WN34 Support Changes
The Ecowitt LAN/Wi-Fi Gateway API documentation v1.5.9 included support for the WH34 temperature sensor. Consequently, support for the WH34 temperature sensor was included in the then GW1000 driver v0.2.0 with WH34 temperature data for up to eight sensors mapped to WeeWX fields extraTemp9 to extraTemp16 inclusive. Ecowitt subsequently released soil and liquid temperature sensors, designated WN34S and WN34L respectively, that use the same sensor addresses as the previously documented WH34 temperature sensor.
Temperature Data. The Ecowitt gateway driver v0.5.0 changed all references to WH34 to WN34. This change is an internal change only as the WN34 temperature data is presented on internal fields temp9 to temp16 inclusive that are default mapped to WeeWX fields extraTemp9 to extraTemp16 inclusive.
Note: The Ecowitt LAN/Wi-Fi Gateway API does not provide the means to discriminate between soil temperature sensors (WN34S) and liquid temperature sensors (WN34L). Consequently, the default field map used by the Ecowitt gateway driver maps WN34 temperature data to WeeWX fields extraTemp9 to extraTemp16 inclusive. Users who wish to have WN34 temperature data appear in other WeeWX fields (eg, having WN34S temperature data appear in WeeWX field soiltemp1) will need to implement a custom field map.
Battery and Signal State Data. Earlier versions of the Ecowitt gateway driver did not provide WH34/WN34 battery and signal state data. As of v0.5.0 WN34 battery and signal data is mapped to WeeWX fields wn34_chx_batt and wn34_chx_sig where x is the WN34 channel number on the gateway device being used.
Running the Driver Directly. WN34 users will notice a slight change in the console output of some options when running the driver directly. Users will notice that the output now correctly refers to WN34 sensors rather than the previous WH34.
Users with WN34 sensors who upgrade from v0.4.2 or earlier need take no action. WN34 temperature data mapping will be unchanged after upgrade to v0.5.0.
WN34 users who wish to utilise the WN34 battery and signal state data can access this data via WeeWX fields wn34_chx_batt and wn34_chx_sig where x is the WN34 channel number on the gateway device being used. Users may map these fields to another WeeWX field via a custom field map.
