The sensor is located where the red arrow points. It looks like there is enough coverage there but the sensors won’t connect (or at least won’t appear as connected in our application).

Gateway details:  
**Name** RAK2245-RPi  
**ID** rak2245-rpi  
**EUI** B827EBFFFE9E871E  
**Network** NS\_TTS\_V3://ttn@000013  
**Description** Uncannier Software RAK2245 RPi3B+ 915MHz

**Last heard** Tue, Dec 12, 2023 10:34 AM CET  
**Lat, Lon** -31.9931, 115.80183  
**Altitude** 32m

The sensors work on AS923 frequency. They are Sensoterra sensors ( [Product - Sensoterra](https://www.sensoterra.com/product/#single-depth-sensor) )

Any help will be appreciated

there are two different channel planes in aus

AU\_915\_928 and AS\_923

```auto
{"netID":"000013","tenantID":"ttn","id":"rak2245-rpi","eui":"B827EBFFFE9E871E","clusterID":"au1.cloud.thethings.network","updatedAt":"2023-12-12T10:05:26.922718Z","location":{"latitude":-31.9931,"longitude":115.80183,"altitude":32,"accuracy":0},"antennaPlacement":"OUTDOOR","antennaCount":1,"online":true,"frequencyPlan":{"region":"AU_915_928","loraMultiSFChannels":[916800000,917000000,917200000,917400000,917600000,917800000,918000000,918200000]},"rxRate":0,"txRate":0}

```

that gateway is on AU\_915\_928 and your sensor is on AS923

you will need to most probably get your own gateway

as the closes one to you is some 6km away
