Robo-Tank v6.0 is Ready - Now v6.5

[pwest]

Thanks for this.  I followed the instructions, and now the ph probe 'box' and graph on the dashboard are gone as desired.
The new 'Room Temp' probe has appeared, BUT, it seems to have replaced the original 'Tank Temp' box,  added a new graph, and the original Tank Temp graph is no longer updating.

One question.  You said to comment out the first dtoverlay=w1-gpio line. That line appears multiple times and I only removed the first occurance.  Should the other be removed as well.  Here's a snippet from the file:

# Uncomment some or all of these to enable the optional hardware interfaces
dtparam=i2c_arm=on
#dtparam=i2s=on
#dtparam=spi=off
dtparam=i2c_arm_baudrate=10000
#dtoverlay=w1-gpio
dtoverlay=w1-gpio,gpiopin=4
dtoverlay=w1-gpio,gpiopin=17
dtoverlay=pwm-2chan
dtparam=i2c_arm_baudrate=10000
dtoverlay=w1-gpio
dtoverlay=pwm-2chan
dtoverlay=w1-gpio
dtoverlay=pwm-2chan
dtoverlay=pwm-2chan

I restarted a couple of times but saw no changes.

Thanks,
Phil
