February 07, 2023, GP2Y10+MiCS6814, cleaned + BME280 replaced, restarted at location. December 22, 2022, SDS011+BME280 cleaned & restarted at location. December 15, 2022, BME280 for SDS011 replaced => setup testing indoors. December 14, 2022, SDS011 cleaned, tested & revived. Related BME280 defect. December 13, 2022, SPS030+SHT31 testing (1 week). December 07, 2022, GP2Y10-setup: MiCS6814&BM280 readout restarted June 16, 2022, GP2Y10-setup: MiCS6814&BME280 break down; requires rebuild of cluster March 06, 2022, SDS011 breaks down; at least requires restart/reflash of the NMCU => temporary flatlines for all SDS-related info September 14, 2021, SDS011 restarted outdoors. May 25, 2021, THB related to SDS011 also breaks down; at least requires restart/reflash of the NMCU => temporary flatlines for all SDS-related info May 04, 2021, THB related to GP2Y10 breaks down; May 08 basically corrected, but defect of barometer requires systemwide change of related software [eliminating/replacing this pressure-info] December 28, 2020, SDS011 starting 18:00 again in modified setup [adapted housing & airFlow] December 02, 2020, SDS011 out due to shortcut in power-interface (due to flooding) July 23 ~ 30, 2020, No registration & webdisplay for Dust & Gas due to breakdown of Domoticz2 April 29 ~ May 05, 2020, WLAN-breakdown handicaps the measurements with GP2Y10+MiCS6814 February 07, 2020, 230V-dip requires power reset for Sensorsetup with SDS011 January 8~9, 2020, the Sensorsetup with SDS011 requires reflash due to power cut-off December 3~5, 2019, the Sensorsetup with SDS011 is stuck due to drowned DHT22 T&H-sensor: => reflash required The constant values in that period for PM2.5/PM10 + BME280/DHT22 are 'leftover's and the variable values are experimental from indoor testing after drying & modification. - Remarkable observations [most recent at top!]: # April 18~24 2020, Extreme level of poll according to GP2Y10 SDS011 'normal' # December 31, 2019 ~ January 1, 2020, 00:30 = New Year's Fireworks in cold, thick fog # June 26, 2019 = Fire at Twence Hengelo # June 03, 2019 = Paint job at neighbour's house (but that does not explain the GP2Y10-peaks in the night) # May 26, 2019 = Fire at Twence Hengelo # March, 22~23, 2019 = Hayfewertime due to blossoms/flowers? # March, 02, 2019, 13:30~14:30 = openair spraypainting3 meteo-covers, mild SW-wind, at 20m distance! # March, 02, 2019, 10:30 = cleaning of path under the sensors with hydrojet [unexpectedly visible!] # February, 26, 2019, 15:00 = openair spraypainting2 meteo-covers, no wind, at 25m distance! # February, 25, 2019, 17:00 = openair spraypainting1 meteo-covers, no wind, at 25m distance! # January 05, 2019, 18:00 = bonfire - Christmas' trees # December 31, 2018 ~ January 1, 2019, 00:30 = New Year's Fireworks # June 30th ~ July 01st, 2018 = Fire at Twence Hengelo # April09, 2018 = Sahara-dust?

Explanation for peaks/jumps/dips in the longterm-graphs: # March 26 till April 03 experiments with rules for ESPEasy. # 'Spike' at April 03, 10:30 is result of experiment with filters & rules after change of GPIO-setting # experiments with ESPEasy-rules till 6th of April: latest rule is (%value - 1000)*0.05 # April 14th, 03:00: unrealistic high rise in dustvalue. 10:00, Restart & back to 'Experimental' with unchanged rule. # April 18th, 15:00: new empirical rule = (%value - 1200)*0.025 # Since week 27 dustvalues >300 # July 20th, 16:30: new empirical rule = (%value - 15000)/40 # July 26th, 12:00, Measurement totally false with value -221 Try&error: new empirical rule for GP2Y10 = (%value% - 5000)/40 # July 27th, 12:00, Measurement again <0 [-30].
