Log
[homebridge-raspberrypi-info] This plugin generated a warning from the characteristic 'S2W2': SET handler returned write response value, though the characteristic doesn't support write response. See https://git.io/JtMGR for more info.

In the Eve app, everything still seems to work.

Same issue here. After updating to Homebridge v1.3.1 & v1.3.2

In Eve App Uptime/ Average Load is not shown

The warning are still there - also with Homebridge v1.3.2. But they disappear after several restarts of HB. And sometimes after another restart they come again.

In Eve App Uptime/ Average Load are shown.

After update of "homebridge-config-ui-x" to v4.40.0 today its starting again.

warnings no longer occurring after search & replace string "/uptime.txt" with "/tmp/uptime.txt" in file "/usr/local/lib/node_modules/homebridge-raspberrypi-info/index.js"

Found "uptime.txt" at 3 places. And all 3 are already set to "/tmp/uptime.txt".

So that doesn't seem to be the cause of the error.

It seems homebridge cannot write to /tmp.
To solve this:

1. check under which user-account your homebridge is running (it usually pi):
   ps -u | grep homebridge should return something like:
   pi 5379 0.0 0.0 4368 552 pts/1 S+ 10:11 0:00 grep --color=auto homebridge (username is indicated the in first part = pi)

2. find and replace whatever path is in /usr/lib/node_modules/homebridge-raspberrypi-info/index.jsto /home/<username>/uptime.txt. Replace <username> with the actual username from step 1, so for example /home/pi/uptime.txt

3. restart homebridge

Sorry @aebgit I don’t know why I loose sight of this issue. This was been solved at any point of time. And I don’t know with which version of HB, HB UI or HB Rasberrypi Info.

Yet no problems with:
HB: 1.5.0
HB UI: 4.50
HB Rasberrypi Info: 0.0.5

From my side this issue may be closed.
