Async library to interface with Gecko Alliance spa pack systems via in.touch2
Written from the ground up using info gleaned from Wireshark captures to sniff the conversation between the iOS app and the inTouch2 home transmitter.
Designed to be used by home automation systems such as Home Assistant or openHAB
This library is now Beta, meaning that there are unlikely to be major changes in library shape, class definitions, behaviours etc as I client it in my ongoing Home Assistant integration. This has now been released, in preview, and can be found at https://github.com/gazoodle/gecko-home-assistant, or from HACS by adding a new integration and seaching for Gecko
This library is hosted on PyPI and can be installed with the following command-line
pip install geckolib
Once the library is installed, you should be able to start a Python interpreter session
by using the command python3, then executing the following commands
>>> from geckolib import GeckoShell
>>> GeckoShell.run()

If you want to get some diagnostics you can enable file logging at the start of the session
>>> from geckolib import GeckoShell
>>> GeckoShell.run(["logfile client.log"])
:
:or it can be used later after you've connected to your spa with the logfile command
Spa$ logfile client.log
The file client.log will contain diagnostic information that may be useful
for tracking down issues
If you want to start the client and point it at a specific IP address (maybe you have your SPA on a different subnet), you can issue the discovery command as part of the launch parameters
>>> from geckolib import GeckoShell
>>> GeckoShell.run(["logfile client.log", "discover 192.168.1.2"])

:It's best if you download the repo for using the simulator. Once you've done that, open a terminal to your repo test folder (./tests)
python3 simulator.py
You should see a prompt
Welcome to the Gecko simulator. Type help or ? to list commands.
(GeckoSim)
You should load the default snapshot at this point
(GeckoSim) load snapshots/default.snapshot
(GeckoSim)
Now you can run the client program, or indeed your iOS or Android app and then attempt to connect to the simulator. At present it only supports loading another snapshot to change the state. If the changes are too great, for example, if you've loaded a completly different spa then the iOS and Android apps may be confused.
Best to click on the account icon and then reselect the test spa to get it to reconnect from the start.
Also, at present the simulator doesn't respond to any commands issued from the iOS and Android applications.

- Inspired by https://github.com/chicago6061/in.touch2.
- Thanks to the folk at Gecko for building this system as a local device rather than mandating a cloud solution.
- Wireshark is an awesome tool for sniffing out what is going on on your network. Take a look one day, you might be horrified :-)

