Latching support

[garudaonekh]

Hello, Does your controller or ESP32 expander support latching valve?

Hi, What do you mean by latching valve?

[garudaonekh]

I mean pulse valve, which require only 50-500millisecond of power to turn on or off the valve. It's perfect for battery powered valve.

Using the OSPy, the shortest time for closing the multisensor relay to 1 second can be set (this would also work with valve). example: curl -s -O --connect-timeout 2 --data 're=1&run=1' 'http://192.168.88.237/0123456789abcdef' where run=1 is time 1sec for relay ON curl -s -O --connect-timeout 2 --data 're=0' 'http://192.168.88.237/0123456789abcdef' for OFF

Latching valve will require positive voltage to turn on and reverse negative voltage to close the valve. So if we use relay as workaround, we'll need two relays and 2 diodes.

in this case, a multisensor cannot be used to control these valves. This may be the subject of another version of the sensor with multiple relays and a choice of valve types. This is not possible at this time

Hi, in new PCB version 1.1 is suported two relay for latch valves... https://pihrt.com/elektronika/448-esp32-multisnimac-hw1-1-pro-opensprinkler-system i will need to add support to the firmware to support 2 relays...

Hi, new HW1.1 now supported two outputs for latch valves... https://pihrt.com/elektronika/448-esp32-multisnimac-hw1-1-pro-opensprinkler-syste m

sorry, i was busy and not seen this. why your latching valve has three wire?

Hi, here is how connect https://pihrt.com/elektronika/451-pripojeni-ruznych-ventilu-k-multisnimaci-esp32-ospy
