Elsys ERS sensor issues

Hello All,

I have an Elsys ERS sensor. Based on some other posts I see people have these working on ChirpStack, but I am having issues. I can get the ERS to eventually join the network. It will send an UPLINK request and the server responds with a DOWNLINK LinkADRReq. The ERS never seems to respond to this or respect it. I say this because the ERS sensor will send a few UPLINK messages and then fails to check in for hours. As if its switching to a channel Chirp Stack is not using. I have it set to check in every 10 minutes right now while I am testing it.

Any recommendations or any with experience with these sensors? I’ve tried contacting Elsys directly, but I am not getting responses from them.

Thank you,
Kevin Runde
