Adjusting A 868mhz Gateway powering radiators By Brand tevovle to 400mhz

[thin rain]

I’m here asking if anyone has since on how I can pull my Tevovle gateway running 868mhz to a lower 400ect so I can add it to a gateway like Zigbee is this possible and how would I run about doing it or does anyone got an idea on how I would get it done it can only work by Google and Alexa I tried the Google SDK method but it’s lo tedious and doesn’t allow me to show my temps currently on dashboard

@north brook how would I inject it back?

[north brook]

So an example of something that does this over RF to control something with a stupid expensive RF smarthub bulslhit is..
https://github.com/rstrouse/ESPSomfy-RTS?tab=readme-ov-file

Which is built off of https://pushstack.wordpress.com/somfy-rts-protocol/

... Which admittedly may just be a little more complicated than I had initially thought insofar as things go; so the web api reverse may be easier to do if its available.

[thin rain]

With the api reverse method then how would one incorporate that would what integration would I need

[north brook]

https://vollragm.github.io/posts/web-api/

Is someone going through basic steps of this.

Followed by using something like nodered to inject it back into websites https://flowfuse.com/node-red/integration-technologies/rest/

Still semi complicated; but perhaps more straightforward ish

[thin rain]

Would it be possible to translate the gateway protocol into Mqtt using a mqtt bridge ?

Then connect mqtt up to home assistant

[thin rain]

Sounding like the best idea so far

[north brook]

that depends if the gateway allows you to poke it

which would require you to do some MITM stuff probably to intercept its traffic and peek

or rip it open and look for a UART and see if anything there is useful..

[thin rain]

But takes me back to the Q at hand once injected back into the website what do I do next how put that into HA

[thin rain]

Sounds much more complicated than the website injection

it is but this guy does a lot of stuff around IOT devices like that with videos. 😛

[thin rain]

Videos are better than websites leaning more towards that

[north brook]

his is mostly about just getting access and such..

[thin rain]

I’ve realised it’s 868mhz becuse it’s in Europe heating and radiators are ran on 868mhz

[north brook]

yep.

[thin rain]

Such a bummer making it so hard

For a friendly guy to just incorporate it into a dash

[north brook]

like.. if you could get a firmware dump it'd maybe be possible for someone to poke around and help remotely but that's just a maybe.

[thin rain]

What would the firmware dump lead to

[north brook]

sharing it; and then people can take a look remotely possibly.. tho that may also still contain your data too a little

🤷‍♂️

[thin rain]

Not applicable then I’m stumped

Not sure what to do that will give me the easiest answer

And Gurantee workin

I wonder do any devices on HA run on 868mhz

[north brook]

what devices are you trying to control?

that thing seems to talk to different things.

[thin rain]

I’ll send on one minute

[north brook]

you may very well also just be able to control those

[thin rain]

Avant DGI+ radiators

And the Avant DGi+ low level

[north brook]

so the simpler control if you wanted to just.. avoid all this would be like

smart plugs, and set the radiatiors to run at high or whatever speed when they're turned on.

[thin rain]

I’m listening

The radiators are wired in

😭

[north brook]

and then just end-running around the controller by using an esp32 with a thermometer or something

ah. bleh.. Its still possible just annoying

apartment or you own the home? 😛

[thin rain]

Own the home

I had a electrcition wire in all the radiators to a breaker

Because of the high voltage

[north brook]

I mean you could add a din rail switch on the other end. 🤷‍♂️

yeah, obviously.

[thin rain]

A din rail Wym by that

How would that help elaborate ?

[north brook]

like.. your power box has rails inside with blocks that the wires connect to rbeakers in?

probably? 🤔

[thin rain]

I got a rail with breakers and breaker box I do indeed

But how would that help me adjust the radiators on a dashboard

[north brook]

https://www.shelly.com/de/products/shelly-pro-2?_pos=7&_psq=shelly+2&_ss=e&_v=1.0

You could put this on the breaker side for the things

[thin rain]

Ohhh lemme look

[north brook]

basically turning them into dumb heaters; and then use a smart device with thermostat on it to control them on that side

[thin rain]

So it would lose the function for the Tevovle gateway that would be a waste

?

[north brook]

basically. 🤷‍♂️

[thin rain]

Ah crap spent 150€ on that 😂

[north brook]

issue being that.. you don't have most of the experience that would be required to attack it from the common angles and etc

[thin rain]

I agree

[north brook]

yeah, that ESPSomfy company wanted

200$ for a fucking box to connect to alexa/google

[thin rain]

It’s outrageous the prices they be charging

Thieves the whole lot of em

[north brook]

eat shit; https://www.printables.com/model/796688-espsomfy-rts-case made a 3d printed case and threw together an esp with a radio for that project for like 40$ all-in

[thin rain]

😂u should email a picture of it

“Made it cheaper dumb ah”

Such a bummer I can’t incorporate these damn Radiators with the capability the crap app has to be used in Home assistant

[north brook]

yeah, unfortunate how companies just love to vendor lock people.

[thin rain]

Would have looked so pretty in my dash

@north brook would u know how to make a webpage card size bigger in the dashboard i have an idea ill explain

Basically since it’s run of a website and it’s always online with my Ethernet plugged in I can just use the webcard to control the website with my tablet i it’s still there just on the right side and I can turn on radiators ect

Check analytics

As seen here it’s just not big enough

[north brook]

may need to change its size.. or aspect ratio or such maybe. https://www.home-assistant.io/dashboards/iframe/

[thin rain]

Thanks lad I’ll update u

I can’t get it any bigger it’s the same

Any ideas?

@north brook

[north brook]

yeah theres nothing I cann suggest off the top of my head here unfortunately.

maybe need to make the card larger on lovelace

maybe aim for something phone-sized ish?

[thin rain]

Wym by phone sized?

[thin rain]

How would I do that

[north brook]

I think it depends on the container size and whatever its inside.. maybe; I can't recall.. check lovelace formatting stuff.. perhaps? https://github.com/thomasloven/lovelace-layout-card

Effect height and such; see if you can get a bit more height

gonna go for now tho later.
