otherwise 'normal temp readings are drowned and appear all as a straight line (because their variations are so small compared to these spikes). happy to provided as anything else needed. Is anybody else seeing this? would it be possible to look at correcting (or filtering out any significant negative values) in the sensor? Thanks
