This, honestly, is the best advice. Thank you, @christatt, for suggesting it. On the back of this random stranger’s advice on the Internet, I got myself a few more second-hand TRVs and the Wiser Hub. Most of the house is now zonally controlled and it works better than I could either have hoped or created myself. The HA integration too is just superb.
Why did I not do this in the first place? Probably because I didn’t think buying hardware from the same provider would or should provide any benefits. Anything the Wiser software can do would surely be replicable within Home Assistant, right? Well, no. There’s some clever energy-saving intelligence which seems to do well at using the minimum amount of energy for just the right amount of heat.
It’s not 100% ideal. I’d just finished investing in a solid Zigbee network based on Z2A, which is incompatible with the Wiser kit. I now have two Zigbee networks, each with their own extenders, and that feels like a waste. The Hub itself requires WiFi, which is patchy in that area of the house and seemingly prone to radio noise from the boiler itself. And at the back of my mind is a suspicion that, if Drayton / Schneider had really wanted to, they could have made the Hub and TRVs properly Zigbee compliant instead of extending the standard for their own requirements.
But these are minor niggles. Do yourself a favour: listen to @christatt.
Well - I couldn’t agree more. As the original OP, I actually lost sight of the thread as no-one seemed to be making progress with the iTRVs, so I bought the Hub in June '21 and haven’t looked back. I even submitted a feature-request to the Wiser HA developer to include a Scheduling card/integration - they did and it’s basically completed the setup of using HA and Wiser together as a solution.
Hi, I have a Schneider WISER TRV which is not recognised by Z2M correctly.
I get the messag “Received message from unsupported device with Zigbee model ‘CCTFR6100’ and manufacturer name ‘Schneider Electric’”
Manufacturer unsupported and I cannot use the unit.
Does anyone have similar problems?
Hi all, I’ve had four wiser TRVs for a while now and found that they misbehave frequently with Z2M. Often they won’t respond to a new heating setpoint, and I’ve also had the problem where some of them keep reverting to 20c.
Recently I’ve been using two of them to heat a room in my house using a timer automation in HA, on at 5am, off at 5pm. I noticed a while back that if I restart the Z2M addon in HA then immediately set a new heating setpoint, 99% of the time they will respond straight away. So, I changed my automations to restart Z2M a few minutes before 5am, and before 5pm, and now they are working pretty much perfectly. No reverting to 20c either.
Thought this was interesting as I guess there’s something that changes/gets sent when Z2M restarts that is making them more responsive? I’m absolutely not an expert with this but is that a possibility?
I am running HAOS on RPi4, with a zzh! usb coordinator. Think it’s the source routing firmware as I recall.
I was having issues with my TRV constantly changing between 9.5 and 21.5 on the occupied heating set point. No matter what i did it continued to do this. I got a little frustrated and ended up resetting it 6 times in a row without pairing it any one of the times. Re Calibrating it each time. This seems to have solved this however i will come back and confirm later on today. My TRV is running the firmware version f60f643. I think for the rest of the house i will be purchasing different ones as it is very frustrating with these ones not working correctly all the time even though that is almost a given that that may happen with these kind of things.
I actually removed this TRV and shoved it into a draw for the past year or so. But my z-wave TRV gave up the ghost, so I’ve installed it again. I really didn’t want to keep messing around with this, and realistically without having the hub it’s a never-ending battle. So I’ve just hacked at it, with HA, so that it now works Luckily the TRV is not that loud, so when it “reverts” its settings (every 4 hours or so) I don’t notice the noise, even though this is in my main bedroom.
So I added in a “number” Helper that is now my main Setpoint for the temperature of the TRV. I then added in an automation to help control the TRV. So if the Helper temperate is changed, or when the TRV jumps back to “heat_cool” mode, it re-applies mode to “heat” and takes the value from the Helpers and sets temperature value.
The only thing that doesn’t seem to work well is the reporting of the “current” TRV temperature, I have no idea why, but the TRV itself seems to do a good job overall.
I’ve been running it like this for a couple of months and it’s fine. The odd noise as it resets itself isn’t bad and I don’t notice it now, even when sleeping.
