Why am I struggling with this simple rule

[PeteRepeat77]

Help needed..

I have tried many times. Multiple ways.. read a reasonable amount.. so this post doesn't come without trying. It's still early days for rules in tasmota for me, but I have spent considerable time already on this.

I am trying to send a servo motor (dimmer) to a certain value if BOTH two switches (power2 and power3) are closed.

This is what I thought would work..

Rule1 ON Power2#state==1 DO if (Power3#state ==1) Dimmer 70 endif ENDON ON Power3#state==1 DO if (Power2#state ==1) Dimmer 70 endif ENDON

I have tried assigning variables and using maths to do this... I just couldn't quite get that to work... Partially yes.

I originally tried an AND statement in the trigger, but then read that conditional statements can't be used for triggers

Because you seem to assume that trigger expressions with # can be used anywhere outside of the trigger before do. Using the value from the trigger event would be %value%, which obviously would be the same power channel. For context, triggers is "when something happens", not "look at a field".

What you do have is https://tasmota.github.io/docs/Rules/#rule-variables including some features like power channels (but not events).

Ok so I've now added variables and this seems to work. Var2 stores the value of power2, var3 for Power3. I couldn't get the if statements working with power2 etc.

Rule1 ON Power2#state==1 DO backlog var2=1 ; if (var3==1) Dimmer 70 endif ENDON ON Power3#state==1 DO backlog var3=1; if (var2==1) Dimmer 70 endif ENDON

I have another rule that when the power states change to 0, then set the corresponding variable to 0.

I'm sure this is the long way around. However it works now.

Why did you not follow my specific recommendation?
Indeed, you do not need "the long way around" with keeping variables updated.

I did try, thanks for the suggestion. However I got a little lost.

You saw this part of the page?

%power1% to number of power channels

[PeteRepeat77]

Yes but when I put power3==1 (instead of var3==1) into the if statement it didn't seem to work.

Ah I see now that I may need the % around it. Still muxh to read, much to learn the basics of tasmota rules.
