python-miramode

Python module for controlling Mira Mode digital showers via BLE.

Mira Mode is a line of digital showers and bathfills from Mira Showers. They work great in my experience, but having only a Bluetooth Low Energy (BLE) interface, they can only be controlled locally via smartphone and not via Alexa, Google Home and the likes, which makes the whole experience significantly less useful.

Alexa, turn on the shower!

To overcome this limitation, here's a Python library that can be used to control Mira Mode devices from a Raspberry PI or any other computer equipped with BLE capabilities, allowing an easy integration with projects like Home Assistant which can then expose the shower outlets as switches to Alexa or Google Home.

This project contains a CLI utility to perform operations on the shower and a Python library that can be used by other projects.

Requirements

1. Python 3.9 and above
2. A Bluetooth Low Energy (BLE) interface, already included in Raspberry Pi devices, MacBooks and most laptops
3. On Linux, make sure the bluez package is installed
4. Install this project:

cd python-miramode

# Optionally use a Python virtual environment:
python3 -m venv venv
. venv/bin/activate

pip install .

CLI Examples

First, obtain the address of your shower device. Look for devices with a name starting with Mira:

miramodecli devices-list

The device address has the "xx:xx:xx:xx:xx:xx" format on Linux and Windows, and a UUID format on MacOS.

For additional CLI usage help, just run miramodecli without arguments or with a command followed by -h, e.g.:

miramodecli outlets-control -h

Pair a new client

The -c argument is used to pass the new client id. If not provided, a random id will be generated. Take note of both the client id and the client slot returned by the device, as those will be needed when sending other commands. Do not forget to put the device in pairing mode by pressing the shower outlet button for 5 seconds!

miramodecli client-pair -a <address> -c <new_client_id>  -n <new_client_name>

List existing clients:

The following command will list the existing clients, please note that it requires a valid client id and its corresponding slot, obtained from a previous pairing:

client-list -a <address> -c <client_id> -s <client_slot>

Unpair an existing client

miramodecli client-unpair -a <address> -c <client_id> -s <client_slot> \
-u <client_id_to_unpair>

Turn the outlets on or off

miramodecli outlets-control -a <address> -c <client_id> -s <client_slot> \
-o1 <on|off> -o2 <on|off> -t <temperature>

Start a preset

This is useful for e.g. starting the bathtub fill.

miramodecli preset-start -a <address> -c <client_id> -s <client_slot> \
-p <preset_slot>

Use the outlets-control command to turn off the outlet(s) before the preset's timer ends if needed.

Set debug logging level

For additional logging details, all commands support a --debug argument, e.g:

miramodecli client-pair -a xx:xx:xx:xx:xx:xx -c 100100  -n Foobar --debug
