Zero emissions. Zero compromises Log your vehicle data, air conditioning before driving or optimize charging… Countless ways to make your Tesla even smarter and integrate it into your smart home. [large] [image] Tesla Car & Energy | Homey Zero emissions. Zero compromises. Preconditions This app is using the Tesla Fleet-API. This API has a pricing based on usage. You get 10$ free for every month and if you need more data usage, you can add a payment to cover your costs. To use this API, you need a Tesla developer account. You can find instructions on my Blog or a short version in the car’s pair view. [image] Tesla: Nutzung der Fleet-API mit eigenem Entwickler-Konto – Ronny Winkler How to start? This app offers several devices you can add. Start with the car device. This connects to your car and allows some central functions to be controlled. Then add devices for special purposes you want to control like battery/charging, climate or location. [grafik] Every device has its own set of sensors, controls and flows. First add a car device. The pair view gives you some instructions how to create a Tesla deleoper account and it will request the client_id and client_secret from your Tesla app. [Post 2025_02_07 14] [Post 2025_02_07 15] Then you have to authenticate with your tesla account. Set set the scopes, the app should be able to use (select all as default). [HomeyPro_Tesla_AddDevice03] [HomeyPro_Tesla_AddDevice08] After adding the car to Homey, continue the pair view and register the app in your car (if you want to send commands). Klick the button to start the app registration. The link opens in Tesla app. If it’s opened in the browser, please scroll up and open it in the app. [Post 2025_02_07 16] [HomeyPro_Tesla_AddDevice07] [HomeyPro_Tesla_AddDevice10] [HomeyPro_Tesla_AddDevice09] Bluetooth LE support The app suports Bluetooth LE access (from version 3.0.0). You need a good BLE reception between your Homey and your car. Plase your Homey in range or use a HomeyBridge as BLE satellite with your HomeyPro 23. BLE is optional and in addition to cloud access (via FleetAPI). If BLE is activated, the app tries first to connect via BLE. If that’s not possible, the FleetAPI is used. Check my Blog for more details… [image] Tesla: Bluetooth-Verbindung – Ronny Winkler Tesla Telemetry support The app supports Tesla Telemetry (from version 4.0.0). Using Telemetry, you can get realtime data from your car. As a prerequisitee, the app must be added as car key. Then you can just switch on Telemetry in car device settings. If activated, the car sends its updates in realtime to the Telemetry server that is provided by me as developer. Your Homey connects to the Telemetry server and gets forwarded the realtime updates, Another advantage is that API usage becomes cheaper because you can use much more Telemetry messages than data requests, If Telemetry is on, you can deactivate data polling in car device settings. Check my Blog for more details… [image] Tesla: Fleet-Telemetry – Ronny Winkler Additional infomation On my website you can find additional information. Additional information will be added as Blog posts. [grafik] https://rwdevelopment.de I will provide basic information about the app and the api (technology and security). And in the blog I plan to show use cases and examples. There you can register for a newsletter to get updated when a new blog post is published. And you can ask for further blog posts about examples, HowTo’s and technical insights What API is used? This app uses the Tesla Fleet API. Details... You authenticate with your Tesla account (oAuth) and allow the app to connect to your car. In addition you have to register the app in your car (like a key card) to allow the app to send commands. Vehicle data is determined using interval retrievals. These request won’t wake up the car. But if the car is asleep or offline, the app won’t get updated data. To control you car, commands are sent. There are two variants: Fleet API: The app sends simple https requests to the Fleet-API. Pre 2021 S/X models have to use this option Tesla Vehicle Command Protocol: The app sends encrypted and signed commands to your car. If the app is registered in your car as key, these commands are allowed and processed. This allows an end-to-end encryption and security policies. You can remove app command access in car security settings or remove the app completely in your Tesla account. Dependent on your role (owner/driver) your car access could be restricted and it’s not allowed to register the app in your car. This can happen if the leasing company is the car owner. Please contact the leasing company and/or Tesla in this case. What is a Tesla Client-ID and what do I need to keep in mind? Details...

This helps me to finance the necessary server that’s needed to provide the apps public key and the proxy server that is used for the command API. Thanks.

Thank you for the update. Really appreciate it! Can imagine a double feeling here, after all the effort put into this app. Hope a sustainable solution pops up somewhere soon!

