A simple command-line python script to drive a robot vacuum. Currently
|
|
works only with the Ecovacs Deebot N79, as that's what I have.
|
|
|
|
This only covers my simple use case. There's a lot more it could do.
|
|
If you'd like to help flesh it out, send email to my first name at
|
|
williampietri.com.
|
|
|
|
If you're curious about the protocol, I have [a rough doc](protocol.md)
|
|
started. I'll happily accept pull requests for it.
|
|
|
|
Why the project name? Well, a) it's ridiculous that I needed to MITM
|
|
my own vacuum. This is not the future I signed up for. There should
|
|
be a nice, tidy RESTful API. That would be easy enough to make. And b),
|
|
it's a vacuum.
|
|
|
|
## Usage
|
|
|
|
To get started, you'll need to have already set up an EcoVacs account
|
|
using your smartphone. I've only tested this with Android, but I expect
|
|
it will work with iPhone-created accounts as well.
|
|
|
|
Step one is to log in:
|
|
```
|
|
% sucks login
|
|
Ecovacs app email: [your email]
|
|
Ecovacs app password: [your password]
|
|
Config saved.
|
|
```
|
|
|
|
That creates a config file in ~/.config.sucks.conf. The password is
|
|
hashed before saving, so it's reasonably safe.
|
|
|
|
With that set up, you could have it clean in auto mode for 10 minutes
|
|
and return to its charger:
|
|
|
|
```
|
|
% sucks clean 10
|
|
```
|
|
|
|
You could have it clean for 15 minutes and then do an extra 10 minutes
|
|
of edging:
|
|
|
|
```
|
|
% sucks clean 15 edge 10
|
|
```
|
|
|
|
If you wanted it to clean for 5 minutes and then stop where it was,
|
|
either of these would work:
|
|
|
|
```
|
|
% sucks clean 5 stop
|
|
% sucks --no-charge clean 5
|
|
```
|
|
|
|
If it's running amok and you'd just like it to stop where it is:
|
|
|
|
```
|
|
% sucks stop
|
|
```
|
|
|
|
To tell it to go plug in:
|
|
|
|
```
|
|
% sucks charge
|
|
```
|
|
|
|
I run mine from my crontab, but I didn't want it to clean every day,
|
|
so it also has a mode where it randomly decide to run or not based on
|
|
a frequency you give it. My crontab entry looks like this:
|
|
|
|
```
|
|
0 10 * * * /home/william/projects/sucks/sucks clean -f 4/7 15 edge -f 1/14 10
|
|
```
|
|
|
|
This means that every day at 10 am, it might do something. 4 days out
|
|
of 7, it will do 15 minutes of automatic cleaning. 1 day out of 14,
|
|
it will do another 10 minutes of edging. And afterward it will always
|
|
go back to charge.
