I’m using ZHA so not sure what i would/could share.
Interesting; I’ll have a look at ZHA instead - thanks.
Good luck, sorry I can’t be of much help. I can tell you that it was way easier to pair just one heating zone than two.
With two zone, each receiver would show two climate entities where only one would actually do anything. So once I found out which controls which I disabled the unless ones.
Hope this helps
@jampez77 how did you get the boiler unit into pairing mode? Is it the pink flashing light or the two amber flashing lights?
it’s the amber flashing lights.
The pink light will just pair it to the thermostat.
Hold down the button on the boiler unit to change the pairing mode.
FYI I found it easier to pair by only pairing the thermostat after the boiler unit has been paired. I had issues when I tried to pair everything at once to HA.
Hope this helps

Many thanks @jampez77
Writing up the procedure for others’ benefit
- Remove the thermostat from the wall and remove a battery
- Turn boiler off, then on again - this should cut power to the boiler receiver
- Hold down central heating button on the boiler receiver until light turns pink then release
- Hold down the central heating button again until the light turns amber with double flashing then release
- Pair (the boiler receiver) with Home Assistant - I will be using ZHA’s ‘add device’ function
- At this point the amber double flash may change to a single flash
- Stop ZHA from searching for devices by pressing back
- Replace the battery in the thermostat and allow to boot
- Press and hold the menu and back buttons, a countdown should appear on the screen, allow the countdown to finish and release when you see ‘welcome’. After selecting a language, it will enter pairing mode.
- On ZHA (or similar), select the boiler device you added earlier, now click “ADD DEVICES VIA THIS DEVICE” - the Thermostat must be connected to the ZigBee network via the boiler receiver we added earlier
- The thermostat should now pair to the boiler receiver. The amber light on the boiler receiver should turn green.
Edit: In October 2024 I had some difficulty re-creating this, the main issue was that the “ADD DEVICE VIA” in ZHA didn’t seem to perform as described and that the battery powered thermostat would be connected to some other zigbee device on the network topology. After much trial and error, I instead used ZHA Toolkit’s handle join action with the device reference field set to the HIVE Boiler’s IEEE 00:1e:5e:09:02:27:d7:90

Perfect!!!
I’ve had a Hive system for a few years and also been interested in the Zigbee query, mostly for fun/experimentation but also to have the possibilty of escaping the clutches of BG’s server. So recently I bought from eBay a boiler controller (Hive SLR2b) to tinker with, not wishing to possibly confuse my real system.
The Hive SLR2b paired immediately with my cheapskate CC2531 easily, no tricks, no fidgeting, no problems. I can send MQTT commands to it and get correct messages back, and nice clunks from the controller as it switches. If Hive Zigbee is a subset, I’ve not yet found what is missing.
Someone clever at zigbee2mqtt has done the hard work; all credit to them.
No excuses now chaps 
Thanks I’ve been wanting to do the same thing and looked on eBay for a cheap one to me about with.
What’s putting me off mainly is how would I recreate the schedule and boost etc as I would lose the hive ones.
What about the hive wall thermostat have you paired that also ?
If so does that still work the same ? As in the built in schedule syncing with HA and the rotary dial.
As it is summer here, I’m using only the hot water, which is just 2 slots/day, unchanged for years. I’ll probably just do this switching with a cron job as being easy for now.
I’m still looking for another Hive wall thermostat for experimenting but I don’t expect any problems with pairing it.
I’m backing away from using HA for this project. I was contemplating doing something with Node-Red as so many wax lyrical about it. It looks like someone has already had a go with Hive and Node-Red; maybe the ideas could be worked into HA.

