crypto_lamp

A python script for smart lightbulbs that shows how badly you're losing money in crypto. Glows green when you're up, red when you're down.

You will need:

Phillips Hue Color Bulb + a Hue Bridge
The Blockfolio app (free, iOS/Android)
A lamp
A computer capable of running Python. A raspberry pi would work fine

Setup

Lightbulb setup

Set up your Hue bridge + bulb. Make sure it's plugged in
Find the IP of your Hue bridge and add it to the crypto_lamp.config file under hue_bridge_ip
Go to http://<bridge ip address>/debug/clip.html
Follow the instructions here to obtain a user token to use the Hue API. Add it to crypto_lamp.config under hue_user_token
In that same Getting Started page on the Hue website, follow the instructions to obtain the ID for the lightbulb (a GET request to http://<bridge ip address>/api/<user_token>/lights). Add the lightbulb ID (should be a number) to crypto_lamp.config under hue_light_id

Blockfolio setup

Download the Blockfolio app
Update your portfolio
Go to settings and find your user token at the bottom of the screen. Copy it and add it to crypto_lamp.config under blockfolio_token

Running the script

You will need a computer capable of running Python. You can download python on any OS (a lot of OSes come packaged with it).

There are two modes you can run. One uses the 24hr percent change on your Blockfolio portfolio (number at the top right), and the other calculates the delta between each time your run the script. If you run the delta mode, the first time your run the script will always show green since it will treat your previous balance as $0.

To run the script, navigate to the root folder of this project in your terminal and enter python am_i_broke.py. This will run the script in 24hr percent change mode. To run it in delta mode do python am_i_broke.py --delta instead. In delta mode, the previous balance is stored in a crypto_delta.dat file. If you modify this file the script may not run properly.

Scheduling

If you are running the script from a Linux device or Mac, use cron to schedule the script. Not sure the best way on Windows, but I'm sure there's plenty

Adjust parameters

There are a few parameters in the script you can tweak. Edit am_i_broke.py to change them.

SATURATION - By default I left it at 254 (max). you can lower it if you want a more white hue of green/red
GAINS_MAX - What percent gains should make the light shine brightest. It will increase from brightness from 0% to whatever this value is. If it goes pass this value it will start flashing. You should tweak this based on how often you are running the script. For example if you are running it daily, 20% may be a good max number for gains, but if you are running it every 5 minutes, it could be as low as a few percents.
LOSS_MAX - Same as above, but for losses. This one is negative
GREEN_HUE - The type of green used when you're up. This can be changed to any color. see the Phillips Hue documentation for other color values
RED_HUE - same as above. This is the hue used when you're down

Troubleshooting

Make sure the values in the config file do not have any whitespace between the =. This will cause them to be parsed incorrectly

The first time you run this script in delta mode, or if you have deleted the generated crypto_delta.dat file, the lamp will always be green on the first run. This is because without the file it treats your balance at $0. Subsequent runs will be correct.

Do not modify the crypto_delta.dat file. This could cause the script to crash. If you suspect that file has become corrupted, just delete it and run the script again.

Brightness is based on your GAINS_MAX and LOSS_MAX values. Adjust these params based on how often you run the script, and how much money expect to lose or make. Any gains or losses over these will trigger maximum brightness plus an annoying flashing effect. If you want to disable the flash, change the ALERT_MULTI_BLINK variable in the script to "none".