Tesla…won’t be buying another

That’s really sad. I just finished my flows (which took several evenings…) for charging our Tesla’s using dynamic tariffs and managed load balancing to be included (bought charger without load balancing as I could manage with Homey and P1 data). In fact, it was the main reason to purchase my Homey and P1 device… Same time, for managing charging, controlling Tesla is not really required. I wondered why only a few charger brands can be controlled form Homey. My Ratio 6 charger can’t (unfortunately). But same time, they all use the same protocol (OCPP) to control their chargers. So, somehow it should be possible to control charging by the charger instead of the Tesla. A challenge could be that the charger can only be connected to one CPO and in my case it’s connected to one to enable paid charging (as my wife has a company car and charging costs should be paid by her employer). I think co-operating with this CPO’s is a bit easier than with (arrogant) Tesla. Nevertheless, other functions to control our Tesla’s, like climate and location, were also a (very) nice to have. I created some awesome flows to make live more comfortable (like pre heating the car), which we will really miss. I really hope Homey can manage a suitable API-access again. Same time, it’s disappointing users get mailings about all the good Homey news only and are not pro-actively informed about this kind of (significant) changes. In my case I had to notice the app was no longer working today (no information in advance), while I was still working on the flows last week. That’s subject to improvement for Homey. If I had knows a couple of weeks ago, I could have saved a lot of money and even more hours I now lost.

This is a community app. And the forum is the only channel I can talk to users. :man_shrugging: Tesla announced the price change in December, than gave a second month free access. Abe tried to get in contact since december. Currently we have no partnership and just the incredible high API price. That makes it impossible to continue the app atm. You are welcome to address complaints to Tesla. Perhaps better Tesla should get user feedback. Perhaps something changes if many users are addressing there needs for an ecological energy saving using such apps.

Hi Ronny, I don’t think there is any reason to blame you. If there is one main ‘victim’ in this case, I think it’s you after spending so much time and effort in developing this great app. I understand you can only post here, but Homey can contact (and inform) everyone that purchased a Homey, for example by e-mail (mailings). They didn’t and many users will be ‘surprised’ today by notifying the app stopped working. I don’t think complaining individually will impress Tesla (also considering the CEO’s attitude). Even when it’s initiated from ‘Homey’ (for example invite all Homey user to sign a petition), the success ratio will be limited (a relative is working there and I know even the (Dutch) staff has ‘near 0’ influence), but at least a collective will impress more. I just checked the Tesla API information, but I’m not a developer and don’t understand most. However, I noticed they offer Fleet Telemetry as an alternative (but I assume you had chosen that option already if it was really a feasible solution).

[image] Marcel_R: A challenge could be that the charger can only be connected to one CPO and in my case it’s connected to one to enable paid charging (as my wife has a company car and charging costs should be paid by her employer) Which charger do you have? If it’s Alfen you can also check out this topic: Alfen Eve Single Pro support - #92 by HScholing. Maybe for other chargers there are also apps that behave differently then managing it through a CPO.

FleetTelemetry needs infrastructure, own server etc. That can’t be handled from Homey. That’s mainly for the BigPlayer offering their apps on a cloud solution. And even witb Telemetry you have to deal with API pring that’s not userbased.

I have a Ratio charger with RFID and use (of course) the Ratio app. I contacted them last weeks, as I first wanted to use Volttime cloud to control the charger (e.g. for load balancing). That way, I didn’t have to control the charging level via Tesla. But, Ratio replied I can only assign 1 CPO (which I can understand), so I had to choose between Volttime (so I can post commands from Homey to Volttime and Volttime controls the charger) or CPO (to invoice my wife’s employer when she is charging). But I couldn’t find a CPO that can be ‘controlled’ by Homey (not only to manage load balancing from Homey, but also to set charging prices based on dynamic power prices). That’s why I choose to use the CPO for billing (Homey not involved) and Tesla/Homey to manage load balancing and charging on ‘cheapest hours’ (several flows). Maybe a bit ‘off topic’, sorry for that…

I use EVCC to control my Alfen Eve Single Pro. The Alfen Eve Single Pro can work with a backend (like Road/eFlux for financials) and work with EVCC at the same time. EVCC can by controlled by Homey by using MQTT. May be this can help you, howeverI don’t see your charger in the extensive supported chargers list by EVCC ( Chargers | evcc - Sonne tanken ☀️🚘 ). EVCC is actively supported, you might try to contact them of they could add your charger as well.

[image] RonnyW: Perhaps better Tesla should get user feedback. @RonnyW you’ve been a hero mate, much appreciate your efforts and nice Tesla app. It has been working flawless for me till it lasted. Yes, Tesla should get the feedback. Guess I’m lucky enough to have Tesla as a company car and the freedom to more or less choose the car I want. Two months until the current lease is gone and DID NOT ordered a Tesla. A smart charger such as Wallbox would be OK to cover most of my needs related to charging anyway. Cheers Ronny, hope to see more nice apps by you.
