Hi Team,
new to Home Assistant (have been using OpenHab for quite some time but im finding its limitations so trying to see if HA will do a better job!)
My setup Raspberry Pi4. HA (latest). My MQTT is still on my OH server (not that I need it for this question - but so you know).
I have set up (and working) ESPHome on an ES8266 4-port relay board to switch some 12V roller blind motors up and down.
The dc motor (with its hardstops) is wired in relay common for Relay 1 and Relay 2
12Vdc+ is wired Relay1NC and Relay2NO
12Vdc- is wired Relay2NO and Relay2NC
The logic is:
Relay 1 on and Relay 2 off - no movement
Relay 1 on and Relay 2 on - UP
Relay 1 on and Relay 2 off - Down
Relay 1 off and relay 2 off - no movement.
This is all working using the .yaml of switch:
- platform: gpio
pin: GPIO16 #or GPIO15 to avoid brief power-on at boot
name: Relay1
id: relay1 - platform: gpio
pin: GPIO14
name: Relay2
I want to make a button setup where - if I press the “up” button, the blinds go up. if I release the button, the movement stops. (Eventually I will want to have a hold-for-a-few seocnds and the blinds will automagically gontinue to their endstop - but I’ll start with this simple setup first).
Similarly: with down.
in OH I could do this with a custom 3-way toggle switch,
or a blocky rule/script:
If (button-press(up) = ON & relay 1 is off) then turn relay2=on
else (if relay1 is on) then (turn relay1 off & relay2 on)
if button-press(up) = RELEASE then turn relay2=off
…etc…
I’ve searched the forums but they all seem to assume I’m using commercial blind equipment - or I building a set of blinds using mqqt (which I can do - I just thought I liked the integrations of esphome)…
I simply want a push button on my Overview etal. called UP… and another called DOWN.
anyway…
still learning .yaml and how this platform fits together.
Be gentle - as i learn I’ll try to stop asking stupid questions (I hope!)
