Esp-homekit-devices: Will HAA work on Shelly i3?

[gijsstegehuis]

A Shelly i3 would make a perfect Homekit stateless button.
Can it be done using the current firmware?

It has three channels. Would it be possible to make it show up as 3 stateless buttons in Homekit?

[RavenSystem]

You can install HAA to Shelly i3, and you could create 3 stateless buttons in HomeKit, or 2 buttons and one movement sensor, or which you want. You have 3 digital binary inputs.

[gijsstegehuis]

Just received the Shelly i3's. Will test asap.
Do you happen to know the GPIO numbers for the inputs? it's not on their official website.

[RavenSystem]

You can follow circuit tracks, or you can setup a simple homekit switch and attach a GPIO number to it, and then change GPIO number and test it. You can create a bunch of switches too.

Here's the inner workings of the i3 with circuit tracks from input to the ESP

@lociii awesome! danke

[lociii]

Don't expect too much. I couldn't get it running with ESPHome as the inputs are floating and I didn't find any way to make them behave correctly.

[gijsstegehuis]

I am not into the hardware side of things, but isn't this wat the pull-up resistor is for?
There's a config setting for it in HAA.

[lociii]

Usually yes, but with pullup enabled, there is no signal at all.
I mean, try your luck. I didn't have some :)

[gijsstegehuis]

Thx. I will see if i can get it working.

[gijsstegehuis]

@lociii what sort of connector or cables are you using to flash the i3?
I soldered cables to a male/male header pin with 1,27mm pitch, but i can't get a decent connection to the ftdi adapter.

are there any standardized connectors around?

[lociii]

I used a self made 1.27 pitch connector too. You have to make sure they do in deep enough and are all pretty much the same length.

[AndreWillems]

just soldered some wires to the (small) connector. see pin-out on the picture. I flashed it the usual way like all other Sonoffs and Shelly's and it works perfect. I'm not using Tasmota or anything, build my own MQTT code for such IoT devices.

[lociii]

@AndreWillems was there anything special you had to change on your code to get the inputs working? Is it publicly available?

[AndreWillems]

@lociii, no nothing special. obviously changes the inputs based on the 3 switches from this Shelly device. Flashed it serial once and after I use OTA. drop me a mail if you want my source code.

@AndreWillems can you share the json configuration you used?

[AndreWillems]

@AndreWillems can you share the json configuration you used?

sorry @gijsstegehuis, I'm not using HAA or Tasmota. just wrote my own code once for Sonoff/Shelly and used this for Shelly I3 as well. no JSON config files.... but hopefully the picture with IO's can help you/others to make the appropriate JSON file ?

Hi AndreWillems

Could you provide your code to flash to the i3?

I tried esphome but can’t get the floating inputs to behave correctly.

[martinjuhasz]

I managed to get it working. You need to add a delayed_on_off. See my sample config here:

[gijsstegehuis]

For anyone stumbling upon this issue:
https://github.com/mongoose-os-apps/shelly-homekit just released version 2.5.0 which has support for Shelly i3
