How to connect

Homey has written an extended article on how to add your Solyx WaterAccu to Homey: Connecting Solyx Nymo with Homey – Homey Support

FAQ

  1. I cannot seem to control the Nymo using this app?
    This usually has one of two reasons:
    a. The firmware on your Nymo does not support the Homey integration. You will need at least version 3.01; the installed version is briefly shown when the Nymo is powered on. If you do not have this version please contact Solyx to discuss options.
    b. There is an issue with the 433 MHz signal, which can be influenced by many factors. You can try moving your Homey near the Nemo the see whether that resolves your issue, or you can adjust the signal offset in the settings (also explained in the Homey support article).

I love the idea, but the device is way too expensive (€650). After 01-2027 it will save you the tax (€0.12) and maybe prevent paying for negative prices.

I calculate a return after 3Mwh (€650/€0.20€/kWh) of energy.

The return energy logic can easily be build in homey.
So in fact hou only need a device that can module power and is connected to homey.

Any other cheap ideas?

Is anyone able to get the Solyx working via Homey? I can see it, but I can’t control it at a power level.

4

This might have to do with the firmware available on your device: you will need at least version 3.01. If you do not have this version please contact Solyx to discuss options.

5

Might be the case indeed, but where can you find the firmware update?

6

As mentioned, you should contact Solyx if you do not have this firmware version installed.

7

I know, but where can I find which update version I currently have?

8

The firmware version installed can be briefly seen when the Nymo is powered on. I’ve added this information to the startpost FAQ as well.

I do have the same issue, providing the firmware of Nymo is 3.1, the Nymo is not to be controlled by me. Is it possible for the developer to extract my app logs to determine the problem?

I’m running SoLyX Energy Nymo system with Homey Pro, but I’m having trouble keeping it from pulling energy from the grid when heating on excess sun. Whatever flow I set up, it seems to still use grid power. Even one of the flows suggested by SoLyX online is still pulling extra power from the grid.

​If I use the supplied SoLyX P1 sensor, it works fine—it’s only then using my exported energy that my solar panels are creating, as it should.

​Here is the tricky part: because the system is connected to the SoLyX P1 sensor, it can’t be connected to my Homey Pro at the same time, as it only allows one sensor connection. This means other flows I’ve made, like hot water boost or time delays, will not work because the system isn’t connected to the Homey Pro. I’m trying to see if anyone has a flow that only uses the exported energy without relying directly on that sensor? Any help or advice would be greatly appreciated!"

I have Firmware 3.4 but it still is not working properly.Its still just using full power,It takes a minute or two but it slowly builds up to the 3000w that my boiler can take,Even though my solar panels are making no were near that amount of energy

12

You either (in order of probability):

  1. Enabled the the wrong mode in Homey
  2. Set up your flow incorrectly
  3. Have no functional connection with Homey and Nymo

Should be pretty trivial to find out, but we can help you better when you contact us through the official support channel.

Could it be that I am using the p1 meter from homewizard and not the official p1 meter from homey that is causing the problem?
