Cannot read data from my sensors

[hesspoint]

Hi, I installed plantgateway on a Pi Zero. Then I run plantgateway it seems to work and everything is updated. Home Assistant shows all data. Perfekt. I setup a cronjob to run plantgateway every hour so that HA gets an update once per hour.

However when I look in HA it show the initial data and then nothing. Last update 15h ago or so.

I looked into the logs and for all 3 sensors in the room I get an exception. Actually it says “connection accepted” but then it cannot read data. The strange thing is that it was working at the beginning and I did not change anything after that except setting up the cronjob. Even when I run plantgateway manually now again it also throws the error “Cannot read data from....”

Here is an excerpt from the log (I replaced the real MAC address with XX:XX:XX:XX:XX). It is a bit beyond my skills to make sense of that but hopefully some of you can.

Sun, 15 Nov 2020 01:04:20 INFO MQTT connection returned result: Connection Accepted. Sun, 15 Nov 2020 01:04:21 INFO MQTT connection returned result: Connection Accepted.

The above exception was the direct cause of the following exception:

Thanks very much for your help!

Hi, It has been 17 days and no answer. It would be great to get a quick feedback if I can solve this somehow or what I am doing wrong. Thanks :)

This is an open source project. there are no guarantees whatsoever. Also not on responding to issues.

From the logs I guess you Pi can't connect to the sensor. This could be for any reason two bluetooth devices can't connect. So I can't tell you how to fix this.
