noah2000 in smart mode - setting target_power_w - possible ?

[mb76pl]

Hi all,
Is it possible to use the smart mode (zero mode) in HA and tell noahh2000 how much power to push to the home circuit ?
I did a little digging and found out that there is suppose to be input_number.xxxxxxxx_target_power_w parameter where you can write your desired power output. The goal is to have shelly meter connected to noah2000 directly without cloud connection.

Hi 😊

Maybe this discussion gives you some inspiration:
#86
it’s about NEO inverters, but the main point is to control them using HA scripting.

Do you know if Noahs keep the (default) output power value in flash or just RAM? I'm worried that using this instead of the 'smart' updates could mean wearing flash a lot.
Are there some registers that need to be set to make the 'smart' updates work besides setting mode 2?

Thanks! :-)

Hi,
Thank you for quick answer. i saw that threat and it could be a workaround to switch noah to manual mode and control it with the output limit... But, is it possible to do it the same way growatt cloud does it ? Is there a variable that is set by growatt cloud that sets desired power output ?

Hi, Theoretically, you can emulate a Shelly Pro 3 EM via Uni Meter, which can then use MQTT Topic as a data source where you can write the values. I actually use this myself, but I use my electricity meter directly (or rather the IR reader on it as the source for Uni Meter).

My Shelly meter already writes data to my HA's MQTT. The question is: is there a variable that noah uses when it's set in "smart mode" or "zero export" mode to set desired power output ? Must be, because growatt cloud sets it up somehow. Not only that, "smart mode" works with GroBro as well, because it forwards these messages from growatt cloud to the device and the device puts out so much power to match the usage indicated by the shelly device (which is shelly cloud connected)
Just to clarify my current setup:

• noah connected to GroBro, which connects to growatt cloud
• shelly connected to shelly cloud
• noah authorized in shelly cloud to get power usage data
• noah configured in growatt cloud in smart mode with shelly meter selected

Hi,
well, why don't you simply use the local binding of the Shelly to the Noah directly.
When you bind the two locally there is only direct IP communication in your LAN between Noah and Shelly
without using the two clouds.
This feature is available for several months now and does not require any additional components.
Take care

Hi Frank,
Thank you for the hint. Could you please say/show (maybe some screenshot) how can I do that ?
cheers
