OwnerA latching relay, also called impulse, bistable, keep, or stay relay, or simply latch, maintains either contact position indefinitely without power applied to the coil (wiki). In the electronics world, these relays have two contacts to open and close the switch.
You should define the ON pin first. For example, output 7 – Bistable relay ON, and output 8 – Bistable relay OFF.
Zigbee: Look for commands and examples for GPIO outputs. The firmware accepts all commands on the “Bistable relay On” endpoint.

After continuous configuration tests, the hardware function is normal in “Routing” mode under the same configuration, but the same error occurs in “End Device without Routing” mode. The level of Yi ‘xia will always be high when powering on, ha control, and the hardware has no report. I hope you can have a look at it. Thank you. Great author

Is the pulse valve in Burmet, Israel controlled in this way? It is positive pulse to open the valve and reverse pulse to close the valve

Sorry, but I don’t know this valve. The CC2530 chip generates digital pulses (0V – low, 3.3V – high).

Input pin1 injects high level and out5 high level for 1 second. Input pin1 reinputs high level and out5 high level for 1 second. Cycle. Pin1 is a button switch. Each time it is triggered, the polling output output high level. How much is your email? I will send you the schematic diagram for a detailed

You need the Pulse switch feature.

High level 3.3V output for 1s, one switch control, two IO output ports are required for on and off,

This is the valve website. I will connect a high-level trigger 12V at the IO output port, and the ZigBee module will output to the high-level for 1 second

There are too many devices connected to WiFi. I want to change it to ZigBee networking. Thank you

Ok. The “Bistable relay” implements the same logic.

I will purchase electronic modules for testing immediately. Thank you very much

The function can be realized after testing, but the initial state of power-on after power-off is not correct. The defined Bistable relay OFF GPID is always high level. Ideally, it is to remember the last switch state after power-off and then power on (correctly, it is to give a high level of 100 milliseconds once), instead of always high level. So my valve coil keeps burning a little bit, a long time,

Hi, i can’t understand how this bistable feature works: the name shouldn’t be “monostable”? I intended that this output has only one stable position and after impulse time has passed returns to the monostable position (ON or OFF). Isn’t it?
THen, it is possible to command this output by an input?
Can you add a configuration example?
