MaxPower does not have effect on Channel 1 on SONOFF Dual R3

garageeks commented 3 days ago

PROBLEM DESCRIPTION

A clear and concise description of what the problem is.

I have a Sonoff POW Dual R3 running Tasmota 13.4.0(tasmota32)] I set up "MaxPower 300" command to switch off power when the more than 300 Watts are pulled. This works on channel 0, but not on channel 1. I tried "MaxPower0 300" like "Power0" style command that is applied on all channels, but it doesn't appear to have an effect. The documentation doesn't specify how to set power limit to a specific channel.

From the code, this feature do not support channels The command is 'MaxPower' without index and it applies only to the 1st channel

Behavior may be modified by 'MaxPowerHold' and 'MaxPowerWindow'

There is no command 'SetAllPower' this your error

@barbudor thank you for the quick reply. Indeed the fix I mentioned https://github.com/arendst/Tasmota/commit/d44104135e7194120715c3267236dc93e316bb8a is switch off both channel when Channel 0 threshold is met. I don't necessarily need to set up different power limits for each channel, it would be great that MaxPower would be effective on both channels.

I'll have a look if implementing multi channel is an option.

@arendst thank you, really appreciated. I'm always available for testing.

Give dev v14.1.0.3 a try.

Individual phases can now be configured and controlled with MaxPower2 300 for phase/channel 2 and MaxPower1 200 for phase/channel 1.

For backward compatibility MaxPower1 500 with any other MaxPower<x> 0 will result in all phase/channel power control.

@arendst Thank you for the quick update! I will have access to my test setup next week, will try it and provide feedback.
