[APP] SENZ-WIFI (nVent Raychem)

Hi there!

I’ve been using this app for a few weeks now, and it seems to be working beautifully together with my Senz Wifi device :blush:. Well done :pray:

I don’t know the limitations of the api, but is there any chance additional functionality can be added to toggle power (on/off), and select a specific program (program 1, 2 or 3) using flows in Homey? I’ve got the Homey Pro hardware and I can’t see those options within the 1.4.7 version of the nVent Raychem Homey app, but I’d love to be able to select different programs during different seasons, or based on thermostats triggering a flow when the room temperature reach a certain treshold. I also don’t need to heat the floor during summer so being able to turn it off would be awesome.

Thanks for putting in the effort and taking the time to develop this app.

Hi there!

Thank you for your kind words.

Unfortunately, as you already mentioned, this is not possible due to limitations of the nVent API.

It is possible with variables and date triggers, but I guess it is not very convenient.

Best regards,
Edwin

Hi!

Just wondering! is there any chance to get the usage out of the Senz! eg. how how much kw it is using at the moment and total between 0000-2359?..

Hi Jan,

This data is’t available in the NVENT API.

Best regards,
Edwin

Hi,

all my thermostats are offline, I guess it’s API problem?

Getting this when trying to authorize from Homey :

{“success”:false,“message”:“Invalid Token: undefined”}

Hi @Sharkys,

Yes, it is the API. When I try to get all the devices via Postman, I get this error:

{
  "Messages": [
    "Internal Server Error."
  ]
}

@evdpol thank you - luckily the official app still works.
@Patrick_Hendrickx , thank you so much.

Great to still see you around, I/we (community) appreciate. :+1:

Hi all, we had to restart the server, but all thermostats are back online. Sorry for the inconvenience.

No problem. I am glad it worked out.

Hi! Thank You for the Information! and the App!
It’s not in the Senz Mobile App either, in a good way so it makes the thermostat a bit dumb.

Hi guys,
any news on latest API issues I observe for last 5 days, please ? Seems that genuine app still works, but API reports ALL thermostats offline…

I am experiencing that the app is broken since about a day. Are the servers down? The official app seems to be working fine. Anyone else with the same problem?

Literally just message above yours…

Yes. But I thought that it might be unrelated since I only started having problems yesterday.

At least we are two now. :slight_smile:

Yeah, it seems so, but I have also monitoring for errors, so this is why I notice the problem immediately. But it’s API / Raychem issue, so I guess here can’t be done much ;-(

It is up again for me.

Unfortunately, API seems to be down again ;-(

I agree.

I have written to raychem using their contact form.

Please consider doing the same. :slight_smile:
