I had a issue with my new (purchased last week) HP09 (Heat/Cool/Purifier) where it wouldn’t connect to WiFi on the Unit side (WiFi was animated indicating trying to resync) and in the app (showing not connected). It was showing connected on router side viewing router logs. No issues with WiFi even at the location of the unit (RSSI was 54dBm and download/upload speeds were 220Mbps/21Mbps at location of unit). The only thing that fixed the issue was deleting in app, resetting unit to factory and repairing. However, since adding back to the app ALL READINGS (Voc, PM2.5, PM10, No2 and HCHO) are 0. Prior to the rest there were times the PM2.5, PM10 and VOC were 0 and every once in a while increase to 1 or 2 so not unusual they are 0. And NO2 has only been 0. However the HCHO is 0.000 which is strange because the one week I had it it’s always been low but not all zeroes I think it was like 0.0010 on average. It’s almost like none of the readings are reporting since deleting and resetting everything. The Temp and Humidity are correct data. I hate that the unit is only a week old and having issues, not something I’m accustomed to with Dyson as I have had several other products for years with no issues.