- Error handling (ongoing)
- Pythonize where possible
- More unit tests
- Handle other device types such as Waterfall
- Handle inMix for lighting control
- Add API documentation
- Tidy up support files. One class per file
- Full sweep for typing hints - Ongoing
- Add switch for winterizing
- Add ability to set hours so we can implement a crude clock sync mechanism
- Move to pytest unit test framework (replace all unittest fixtures and custom asserts)
- Use snapshots to generate some specific tests
- Build some documentation
- Add coverage to GitHub package workflow
- API set_config_mode needs to be per device rather than global
- Need to develop a way to force reconnection if certain accessors change, the intouch2 application will do this if certain values are changed, and using the simulator snapshots, I've noticed that the HA integration can get confused leading to possible values beiing posted to the wrong locations.
- Move localizable strings so that HA can handle itself
- Add command to simulator to start a blank configuration instead of loading a snapshot
- Use MinSetpointG and MaxSetpointG if available
- One of the accessors is AuxAsBubbleGen. Investigate how this is used
- Add a watt setting to pumps, heaters and so on so that the library can produce an instantaneous power consumption figure which ought to be able to integrate into HA's energy dashboard.
- Add ability to change the RF channel. The app sends a CHACH\xb4\x0c command, play in the simulator!
- Add support for lock mode if it exists on the spa
- Add support for standby mode
- Add "Heating" binary sensor
- Breaking change, removed all sync APIs
- Require Python 3.13 as minimum version
- Made unit tests pass after sync API removal
- Refactor a bit of the protocol stack to DRY out some code
- Added "Spa In Use" sensor
- Added useful diagnostic functionality to shell and simulator
- Added support for external heat sources
- Remove deprecated constant, it's only available in Python 3.13 from warnings, we can re-add it adter this package is released.
- Min Python requirement is 3.11
- Removed unprintable charater in RF Channel name
- Reworked packgen.py so that the code is RUFF compliant, working towards getting Github actions working
- Fixed simulator to load new HA snapshots
- Significant work on refactoring now with better async understanding
- Lots of RUFF updates
- Removed weird sleep constant that was the root of some CPU usaghe issues, hopefully this has gone now we're using a better async pattern.
- Shell and Simulator moving to async pattern in prep for deleting the sync API.
- Big refactor to help track down some obscure bugs, including a rare and hard to reproduce deadlock
- More robust pattern for transport socket usage hopefully clean-up potential leaking socket.
- Fixed lock issue when a command is being retried as the protocol lock is busy and the CUI won't exit until the timeout has been reached (this can be reproduced by making the simulator stop responding to watercare requests)
- Marked all sync APIs as deprecated
- Push this code to github and release it as it will be the last version that supports the sync API. It's getting too cluttered to maintain sync and async in the same codebase.
- Actually increment the version number and push to GIT before publishing. I might get the hang of this one day :-)
- Expose water heater internal sensors so they can be exposed in the home assistant integration
- Change min temperature from 15C to 8C
- Handle unnamed SPA (Issue #54)
- Prevent watercare from being out-of-range at the expense of knowing if it was ... it's more stable for users (#40)
- Fixed async importlib code from blocking by using loop executor
- Merged latest SpaPackStruct data from BenSeverson
- Merged pull to reduce asyncio sleep timeout to reduce processor usage
- Split radio strength & channel into two separate sensors
- Added some extra debugging around protocol sync lock
- Some unit_of_measurement values were the string "None" instead of the python keyword None
- Aggregate SpaPack error properties into a single text sensor
- Rebuild pack accessors from SpaStructPack.xml v36.1
- Merged fix for negative watercare values (thanks @EiNSTeiN-)
- Demote out-of-range spapack struct enum values to DEBUG and return "Unknown"
- Demote "No handler for xxxx" to DEBUG to declutter log files
- Going back to basics and watching the protocol from the iOS app, I noticed that the commands sent from the app don't use the same sequence numbers as the ones that are sent during connection, they run a loop around from 192-255 whereas the protocol ones go from 1-191 ... so replicate that behaviour in case it's confusing something in the system and adding to the instability of connections
- Moved protocol retry constants to GeckoConfig class
- Added 2 second pause between protocol retries to allow intouch2 EN module to settle
- Increased default timeout from 2 to 4 seconds
- Added radio channel and signal strength sensor
- Config change code could attempt to set result on a future that was already set leading to an unhandled exception that could result in the partial status update task being cancelled
- Disconnected facades now cleared out of the system correctly
- Added some more diagnostics to chase sporadic disconnects
- Moved config settings out of const class into their own class
- Added idle/active config settings and task loop for library to switch between idle and active config settings. An idle spa is one that is currently not processing any user demands, an active spa is one that has received a client request such as to change temp or turn on a pump. Active mode will stay on while any user demand is currently live.
- Replaced asyncio.sleep in various places with config_sleep which is aware of when the configuration values have changed which means that the loops currently waiting on these values stop waiting and can collect the new values.
- Fixed processor getting pegged at 100% but not using asyncio.sleep(0)
- Fixed simulator to respect names compatible with Windows
- Renamed some snapshots
- Updated README with simple async example
- Pull in reminders PR from @kalinrow - Thanks!
- Add unit tests for reminders
- Add async version of reminders - slightly different API as sync version returns time as first reminder
- Updated various clients to use reminders
- Supports both sync and async clients. The sync clients ought to be backward compatible but there has been a huge chunk of refactoring to get the async built and even though I've run all the tests and clients, it's possible there are issues
- Sensor for connection status is available early in facade lifetime
- Ping sensor available after spa begins connection sequence
- Re-added readline library to simulator as it was doing auto-complete for snapshot loading and was useful when testing, but added it inside a try/catch block so it won't upset Windows clients
- Manage ping failure and RF errors with retry mechanism
- Watercare regular refresh from facade
- Create Spa manager class to run the connection logic so that clients get cleanup opportunity when reconnections are needed
- Handle disconnected spas, ping failures, RF errors and so on
- Simulator can get/set accessors for experimentation
- Fix error found by Github workflow
- Added extra logging into to find out more about issue #28
- Removed readline library as it isn't supported on Windows and it wasn't really doing anything
- Added some extra doc for issue #18
- Added RFERR handler to client and simulator to start investigations
- Handle Watercare index out of range
- Accessors can now deal with Time type entries
- Added diag.py to aid tracking issue#27
- Added eco mode control to facade and shell
- Temperature accessor in new generator as it doesn't need to be handled at runtime
- Removed decorators.py
- Demoted some INFO logging to DEBUG to reduce HA log file clutter

