Problem solved, seemed I got one sensor on bus damaged on data wire and this caused this problem. Best Jiri.

1Wire multiple sensors
I am new to Unipi 1.1 and EVOK. I got several temp sensors (DS18B20) across my house which are connected in serial. I am using RJ45 splitter for each room and from last position it is connected to 1Wire on UniPi.
The main problem is when I run EVOK, it will found all sensors but only for 7 sensors temp is shown. Others are N/A... It will throw me an error:
Traceback (most recent call last):
File "/usr/lib/python2.7/multiprocessing/process.py", line 267, in _bootstrap
File "/opt/evok/owclient.py", line 395, in run
File "/opt/evok/owclient.py", line 126, in read_val_from_sens
if not (new_val == 85.0 and abs(new_val - self.value) > 2):
TypeError: unsupported operand type(s) for -: 'float' and 'NoneType'
Anybody occure same problem? What is the best approach to have multiple sensors on 1Wire?
Thanks for replay. Jiri.
Remote controll of EVOK API
Is there any solution how to remote controll UniPi API requests? For example from my phone outside local network.
I think about public IP address with forwarding to Raspberry, but this can be potentional threat, if there is no authentication on EVOK API (maybe i am out of date).
Thanks for reply
