If you have power down in the cellar and your WiFi can reach that far why not use a picow connected to the dht22 and then mqtt to transfer messages wirelessly to the pi?
I've also had more success with the BME280 than the dht sensors. And they're 3.3v ready.
Bit of a learning curve but potentially worth it if you plan on adding more devices.
