Zigbee relay options UK

It's great that it has dry contact and switched live. Good price.
Do the salus trv devices work okay.?

I don't have any of those. The only Salus gear I currently have are some SP600 smart outlets. They work well.

The Salus RX10RF arrived today so I'm testing it out now.

It is discovered OK by Hubitat and the red LED on the unit stops flashing which the manual says means it has successfully joined the Zigbee Network. But neither the Generic Zigbee outlet nor the Generic Zigbee switch drivers operate the relay sadly. Configure doesn't seem to do anything and the On/Off/Refresh commands do nothing.

I wonder if anyone on the Hubitat team (sorry Bruce! @bravenel) could have a look to see if a driver could be made/adapted for this? I would be a really useful device to have working for those of us in the UK.

I'm happy to do any testing on the device that might be required. As far as I can tell the only Zigbee functionality required is to simply turn on or off the relay in the unit.

This the data for the device:

  • endpointId: 07
  • application: 00
  • softwareBuild:
  • inClusters: 0000,0003,FC00
  • outClusters: 0003,0019,FC00
  • model: SAL6DB1
  • manufacturer: Computime

And this is the screenshot from the joining process:

Update. I have just tried the Nue Zigbee Switch driver and that at least sends commands and the device driver page updates it's status to On or Off accordingly, but the relay in the device itself still doesn't respond.

I second that.
Would be a great device to use with the rest of their products supported.

Doesn't look promising unfortunately, looks like they must do their control / data in the manufacturer specific Cluster FC00.

If you change the driver to the ZigBee "Device" one and operate the switches on the front, do you get anything in either of the logs (normal log and ZigBee log)?

No, nothing in either. But then I'm not sure I'd expect to. As I understand it the top switch just switches it between auto (where the relay is controlled via Zigbee) and manual (where the relay is turned on and off by the bottom switch). I wouldn't necessarily expect it to send information about the relay state when it is anything other than auto mode.

I've been reading up more about how it works in the Salus system. There are two different modes it can operate in (changed via a sliding switch on the PCB) - RX1 which seems to be able to receive commands from more than one Salus device on their Zigbee network, and RX2 which only works with one paired thermostat. In RX1 mode when pairing with HE it kept appearing as multiple devices and never seemed to complete pairing, but in RX2 mode the LED went solid red to indicate it had paired OK so that's the mode I'm using at the moment.

I'm wondering if rather than on/off commands it's expecting heat/idle or similar if it's designed to get it's commands from a thermostat?

Or do you think that because it is using Cluster FC00 it's a non starter to create a driver for it anyway? I have no idea what any of the clusters mean to be honest.

It's not impossible, just much harder as it doesn't report that it supports any standard ZigBee Clusters other than 0000 (basic) and 0003 (identity) ..... those two don't do much other than give device information.

FC00 is the manufacturer specific Cluster but unless the device spews out something in the logs then there's nothing to work with (even if it did it would be a slim chance that it matched "something" that looked familiar).

Odd really to choose ZigBee as a protocol and then not use any of the standard Clusters .... their sockets (SP600) are the complete opposite i.e. use totally standard stuff.

You could reach out to the manufacturer and see if they'll divulge the protocol details.

Other than that it would be a case of a ZigBee sniffer and hooking it up to the Salus gateway / devices and decoding the communication to see how it works.

Has there been specific drivers made for the salus Trv or do they work with the standard drivers like the plug?

I will try that but I'm guessing if they've chosen to run a non standard protocol so that it only works with their hub they are unlikely to divulge those details to an end user of another hub.

At least I bought it from Amazon so it can just go back if I get nowhere. It is a good repeater though, checking my Zigbee route table I already have 4 devices routing through it. A bit expensive for just a router but maybe I will hold on to it just in case anyone ever cracks the code.

It seems a great shame and a missed opportunity that Salus have done this. It could have been a useful bit of kit for anyone with a Zigbee hub.

Just tagging the driver guru @mike.maxwell about this. I've emailed Salus technical dept about this just in case they are prepared to give out some info on their protocol. But I don't really know what I'm asking them to give me in any detail. What would we need to know in order to come up with a driver?

A device, that's what we would need...

Not doubting your skillz, but even with what I mentioned above?

Yeah didn't see that post and you called it exactly...

So do we think this is dead in the water then and I should just sent it back to Amazon?

Kinda depends on how much you want to invest in getting it to work.

You'd probably need their gateway and a thermostat to be able to sniff the communications (not sure if it works standalone with just a thermostat, or if it needs the gateway too).

Or maybe Salus will respond positively with some information.

Update. I've just given up and sent the Salus RX10RF back to Amazon. I've had no response from Salus to my email enquiry other than the automated acknowledgment. I tried to ringing their UK office 4 times today and got a constant "all our agents are busy" message every time.

If they ever do get back to me with anything I will post it here.

It seems that the zigbee module does not work as intended. Although the switched live does turn on and off the heating circuit as I planned, it does not create a 'fire up' required.

Unfortunately this demand comes from the rf bosch worcester comfort II controller and it does not matter if I have it permanently on.

Anyone have experience of how to control a worcester bosch controller without using stupid 'smart controllers'?

I might try and remove the rf unit and see if that bypasses the fire on command

hi Guys new here :slight_smile:

I have over 2 year aa Salus IT600 solution with some TRV/thermostat/HUB/windows switches/network extender/relay for floor heating...etc
did anybody try again to connect via HE? I want to use at least windows switches to comunicate with HE but without delete them, or it is possible to connect to 2 different HUB? Salus hub and HE?
a normal windows switch can send a notification to 2 different hub?

thanks ,
