Chaining IFTTT rules

[twostar]

The KC868 (almost) makes a great PLC for home automation, but one thing I can't find is any ability to chain IFTTT rules.  The rule table has "IF NUM" and "THEN NUM" entries which look like they would allow this but they're all set to zero and can't be edited.

To explain what I mean here, it's the ability to say IF <rule 1 condition met> THEN <goto rule 2>, where <rule 2> allows testing further conditions.  Let's say you want to use the device as an alarm controller, so you want to test:

Code:

IF ( motion_sensor1 OR motion_sensor2 OR motions_sensor3 ) AND is_armed THEN siren

The IFTTT rules only allow OR or AND but not complex expressions like the above, so it'd have to be done as:

Code:

rule1: IF ( motion_sensor1 OR motion_sensor2 OR motions_sensor3 ) THEN rule2
rule2: IF ( rule1 AND is_armed ) THEN siren_on + rule3
rule3: IF ( rule2 ) THEN delay 10 minutes + siren_off

Another example is for an aquarium pump controller where the IFTTT is almost perfect except for the ability to chain rules, I can sense inputs, add timing delays, run the pump as an output, but I need the ability to connect multiple rules to do that similar to the alarm.

Is there any way to chain rules in this manner, and if not could it be added?

thanks, we will save your suggestion. which kincony board you are using now?

Just a KC868-A16 for testing, but I want to get more if I can use them for controls like this.

It would be very useful to have this because it would allow running a lot of automation directly on the board rather than having to use HA for it.  The KCS interface is a lot nicer than writing a lot of YAML, and having the board do everything itself avoids an external dependency on HA.

Another thing I'd looked at is converting the dry-contact input into a wet-contact so you can run a wire from an output back to an input and trigger another rule that way.  This is in theory possible because each input has a pullup to 12V which is bypassed when it's connected to ground via the dry-contact input so the opto LED is lit, by cutting the 12V line and connecting it to the wet-contact output you could drive an input directly from an output, but this is pretty horrible :-).  Having it handled directly in software without hardware mods would be much nicer.

Anyway, if you were able to add "Rule" output alongside the existing DO, AO, Delay, Protocol, etc, that would be very useful.
