Venus OS Large 2.80-26 Node-red problem, value becomes array

I have a problem with the latest and a few versions ahead of venus-os large 2.80-Large-26.

This applies to node-red and reading of temperature data. Everything worked well before, but now the readings from the web page freeze after about 10 seconds, that is when input data changes value from normal value to array value

39.7

com.victronenergy.temperature.Rpi_cpu_id06 - / Temperature: msg.payload: number

to

com.victronenergy.temperature.Rpi_cpu_id06 - / Temperature: msg.payload: array [1]

[39.7]


Tried to troubleshoot but could not find the problem

Same problem with CpuTemp and RuuviTag

Hi, @mvader (Victron Energy)

Tested v2.82_5-large-27 now. on pi 2, pi 3 b + with original image and pi4 with updated kernel. Temperature data seems to work well.

The only thing is these error messages that I get in message log, and is the same on all pi's normal, large and modified kernel. about 10kB per hour

EDIT

Figured it out. This is when ruuvitags are switched on (2 pcs.)

Have scanned for bluethoot devices, but there are only these two

4577 and 7A5E. and the nearest house is 100m away There are more in the list than the picture shows, and it is growing all the time