- Watercare setting updated locally rather than wait for tub response to improve HA UI responsiveness
- Fast locator for static IP
- Demoted some benign debugging data that clutters log files
- Replaced "config" and "live" with "accessors" commands in shell to reduce direct access to XML
- Added "monitor" command in shell to give a live view of changes from other sources e.g. control panel or app
- Removed runtime reliance on SpaPackStruct.xml, this is replaced by the python code in driver/pack/*
- Accessor can handle byte, word, bool value updates if provided as a string (i.e. GeckoShell set command)
- Merge changes for variable speed pumps. Thanks https://github.com/los93sol
- Prevent new "pump" command showing in help UI
- Ensure STATP changes are cleared after processing rather than accumulating for-all-time! Thanks https://github.com/maegibbons
- Added some more snapshots
- Attempt to handle spas that return unsupported config/log versions
- Add ability to provide an IP address to the library
- Attempt to fix urllib3 requirement in pip install. It was in the wrong place
- More robust to missed packets during spa connection

- Moved all the functionality out of client.py and put it into GeckoShell class
- Try upload to PiPY
- Message encoding -> latin1 from utf-8 to avoid mangling raw bytes. This fixes
the turning pump 2 off when turning pump 1 on using
set UdP2=HIthenset UdP1=HI. There must be a better way to do this without switching between strings and bytes ... - Major source restructure to get ready for PyPI package
- Moved to pyproject.toml/setup.cfg for modern Python library
- Updated README.md with better examples
- Restructure code to be in line with Python library style
- Code auto formatted with Black
- Most pylint warnings/issues fixed
- Unit tests added for GeckoStructAccessor

- Dump state block & intro sequence so we can build a simulator
- Deal with temp decorators that might not be present on different modules
- Automation interface added
- Timeout retry of command to make it more robust on busy networks
The current facade control mechanism was based on my first experience with a single spa, and not much community feedback which has now changed, I now think that I need to update it following a greater understanding.
The first thing is that the intouch2 app only ever seems to send KEYPAD commands, and these are handled by the spa and seem to be converted into UserDemand changes.
When the UserDemand property changes, the spa also seems to make other changes to the data structures such as setting pump run times, light run times and so on, all of which we can see in the client apps and the simulator.
I have recently done quite a bit of work in the simulator and client to remove the old sync code and in doing so, I have refactored a good chunk of the base and got a better idea on how to improve it.
Sometimes the intouch2 app shows the state of devices based on the timers for some reason, at least if I change the UserDemand for the time then the app UI updates, but other times it responds to when the UdP1/UdLi status changes. This needs more investigation!
In the current code, the possible values for the user demands is a direct copy of the info that is in the SpaStruct.xml file, but if that was modified based on the information in the Config accessors, then the facade could be more aware of single speed, two speed and variable speed pumps that seem to be supported.
I've also recently updated the spa pack generator to include the structures for inMix and other Gecko products so that I can look into how to drive those devices too.
