Will the wifi version of the sensor work with slow wifi?

Hi @lizg.nm, you can view the data usage of PurpleAir sensors in the following article: PurpleAir Sensors Functional Overview. PurpleAir sensors send minimal data, so it should still work even with a slow WiFi connection. Ensure that the device is close enough to the router that it won’t disconnect, and make sure that not too many devices are connected to the network, causing it to slow down too much.
