Shutter Interlocked relays (both) go ON after reboot

[kbaras]

PROBLEM DESCRIPTION

Hi!

I have a serious problem with the latest Tasmota release.
I have a shutter configured with two relays, with ShutterMode1 and the relays are interlocked (1,2). As I am using inverted relays the configuration has been set accordingly (with relay_i both for relay1 and relay2). It works fine at normal operation (the interlock as well, so if one of the relays is turned ON and the other is clicked to turn it ON than the interlock automatically turns OFF the other relay so you are unable to turn ON both - which is the expected behaviour).

Problem comes after I restart Tasmota (plugged out the power source and plugged in again) then both of the shutter relays are ON after startup! After clicking on either of the relays the interlock intervenes and it turns OFF the other relay so from this point it works fine until the next restart...

I have a separate inverted relay configured additionally and it does not start with ON state.

Initially the PowerOnState was 3, but I have also tried with 0 but it did not help...

TO REPRODUCE

• Configure two inverted relays into a shutter with interlock group
• Cut the power source and add power again (reboot)
• Both relays will be ON

EXPECTED BEHAVIOUR

After powerup both relays should be in OFF state.

SCREENSHOTS

[kbaras]

Sorry, I forgot to mention that I am using the Generic (18) configuration with a Wemos D1 mini - but the hardware is probably not so important here...

[kbaras]

Ok, I have recognized that the problem comes up when I configure D1 and D2 as the relays for shutter...

[stefanbode]

hi, pls check that savedata 1 is set. then first check on the poweronstate. this must be either 0 or 3, I do all my tests with 3, the situation with both relay on only can happen if the relay where ON and then you do savedata 0, in this case the state is always wrong on both ON and will not updated, The shutter driver cannot override the interlock 1,2. pls also check that the interlock is also set with interlock on. My command to get it fixed:

savedata 1
interlock 1,2
interlock on
poweronstate 3
power1 off
power2 off
restart 1

[stefanbode]

this can also be a reason. pls try so63 1

SetOption63 Set relay state feedback scan at restart (#5594, #5663)
0 = Scan power state at restart (default)
1 = Disable power state scanning at restart

Ping @kbaras to test latest development version with the mentioned settings.

[stefanbode]

I have an idea where it comes from. Maybe the inverted relay is the root cause. If I think about it it's getting more likely. I need to setup a testbench to check it again. The use case is quite rare. And it was not part of the testing.

[stefanbode]

Double checked the Relay_i and cannot reproduce the error. Device react as specified. @kbaras Please comment on the suggestions. Otherwise we will close the case in a day or two.

[kbaras]

Hi!
Thank you for handling the issue.
In the meantime I was able to "workaround" it by using different pins for the shutter (D5 and D6). As I've mentioned I experienced the problem using D1 and D2 initially.

[stefanbode]

Sorry to say, but this makes no sense at all. May be a pullup or pulldown might be the case. Here setoption63 1 can solve this one. I use this as a default.

[Jason2866]

Closing. Using non restricted GPIOs is always better. Restricted GPIOs can generate not wanted side effects.
