Do you guys have your valves configured in individual rooms? I have some valves in the same room and grouped them in the Netatmo & Homekit environment.
I suspect that when this is the case, the battery level is not provided for these valves as I don’t see the individual valves in Home Assistent. In the rooms where there’s only one valve this property is populated.
Would you guys know if there would be a way to get all the individual valves?
Right now there is now way in HA to get individual valves. Sorry.
Any idea why is this not working for me?
Can you be a bit more specific?
Created the battery level sensors in the yalm like in the example of OP. The sensor creates succesfully but it gives me the state “unkown”.
I’m using homekit to control the valves and the opentherm relay since the netatmo integration doesn’t work with the new opentherm relay
Then you have to look up the attributes from your homekit entities and edit the template.
Unfortunately I don’t even know how to begin to do that. Messed around a bit in the entity and developer tools but couldn’t find any clue.
There are multiple problems. For one, you are using homekit whereas he is using the Netatmo integration, which provides attributes you probably don’t have. Further, such template sensors are not meant to be simply copied and pasted if you don’t have a basic understanding how they work. I’d suggest to read the docs on templates and template sensors and start playing in the dev tools section where you have all states and attributes available and can freely build up the desired template that fulfils you needs.
hi, i have multiple valves in multiple rooms, what I see:
so battery_level available for romm with multiple valves and values are strings, not int
well, all valves are firmware v85
i would like to all valves with battery_level attribute, string values are ok 
Hi all!
I’ve created the sensors with your config too and it works at least for the rooms with a single valve. The room in my case with 4 valves and the thermostat I think I have the thermostat value.
But the problem for me is that I get “full” or “high” and I don’t know how to get the numeric value in percentage.
Is it possible to get it or Netatmo has changed it’s battery value representation?
Thanks!

Hi,
I actually have the same problem on my side. Also had the problem where some random valves would not send their battery states.
At the moment all of my valves are communicating their battery states but only in “high” “low” status.
I believe they changes something within their api.
Maybe someone with better code knowledge as I have might figure out how to pull data using the rest template like for this case : MyStrom Switch v2 - #7 by davosian
Here is the api doc : Netatmo Connect | Energy API Documentation
There is no such value provided by the API. The battery state is only reported as as a string (high/low) or as an absolute value which we then only can interpolate from “educated guessing” (which was removed, because it was unreliable).
Hi, i don‘t have any valve which provides the Battery level sensor. How do i get them?
I only have one valve in each room. All on v85 and the Relais is on v222.
In the Last days i only got a Message from netatmo App That my battery died and heating started to fully Open the valve. I want to fix This so i can change batteried right before They die and Not After.
Thanks for any tips!
Wow i am dumb. Thank you very much!
Certainly not dumb. It’s easy to miss and relatively new.
Maybe i am hacking this post, if so please let me know.
I do have the sensor for each valve
sensor.foobar_battery_percent.
The problem Is that this value does not update.
Last update was 2 days ago (when i restarted).
In the meantime one of the batteries died and was replaced. But there is no sign of such event: home assistant happily reports 75%.
Do i have to trigger an update?
Thanks
The attribute used in the template above is not available anymore and has been replaced by battery sensors. So there is no need for the templates anymore. The integration handles that for you.
I’m fairly new to HA ( running in a VM on unraid) but can someone tell me why any of my netatmo valve (or my thermostat) sent their battery state ?
My question is a little bit offtopci, but can someone tell me that is the valve position (percentage) available in HA for Netatmo radiator valves?
