Transmitting to unsupported device (Nobo heater)

Hello,
Currently I have my home equipped with the Nobo heaters that are controlled by Nobo hub using wifi to connect to the heaters. The system can be controlled using either a phone app or a Nobo wifi remote that connects to the hub. The remote is basically a four button switch powered by a CR2032 battery: Schedule, Home, Away and Vacation, which are four profiles stored on Nobo hub.

Nobo system does not have integration with any home automation systems and I am wondering if there is any workaround.

I would like my home automation to be able to switch Nobo between Schedule and Away states.

I was wondering if this can be done through any of the following:

  • Sniffer. I know, that e.g. 433MHz signal can be sniffed by Broadlink RM Pro+. Is there a similar wifi sniffer that can mimic a signal sent by Nobo remote (most likely not, though, because it is not about sending a wifi signal, but sending a signal to the Nobo hub that it would accept)

  • ammending Nobo switch with several receivers soldered to the respective buttons. Once home automation hub sends signal, a receiver should short the circuit of the respective button briefly, thus emulating button press. Notably, I do not need any feedback from Nobo to to the home automation hub. So, one-way receiver should work.

Hence, do you know of any receivers that can do the job? Obviously, the receiver should be self-powered/externally powered, since it cannot be powered from the Nobo switch.

Thank you.

I also have Nobo system, with their proprietary hub.
I am also very dissatisfied with it, even apart from the fact that it can’t be integrated with anything.

The HUB doesn’t get any information about the temperature measured at the various rooms, or when the heater panels are on or off… no info about consumption, hours of operation, etc.

My plan forward is to install an independent temperature sensor network (to collect temperature info), and install Shelly 1PM relays/switches before each panel. In the first phase of the project, this will allow me to monitor usage. In the next phase, I will just set the NOBO hub to an impossible to reach target value (therefore hard-wiring the fancy radio controller to ON), and will use the Shelly switches to power on and off the device, based on the info collected by the independent temperature sensors.

This will make the whole NOBO control system totally redundant.

I wish I have never had purchased it in the first place.

Csilag, I agree Nobo is very far from perfection and I would also love to have relay for each panel. This, however, may be impossible in my case: my electric heating is powered by 400v power supply and I am not aware of a reliable relays to control 400v devices. What is your setup? Are you using 230v panels?

Yes. I am using simple 230V panels, connected to normal wall sockets.
(I installed some dedicated wiring beforehand, because of the anticipated load of the ~10kW by the 10 panels or so.)

For anyone that stumbles onto this old thread, this can now be done with this HACS integration:
