Sonos using 45 GB of bandwith in 24h

Question

I’ve recently installed my old Play5 (1st gen) in my summer house. The speaker was factory reset and then set up on my completely new home network (via WiFi). After using the speaker for a couple of hours, and again the following day (8-10h of music in total) I was surprised to see that it had used 45 GB bandwith! Checking my router it is clear that the Play5 uses around 195 mb every five minutes (external connection) - even when its not playing!  The network is through a brand new ASUS 4G-router with a SIM-card, providing a fine connection. The subscription only allows me to use 50 GB of bandwith per month. Only a Chromecast and the Play5 (along with my phone) is connected to the wifi. Sonos Support had never heard of this issue (odd?) and recommended that I turned off the speaker when not using it.Turning the speaker of every now and then sort of ruins the complete idea of having a remote controlled system? Several others have experienced this, but there is no answer how to avoid it?

Hi ​@Friis713Welcome to the Sonos Community!I am sorry to hear of this issue you have had with your Play:5 using up your data allowance.It is odd, and I don’t recall having heard of any such reports for a very long time, if at all.Please be aware that we do not support LTE (mobile/cellular) internet connections, but I do agree that this seems somewhat excessive.I have found your related support case and read the notes, and I can only agree with what was said - we will need to wait until you are with the speaker again before we can gather any data about what is going on.When you are there again, I have a couple of steps I’d like you to take before getting back in touch.We can only see the data usage in the diagnostics if you use an ethernet cable for connection, so please take one with you the next time you go to the summer house. Please connect the speaker to the router with the ethernet cablebeforeusing it at all. Once done, please submit a support diagnosticimmediately.Now, we don’t want to use up your data again, so please only test for 5 minutes, andafter doing so, please submit a diagnostic once more. Then, turn the speaker off so you don’t use up all the allowance.Please then get back in touchwith us, either here or through a call. If you post here, please only let me know you have submitted the diagnostics and I’ll find them - please don’t share the given numbers here.Hopefully, we will find some answers for you.
