Receive MQTT Message

[PhotonHebs]

Thank you for writing this byte4geek! It will be unbelievably useful... amazeballs!

I have got to the stage where I test the communication ~/SEPLOS_MQTT/query_seplos_ha.sh 4201 and all is well - all of the measurements are displayed in my terminal window.

However, I have been unable to receive the MQTT message. I have triple checked my broker details and they are correct. I am running mosquito on another raspberry pi and it definitely works well because it is throwing around hundreds of messages between various pis running node red.

I run ~/SEPLOS_MQTT/run_bms_query.sh & nohup ~/SEPLOS_MQTT/run_bms_query.sh & but nothing happens. I ran sudo ~/SEPLOS_MQTT/run_bms_query.sh and it displays the following on the terminal:

Try 'sleep --help' for more information.

Is this a permissions thing? I note the response above mentions /root/SEPLOS_MQTT/... is that correct?

Any help would be very much appreciated, thank you.

Update, I received one message randomly so I know that I have the topic right, however, the cron or manual triggers don't seem to result in another message being sent.

what is the path where did you install the script? what is the user you used?

for example if you install under /home/pi with user pi do not run it wiht sudo, because sudo run it as root env and try to use /root folder, if you installed the script using sudo it is possible you have right permission of the file wrong that user pi can't access.

Hi @byte4geek , I had the same issue and your proposed solution worked for me. Simply git cloned without using sudo and now it works. Thanks!
