Hi,
i have a problem with my component. Here is the layout of my circuit, the yaml (configuration) and the sensory.py. I would like to query/pool these buttons (sensor.py) and I need to get under 500 ms as I can modify my code to have an optimal result. Thanks

You can never guarantee under 1 second on HA as that is how often it updates it’s input and output ‘registers’
So a time delay in a system of 1500ms will take ‘at least’ 2 seconds.
If you need less you will need to look at a more hardwired solution
As in a wire comes from a switch and goes to a bulb
You know - Faraday level switching.(Speed of light stuff)
What is the application, why do you need such fast response ?
HA is meant for home automation not controlling industrial multi-variable systems or nuclear reactors.
Normally having a light come on in one location to respond to another light being switched off in another location with a 2 second gap is not a problem, if it is, you’re using the wrong switch arrangement.
like the scheme shown above I have a device that gives me the status only if called, on this device I connected a button, the button continuously gives me the vaolre 1 only when I press changes the value to 0 and then immediately returns to 1. How do I intercept this state with a home assistant if I poll for a second?
I would also be willing to pay for a solution that works on my device and create an ad hoc component … but I don’t know anyone so experienced as to deal with the problem.
Your english is excellent but I can tell from the flow that your first language is something else.
Let me see if I can paraphrase what you are saying.
You have a button, that ony gives a 0 output when pressed, otherwise gives 1
And you are concerned that you will miss the button press ?
It sounds like you need a ‘delay off relay’.
So a button energises the relay, it stays on for … (say) 1.5 secs and this makes the contact for your device.
Depends what supply you have locally.
Another means would be to change the button to a switch and then operate on a leading or trailing edge (i.e. change of state). You can get latching buttons that would do this.
This does not seem right to me, why have a system that can’t pick up on it’s own switches ?
Normally s switch connected to HA will report the change, even if it happened 950ms earlier than the register gets updated. The device caches the change till HA receives it.
Is that close to your needs, or is there something else we’ve missed ?
Exactly, you understood very well, my system comes from an old home automation system 25 years ago, I wouldn’t want to change all the hardware because it’s fine, the problem that can’t progress in any way. The company that installed the system gives me also the communication protocol of their devices. I managed to build a custom component for HA and I can turn lights on and off and raise and lower blinds, my problem is the states. The “delay off relay” option is not possible for a number of reasons that are not cheap. I do not recommend changing buttons because it is not the optimal solution. So I have to find a software solution that simulates the correct functioning of the “switch”. In other words, this function totally independent from HA must poll (in less than 1 sec) on a list of devices (they would be my buttons) and expose the states to a register where homeassistant can access and read. It is easy to say but you can do it much more complicated.
Well, we can bump this thread occasionally to to keep it near the top of the list, hoping someone can help
But I think your constraints prevent an HA solution.
I hope I’m wrong
Good luck
Mutt
I have similar situation, Modbus RTU device with digital inputs. Buttons are connected to that inputs. So, how I can handle ‘button click’ event if it is around 100-300ms?
Hi there,
I’ve a similar situation too, so I give this thread my bump . This is my hardware:
one modbus over tcp\ip module with 32 digital inputs and some normally open momentary buttons
one modbus over tcp\ip module with 32 digital outputs, some relays for controlling lights
Then there’s an automation that commutates the n-th light on the n-th button press.
When a button is pressed “very shortly” the system misses the event and doesn’t trigger the automation, event if the DI module is able to pick it up. Also the same flow is working on node-red (cause I can set a 1ms pull time).
As Mutt suggested, changing the momentary buttons with switches (and updating the automation accordly) is working a solution, but in my case 2 switches take the space of 4 buttons (typical electrical box with 2 button per module vs 1 rocking switch per module)
Can the 1s be modded in some config file?
Has anyone found a better approach for having an automation triggered by a button press?
I have the exact same problem, an hardwired remote control that sometimes misses the button press because the 1sec polling is not enough for button detection.
It would be nice if that 1sec resolution could be lowered in some way.
I have same situation… Did you find a solution?
I was thinking since nodered can get the signals (even when less then 100 ms) nodered can pass it through to home assistant?
I did not try this yet but that is how I planned on doing this… Not sure if it will work.
If you found an other solution, I would like to hear it!
(I use a wago plc, but I only want to use the plc as IO module…)
At the moment I can read the input status very quickly (100ms scan time is safe, 10 is a bit unstable, but it’s not required in my scenario).
My plan is to scan the inputs and trigger an event on HA, but atm I’m missing the communication with HA…
It’s planned, but I’ve no idea on when I can develop something else on it…
. This is my hardware:
