Integration with Davey Lifeguard

I have a pool salt water chlorinator, brand Davey, type Lifeguard and I have been told this is one of the most commonly used chlorinators. I have been searching, but it looks like there is no integration with HA. This would be very interesting as there are many parameters for the water quality in a swimming pool, like the pH, ORP, salinity and temperature. Also it has several modes that could be controlled via HA.

So, if anyone has more information about it I’m happy to hear from it :grinning:

I would also be interested.
In the meantime, I will try to read the App requests.

How do you do this, as I can contribute also maybe?

I can only get to it beginning of September so if you could help that would be great.
Would be using Proxyman (https://proxyman.io/) to intersect the requests.

Would be great if you could have a look at this :+1:

I have installed the app on my iPhone to trace the communication…

As this is my first time, I have to admit it’s pretty hard but I see communication to URL: https://app-measurement.com/a as I the User-Agent: Lifeguard/154 CFNetwork/1410.0.3 Darwin/22.6.0

For sure this is the Davey Lifeguard.

I can also see the CONNECT and POST command when using the app. The distinction between the several POST commands is none. So, I don’t know where to look in particular…

@kegelmeier do you still have the motivation to do this? I am happy to help but I have little experience

I’m surprised nobody in the world is interested to integrate Davey Lifeguard, while it’s one of the most popular products for swimming pools… Also unfortunately, the supplier hasn’t integrated anything for their interest.

I also have a Davey Lifeguard installed at my pool.
Already did some research on the API requests with mitmproxy. The API uses OAuth and some requests to a domain called dwprod.co to gather its data. Should be easy to build some RESTful sensors on top of that. Mainly to gather information about ORP, Salt and pH.
If I had the time to implement an integration I would do that, but for the time being RESTful sensors will also do the job.
I will provide my YAML when I am ready.

Interested as well, little out of my league to develop the integration.
But if someone is willing to provide the assistance/guidance I can be the hands on person with an active setup.

Any news from your side @derstrassi, in case I can help with my limited ability… please let me know…
