i tried and failed. will try create utility rate plan from scrath to see.
currently I can see Amber SmartShift works pretty well. and The most gain for the battery system with Amber is price spike period. Other tuning makes only very small difference that may not worth the effect if you are at home with a/c on.
Hi, I didnāt see this mentioned in the thread yet so thought Iād point out: The Telsa Fleet integration works great as another alternative to accessing powerwall (and vehicle) sensors and controls without need for separate token apps or paid fleet subscription etc. It is limited to the 200 API calls / day though.
Iām using Telsa Fleet + Telsa Powerwall integrations for the use cases in this thread.

FYI: From Tesla Support
About your issues with the API : that might be related to the Gateway firmware that was updated in July.
After version 24.4.0 it was no longer possible to have local access via the IP address.
This option has been discontinued as there is now an app for installers to commission the Powerwall. The access was not actually intended for customers, but primarily for installers.
Unfortunately we currently donĀ“t support API inquiries, but what I can share with you is this link which might help:

Hi, I have recently had a PW3 with GW2 installed.
Do any fo know which of the above HA integrations will work with that? I am looking to control the PW (not just monitor it). For example an integration that switches the export eveything Vs export solar only option in response to a SoC < x, or perhaps on a timed schedule? Does the feet API allow for that?
Any screnn shots of that please?
Any halp much appreciated.
(I should perhaps say that as yet I have not got HA - I am considering going down that route, but it all hinges on a useable PW3 integrtation. The overall goal is integrate my powerwall, heatpump, myenergi car charger & water heater and my energy suppliers smart tarrifs (Octopus UK).
I just got my powerwall and amber. I would love to know what you have done since this post. I have added the amber addon in
Iāve since scaled my automations back quite a bit: I wasnāt saving all that much and was finding some particularly sensitive electronics on one circuit were effected negatively when I took the house off grid (including taking the computer running HA offline 
)
Iāve still got all the sensors hooked up, but automations are all off except one that (attempts to) take the house off grid once the solar export price is well below -10 cents. I figure price protection should cover me for anything down that low, and Iām just covering any possible losses.
Note: for now, the ability to take the house off grid hinges on the HACS-based Tesla cloud integration. The native Powerwall integration used to perform off-grid islanding mode (disclaimer: I helped write that bit), but has since broken because of Tesla pushing a firmware update that removes local control over your own battery

Apologies all for my absence - Iām glad to see this matter is still in peopleās minds and further work is happening to allow us to better use our powerwalls.
Iām not using tesla fleet integration. As far as I know the powerwall is upgrading automatically but I am still able to reach its api locally using pypowerwall as a proxy. I need to check more closely.
Iām a bit worried as I feel Iām a bit in too deep with the local/custom integrations to swap again now, but as well if that will become a requirement, it will have to happen anyway.
My system has been working well as I want and need it and Iāve reached a point where it requires virtually no maintenance.
I notice no one replied to the question as to whether the Powerwall 3 is supported. For the PW 3 is it possible to:
- Turn on and off discharging to the house
- Turn on and off recharging from the grid
I wouldnāt see why not, Tesla are fairly consistent with their use of a single API to manage all devices.
However only someone with a PW3 will be able to confirm.
Iāve created three scripts to attempt to control the PW2. They arenāt effective. Has anybody got something similar working?

Looks like not many people are using a PW3 as I canāt get a definitive answerā¦
