    Hello cordially

    I would like to recommend some inexpensive WiFi module with the executive module (relays)

    The purpose of the implementation of a simple irrigation system using graphs in the Home Asistant, etc.

    I am interested in a module that would be free from the cloud , and I would have the ability to quickly configure, not necessarily rummaging through the forums to learn programming ESP32, etc.

    Although these modules are also interesting and probably some ready to convert to them.

    The module does not have to be domestic from Ali I can also download.


    Thanks in advance.


    Greetings

    Maybe just a Sonoff voltage-free 4 relay?

    From ali twice as cheap.

    Even no reprogramming needed, because it supports eWeLink and from there further to Home Assistant.
    I'm a proponent of cloud freeing anyway.
    I don't know what's sitting there, but it doesn't look like ESP, probably something from BK7231N
    Here's a question for @p.kaczmarek2 if something like this can be cloud freed.

    However, I found with ESP:

    But you have to reprogram. Upload Tasmota and peace of mind.

    Chat Bot recommended something like this:

    Sonoff 4CH R3 Mini , i.e. look for this module to be on ESP >?

    The modules linked by @gulson may work well. If @AoT_Hunter_PL you don't want to upload Tasmota yourself then I can do it, in that case write PW.

    If you want to search more, you can use the Electrode list:
    https://openbekeniot.github.io/webapp/devicesList.html
    You select which platforms you are interested in (e.g. ESP8266) and enter a keyword.
    Store names also work, e.g. Allegro. Allegro.

    Below is an example of the result:

    Then you click on the device name you are interested in:

    And it returns you to the topic of Electrodes.

    Here some four-channel:

    In my opinion, the easiest reprogramming. Because now I think the Sonoffs no longer use ESP.

    Most reliably on ESP, but on BK7231 also can be converted, on all platforms from the list below potentially can be flashed:

    Hello again, from what I have read the pro version of the sonoff is on ESP and most have reprogrammed.

    Double-check what you're buying, as there are also versions with WB3S (but these can also be programmed and controlled without the cloud):
