Please have a look to the column containing the indoor temperature, it should be around 27C, but sporadicly 40C or -9C occur.

I can also provide a log file (around 500kB) where other fields are effected.

HW setup: WS2350 with outdoor unit connected by radio, 20m RS232 cables (telephone extension), RS232 to USB (was delivered with the WS)

SW setup: NSLU2 running with debian lenny, 2.6.26-2-ixp4xx, no modifications, open 2300 compiled without error messages, all 2300 bins are working without error output (using also fetch2300)

Maybe you can have a look into that.

Thanks
