Compatibility Instructions
for all ecowitt network consoles
Please refer to the table to choose the correct sensors and consoles before checkout.
Note:
1) "1/4/8/16" = max number of sensors supported per console (excluding accessories).
2) Upload only = sensor readings shown only in the Ecowitt app and cloud (www.ecowitt.net).
3) Firmware (e.g. V1.9.6 / V2.0.2) = gateway/console must run this version or newer.
