Subject: [PATCH] Add relevant OR part as well

The relevant "OR echo '{"batteryVoltage":3340,"battery":99}'" is still missing. So the script still crashes NightScout in its current state.
Now added that line and the explaining line of comment as well. Tested for several days on Pi & RadioFruit Bonnet combo with two different NS instances.
