Wall switch that toggles?

I have Home Assistant running (very simple system) without any issues,. Great. I have a couple of SOnOff devices (for now, custom programmed) running just fine. Again, no problem.

The only, very minor, issue I have is this: One circuit that is timer controlled uses a regular wall switch to control the light. To make it work with Home Assistant, it is necessary to toggle the switch on/off (cause the pulse from the toggle is picked up by a SOnOff device). While I have no issues with this, this is not entirely obvious.

So, my question is this: Are there any wall switches that when one pushes the lever up or down, it causes a ‘pulse’ to be sent? Or, are there wall switch devices that can be easily integrated into a Home Assistant system (without the need for the switch to transmit data to some system off-site and then have info pushed back to the system).

Thanks.

You should be able to do it with a momentary switch.

Regular style switch

Decora style switch

Do you know the voltage the sonoff device is sending? 3 or 5 volts, correct? These switches are rated up to 24volts.
