Ensto wireless thermostats

Hi,

I have few of these new Ensto bluetooth electric underfloor thermostats. They comply with the new EcoDesign requirements so there is bluetooth connection.

https://www.ensto.com/products/heating-systems/heating-control/combination-thermostats_nonecodesign/eco16bt-j/

They are so called combination thermostats so there is in-floor and room thermostats available. There is an IOS and android app available where you can do limited configs and see status/stats.

I think that there is no active work ongoing for adding HA support. Or is there?

I have been googling a bit. I found interface specification document for the thermostats:
https://github.com/EnstoFlow/apidocs/blob/0f6ba5e6b95edc3aae9cd65c6cd0710682918a45/Ensto_BT_IOT_interface_specification.pdf

My questions are basically:

  • Would there be a group of coders interested to join forces for this project?
  • Any “push-to-the-right-direction” from the more experienced thermostat/BT integration experts?
  • Really, how big is this kind of project? I am not an HA/unix expert so I would love to have some kind of scale for this project requiremets. Any idea?

I am currently having hassio running on RPi3 and BTLE connection is already in use for Xiaomi temp sensor. However, for the connection I am using ESPHome due to the very limited BT range in RPi3.

Hey!

Did you explore this any further?
A few months back i tested the connection from raspbian terminal and managed to receive some sensorvalues. But with my limited knowledge I didn’t get any further than that…

Seems that EnstoFlow github page is closed.

Someone have this BT IOT interface specification PDF? I asked from Ensto techical support but didnt got any answer. I had it somewhere downloaded but couldn’t find it anywhere anymore…

Eventually, my project with Ensto thermostats didn’t startup. I moved to new flat and I don’t have the hardware anymore.

I should have the documentation still somewhere. I will have look
