Id: relay # optional, but useful if you're going to call this from a physical buttonĪnd that’s it. Pin: GPIO12 # change for the actual GPIO you are using Name: "Valve Control" # or whatever you want to call it In any case, setting up a relay in ESPHome is very simple - see below. Contactors are like big relays, you can get them at an electric supply store, and they can be controlled with a small amount of current. If it needs more than 10A, you can still use a relay to control a Contactor with sufficient amps. You’ll have to check the spec sheet for the electronic valve you’re using. The only thing to watch for is how much current it uses to move the valve - for water flow, it can sometimes be higher than you think, which means a 10A relay such as you commonly find in Sonoff devices, or standard hobby relays, might not be enough. You don’t mention what valve you’re using, but I assume that it’s something that can be activated by a relay.
Hi, great to hear that it’s working for you.
#WATER FLOW METER HOW TO#
Therefore any idea how to connect this properly ? I changed then the connection and put this resistor between 3.3V(ESP8266) and GPIO12(ESP8266)Īnd started to receive some pulses but those looks like misscalculated. Therefore decided to connect 3.3 V to Pulse Output, GPIO to Common on Pulse Meter and GND of ESP8266 through 10k resistor to GND of ESP8266īut after that started to reset my esp8266 at every pulse received. Therefore based on many posts here, of this sensor flow meter which using 3 cables i started to think, that i have to power up somehow GPIO to count it. When i used simple magnetic contracton with other esphome function it was reporting open/close door with connection to GND and GPIO, but here with this pulse_counter platform was not able to count anything using contracton or pulse meter. In general i`m confused how it should be connected from the electronic point of view. I flash my esp8266 connected this magnetic pulse sensor to my GPIO and GND and has nothing in the measurement. Theoretically simple as that, this pulse add-on is giving 1 pulse per liter or 1 pulse per 10 liters, depends of the installation on this water meter ( )
#WATER FLOW METER FREE#
My water operator installed at my house water meter with measurement addition which is not used by them.īased on the technical documentation, there are 5 cables which are free to use (different use cases, flow direction, pulse measurment, reverse pulse measurment, fraud, etc ) Therefore i have some question, might be dump but we will see
For the first thanks all for posting a lot off useful information around.īut missing unfortunately some measurement around magnetic hall.
