How to block switches rules until A0 is high

[zakdma]

Hello, guys!
Could you please help me with such a problem?

Tasmota 14.4.1 on Wemos D1 mini.
I have switches (mechanical) but there are no relays as I use rules to send WebSend commands.
SwitchMode set to 1 for all switches
Switches connected to GPOOs: 4,5,12,13,14
So all free pins except A0 (GPIO17) are occupied
Rules:

Rule1 
ON switch1#state DO WebSend [192.168.0.160] POWER %value% ENDON
ON switch2#state DO WebSend [192.168.0.161] POWER %value% ENDON
ON switch3#state DO WebSend [192.168.0.162] POWER %value% ENDON
ON switch4#state DO WebSend [192.168.0.163] POWER %value% ENDON
ON switch5#state DO WebSend [192.168.0.164] POWER %value% ENDON
BREAK

So all is ok:

• I closed the switch - remote relay closed.
• I opened the switch - remote relay opened.

I pulled A0 up to 3.3v by the 10k resistor.
I need to block all switch's commands in case A0 is HIGH and allow them in case A0 is LOW.
Is it possible?
Thank you in advance.

Simple one: do it electrically. Instead of sending your control signal to A0, use it to feed the common pin of your switches instead of ground.
😊

Now with Tasmota rules, if this is not happening to often you could use another rule set to enable/disable Rule1 (and also send a 'Power 0' to all WebSend destinations)

Thank you!
I implemented it in that way but there are security issues with such an approach.
There are a fingerprint sensor (FP) and 5 buttons in the external box. The external box is connected to the internal box (controller) using a multiline cable.
When I touch the FP it connects GND on the button's common pin for 10 seconds. During that time I can press the button and GND will be connected to the controller pin that detects the switch and sends the command to open the door. So far so good.
The fingerprint sensor is connected to the internal box using 6 pins one of them is GND. All communication is encrypted, so 3-rd person can't trigger FG relay to enable buttons common GND pin even if they break the external box. But there's a direct GND pin on the fingerprint sensor, so a person can just connect it to the button pin and open the door even without need to trigger FP relay. That is the problem, and that's why I need to disable commands sending in case FP is not triggered.
I hope you understand what I mean.

So the question is open. I still need to detect that FP is triggered and disable commands if not.

Fully clear

I have already answered that you can use the 2nd rule-set (Rule2) to triggered on A0 level and enable/disable the first rule-set (Rule1)

Another option as SUPPORT_IF_STATEMENT is now enabled on ESP8266 too (if I'm correct) is to use a condition

Somehting like that (not tested) should work

Rule1 
  ON switch1#state DO if (%var%1 == 1) WebSend [192.168.0.160] POWER %value% ENDON
  ON switch2#state DO if (%var%1 == 1) WebSend [192.168.0.161] POWER %value% ENDON
  ON switch3#state DO if (%var%1 == 1) WebSend [192.168.0.162] POWER %value% ENDON
  ON switch4#state DO if (%var%1 == 1) WebSend [192.168.0.163] POWER %value% ENDON
  ON switch5#state DO if (%var%1 == 1) WebSend [192.168.0.164] POWER %value% ENDON

Rule2
  ON analog#a0<400 DO var1 1 BREAK
  ON analog#a0>600 DO var1 0 ENDON
Rule2 1
Rule2 5           => "mode Once enabled to not strigger continuously"

Note the BREAK in your exemple does nothing. Here above is a correct example usage of BREAK.

You need to place the rule ON analog#a0 in a different rule-set in order to enable the Once mode
The once mode means that the DO will be triggered only once when A0 goes below 400 and not continuously. It requires A0 to go over 400 again to be able to trigger again when A0<400.

That's a cool approach. From the docs, I previously knew that if statements are not supported out of the box, I have to recompile sources for them.
I will try it and notify if it's working as expected.
Thank you very much!

That part of the doc might need update
The BUILDS.md , my_user_config.h and CHANGELOG files clearly state that it is now enabled both on ESP8266 and ESP32
