Have you thought about adding the Sen55 (PM + temp, hum,…) type to the opensensemap database? We have 35 PM boxes with SEN55 (now the SC firmware converts it to SPS30 type) which is NOT correct. And we have 5 PM boxes with 2 PM devices (SDS11 and SEN55), we can do it on the convert way but it would be nice if we could enter this correctly in opensensemap.
Hello! Great input, thank you! 
I have created a ticket here and we will keep you updated on its progress: support SEN55 sensor for Sensor.Community devices · Issue #1070 · openSenseMap/frontend · GitHub
Just to make sure: Your are referring to this sensor model, right? SEN55 - Environmental sensor node for PM, RH/T, VOC, NOx measurements
That’s right, we are talking about this model.: SEN55 - Environmental sensor node for PM, RH/T, VOC, NOx measurements