I got a SLR1b from eBay… as I have a combi boiler so no need of hot water on the 2b…
I paired mine with z2m- it looks like it’s paired correctly however the receiver is now slow flashing orange, and I cannot set the occupied_heating_setpoint - it just reverts to 1C every time I change it or publish the corresponding mqtt topic/payload.
I don’t have a thermosta, planned to use my wall-mounted tablets via Lovelace instead…
Any tips?!
I feel like it might be due to the receiver staying in some sort of pairing mode (waiting for the thermoatst maybe)?
Holding down the heat button on the receiver itself switches between this current mode, and a white flashing light, which does nothing except drops connection to z2m….
Hi @Chiny
Following on from your other post i bought i a thermostat and single channel receiver that i saw going cheap on ebay.
It seems they were going cheap as i think they are older models the thermostat is WPT1 branded British gas but it paired to my zigbee stick ok after i reset it now after pairing it’s just searching …which i presume is for the receiver ?
So the receiver model is SLR1 not SLR1b that i see people use but it looks exactly the same.
I didn’t want to disconnect my working receiver for testing so i’ve wired the SLR1 into a plug and plugged it into a normal socket thinking it would at least power up and let me try the pairing but nothing on the status LED at all.
Doe’s it have to be wired onto the boiler for it to power up as i know it’s missing to common and heating on connections.
Thanks
apols wasn’t replying to you correctly in last post:
I have a SLR1b - I was able to power it on (and pair) in the same way you suggest just using some flex and a 3-pin plug, without any connection to the boiler. My issue is once paired its not working, but maybe I’m one step ahead of you… (without the thermostat)
Oh right that’s good to know…or maybe not good to know in my case as i’m not getting anything from plugging mine in.
Do you know what the differences are between your SLR1b and my SLR1 ? i’ve tried looking online but can’t find anything.
So did you pair yours to your zigbee in HA ? i wasn’t sure how things paired up do the receiver and thermostat pair to each other and then to HA or are they all paired individually to HA
EDIT…
So it turns out my fuse had blown in the plug ha ha.
it has now powered on any synced straight away to the thermostat and the thermostat turns on and off the receiver ok.
But when trying to pair it to zigbee2mqtt it tells me it’s a unsupported device (SLR1)
@Steveuk Re SLR1/1b, it does appear that the SLR1 is not listed as supported but it is hard to believe the differences are great. Worth examining the relevant log for MQTT messages, perhaps looking with the app “MQTT Explorer” perhaps re-pairing as you do so.
@vonagio At the time of my last post, I had only the boiler controller SLR2b (no thermostat) and so had the slow flashing orange LED but that did not stop the boiler controller functioning. If you get white (arguably a pale pink), then you can press the heating button then release to get the slow flashing orange, which is the boiler controller looking for the thermostat. Possibly you could publish an MQTT message from an imaginary thermostat to stop the flashing.
Now I have the thermostat as well as the boiler controller, I’ve got it all working under node-red and everything appears to be working fine, manual on/off, timers, override, replacing all the stuff that BG Hive servers provide. So, it can be done. In my case, I’ll be running it on the bench for a week or so, just to see whether it is reliable, before swapping over to my boiler for real use.
@Chiny Thanks, can I ask when you had just the receiver connected, how did you get the heating relay to toggle? Simply turn occupied heating setpoint up above the local temp, and have the mode on heat?
So on mine, via z2m, it reports a local_temperature of 21C, which never changes. (Not a huge deal as the receiver is in a daft location, I have other thermometers around to use)
It has modes: off, auto, heat.
Ans an option to set the occupied_heating_setpoint to a desired temp…
I’m struggling to find a way for the receiver to actually toggle the relay itself, rather than pushing the physical button… any ideas?!
I’m mostly interested in using this as a simple relay toggle, for now.
EDIT: for clarity if anyone comes to this post - I relented and bought a SLT3 on ebay (£10!). Since z2m has been updated, I’m not sure if I need this but its got high WAF so i’m keeping it. See my reply below for more
@vonagio Head over HERE where someone has been helping me getting my SLR1 supported.
But he is also re writing code for the other ones.

Thanks to Robert Alexa’s work on the converter and readme over on z2m, I now have a perfectly working thermostat with some basic scheduling included. I tried Schedy but it did mad things with a whole range of entities I hadn’t asked it to (including spooky TV/music/light changes at random times!!) so I just deleted it and went with a more manual set up…
Thought I’d share my thermostat package file and lovelace cards in case anyone has similar case needs something similar:
EDITS: handful of edits to clarify some bits incase anyone comes down wanting to duplicate this in the future.

We find we don’t need any additional schedule changes, or different between weekday/weekend (joys of working from home!)… but extra schedule times should be simple enough to implement, and with a workday sensor, and/or additional input_datetime it should be fairly straightforward to make much more complex schedules.
Still to do:
- find a way to set temp based on current/last temperature when turning it on - as manually toggling the heating now reverts to 19C when turned on. I imagine we might never turn heating on/off, except at the end of winter - instead simply setting a lower temperature when away, for frost protection (Hive may automatically do this with its internal frost level? I need to investigate).
- lower the temperature when we leave the house/preheat when we’re coming home. to do this, I’m working on a granular home occupancy state based on our distance from home (eg going for a walk near home = only lower temp a little bit, going to visit friends for the night = lower temp completely, etc etc). Currently my basic away mode just turns the heating off - not ideal when we’re out for the day and its freezing when we arrive home…
Long post, I might have been better to start a new thread!

Great info all this.
You’ve done some great work, I’ve only had chance to skim through it as I’m at work but I’ll be looking at this later.
I still have not actually hard wired my SLR1 in place but it’s plugged into a socket running on a very simple schedule with Node Red.
I’ve been trying to get my head around boost as that’s what my family tend to use often.
So I’m wanting 3 independent buttons for 30/45/60 boost times and I’ve kind of managed it with Peters code in the GitHub link.
On your Hive wall thermostat are you leaving that set to manual all the time and letting your automation deal with it?
What happens if the boost button is pressed on the Hive SLT3 ? Does it actually sync with HA and perform the boost and if so what happens after the boost has ended.
Thanks
