Raspi-sump is a sump pit water level monitoring system using a Raspberry Pi and an Ultrasonic Sensor (HC-SR04)

Currently the system monitors the water level in your pit at defined intervals. It sends email sms alerts if the water reaches a critical level, indicating a possible sump pump failure.

See the changelog for changes to all versions.

You will need to add variables to your raspisump.conf file. Copy the new conf file located in the /home/pi/raspi-sump/conf folder to /home/pi/raspi-sump. Re-enter all of your variables. Older info has been saved in /home/pi/raspi-sump/raspisump.conf.save

Simply upgrading from version 0.5.x will break your current install of Raspi-Sump unless you take some time to fix your configuration file.

I recommend you keep using v0.5.3 if you don't want to do this.

To roll back to v0.5.3 simply do the following;

sudo pip uninstall raspisump
sudo pip install https://pypi.python.org/packages/source/r/raspisump/raspisump-0.5.3.tar.gz#md5=91aed30a087c35e12ae36fe7a9523945

If you are running version 0.6.0 or later you need not change anything.

Install the pip package manager (if not present on your pi).

sudo apt-get install python-pip

Install Raspi-Sump.

sudo pip install raspisump

Upgrading an existing version

sudo pip install -U raspisump

This will also install the HCSR04sensor and RPi.GPIO modules if not present on your Pi.

If you want to use charts install maplotlib and numpy

sudo apt-get install python-matplotlib

sudo apt-get install python-numpy

Read the configuration docs copied during setup on your pi at the following location;

You are welcome to use Raspi-Sump but there is no guarantee it will work. Your house may still flood if your sump pump fails. This software comes with no warranty. See License details.

This is not a replacement for remaining vigilant in maintaining your water pumping system. It is one tool you can use to give yourself extra piece-of-mind.

Best practices should also include:

• A backup pump that triggers at a slightly higher water level than your main pump.
• The secondary pump should be connected to a seperate dedicated electrical breaker.
• You should also have a generator that can provide power should you have an extended outage during the spring or other unseasonally wet time of year.
• if you are building a new home, pay attention to the grade of your property, as you may even be able to let gravity empty your pit for you. That would be the best approach with a backup pump just in case.

Once you have done all of these things, then consider using a monitoring system like Raspi-Sump.
