Getting updated reef-pi code from JFReyes

[Dewd]

I've just got round to updating to @JFReyes Modified Reef-pi, So I'm on 4.0 with the ability to specify chart ranges. It is fantastic! Very happy.

If I may suggest one or two mods to consider for the future........

1) The ability to specify the chart ranges in fractions. For example my pH - Only really needs to display 7.5 to 8.5, but I get the message that the range must me integer values, so I have set it to display 7 to 9. Not a big deal actually, but something to consider.

2) In 4.0, Ranjib did something to fix Adafruit IO integration. I used to constantly sit with 40+ errors in reef-pi, mostly relating to AIO. Updating to 4.0 fixed that. Updating to 4.0 MODIFIED sees those errors are back.

3) The 4.0 features of the Database export and updating through the UI are gone in 4.0 MODIFIED. Reef-pi reports that my version is 4.0-6-gbdd8708-MODIFIED, but a few of the 4.0 features aren't there, so is it technically still 3.XX where those features are concerned? I see other 4.0 features like the "Journal" tab (which doesn't work yet) are present.

4) Updating - In version 4.0, Ranjib added the feature to update reef-pi within the UI on the same page you can expo, and I see you have to put in the version you want to upgrade to (3.5, 4.0 etc etc) It would be really nice if you could drop the link to the update file in that box and have it update to whatever file you point it to.

Anyway, I'm really happy with the graphs, just throwing out where my head went with ideas and what I have seen.

Thanks for the great work.
