I’ve been running the default setup SDS011+BME280 for awhile now and the BME280 is pretty accurate but the PM10 of the SDS011 is sometimes way off. Because of this and the comment that the SPS30 is more accurate I bought a SPS30 and created a second node with SHT35 and SPS30. The SHT35 is way off (could be the casing) and SPS30 shows a lot of times the same values for PM1 to PM10 while it’s almost sitting outside the cage. The same issue for SPS30 is described in SPS30 PM10 no difference to PM2.5 · Issue #673 · opendata-stuttgart/sensors-software · GitHub
