New Interlock TASMOTA Feature #119

Closed meingraham closed 5 years ago

meingraham commented 5 years ago

@stefanbode - First, thank you for your Interlock feature TASMOTA PR.

Have you looked for this feature in other issues and in the wiki? Yes

Is your feature request related to a problem? Please describe. A relay cannot be part of two different interlocked relay groups.

The new Interlock feature ported from this fork over to TASMOTA main allows great flexibility in defining the groups of relays to be interlocked via the software configuration. One can define multiple groups and can define which relays are part of each group. However, a relay cannot be part of two different interlock groups.

Describe the solution you'd like In my use case, I need to be able to interlock a relay individually with two other relays as separate interlocking groups. I have a ceiling fan speed setting scenario where:

In this scenario, relay 1 can act independently from relay 2. However, relay 3 should never be latched when EITHER relay 1 or relay 2 are latched. Using the current Interlock syntax, the groups would be defined as:

Interlock 1,3 2,3

In other words, define the interlock groups as follows:

A. Relay 1 & 3 B. Relay 2 & 3 C. Do not interlock Relay 1 & 2

Interlock 1,2,3 won't allow 1&2 to be on at the same time, which the circuitry in the fan requires for selecting Medium speed.

Describe alternatives you've considered Use Interlock for one of the relay pairs and use Rules for the other.

Thank you for your consideration of this enhancement.

Functionality will be replaced with the next sync.

Stefan - replaced with your mods that Theo merged into TASMOTA or completely overhauled by you? If the latter, will the new functionality allow the type of interlocking I described above in detail?

Thanks.

I have to take a look into the new implementation. It is definitely better than mine. From the concept your use case should work. Maybe some tweak is required
