There are options for hydronic and electric UFH available for Wiser in the UK now.

939

yeah i saw those straight after I posted … :slight_smile: Currently I only have radiators…

Quite like the electrical heat switch but presumably for a towel rail in a bathroom you’d need its own room stat? Is the room stat good for a potentially humid environment and even if it is it’s a significant extra cost, again a simpler non display stat would be better.

941

If you are all water based maybe https://wiser.draytoncontrols.co.uk/underfloor-heating-controller will help? Electric then https://wiser.draytoncontrols.co.uk/electrical-heat-switch-and-remote-floor-temperature-sensor.

The switch is IP44 rated and is safe in moist environments like bathrooms (away from direct water ingress), the room thermostat is IP20 so recommended for outside of areas where moisture can build up in any significant way.

942

I think you actually need one of these:

I am looking at this as a possble way to control the immersion heater in the hot water tank, in case of a problem with the boiler. Unfortunately, it doesn’t seem to be available in the UK anywhere. The only place I have found to get it is from a French website:

I don’t know if anyone in this thread is from France and is able to vouch for the reputability of this website? I was thinking of buying/importing one until the disconnection problems with the hub started, so am holding off for now while I investigate that further. I assume it works with the UK Wiser hub. Maybe @jamiebennett could confirm? I suspect it will be a case of yes, but it’s not supported, which would be fine. It’s Zigbee anyway, so I could always connect it through Zigbee2MQTT.

943

This is the same heat switch Jamie posted above. Just fyi, this is already integrated into the integration along with the UFH controller Angelo is excited about, as we had help from some people who already had these.

They may need improvements as i dont have them to know what is needed but should at least work ootb.

Ah. I didn’t realise that was the exact same thing. OK, good to know it works. Does anyone know anywhere you can buy one in the UK?

Actually not to worry. Now I’m searching on the correct name (as it’s referred to in the UK), I found it here:

945

Carl, this is basically a switch so you could use any temp sensor and have an automation in HA manage it. Not as slick as being fully integrated into Wiser with schedules but would work. Thinking about it, you could prob create a schedule ( as you can create many schedules and not assign them to anything) in Wiser for it and (maybe with a couple of mods to the integration), use your seperate temp/hum sensor and a schedule to control it with an automation.

946

That’s an option, although keeping it fully integrated with Wiser makes things easier if you move house and the new owner wants to use it. I’m not sure leaving them with HA would work.

947

The heat switch can be used with a sensor (typically a wired floor temperature sensor) so will track to the temperature reported from that along with a thermostat which sets the desired temperature. This is fully integrated with Wiser, schedules, moments, etc.

948

Regarding domadoo no problem, you have also domomat .

On the other hand, the control module actuator for electric radiator zigbee had been designed for radiator, my last information ( I met a french Schneider Electric guy last week) is that an actuator for the water heater immersion heater should be released in early 2023 ( I’m waiting this device too)

Thanks. That’s good to know. Maybe I should hold out then. Do you know anything of what the differences are? Surely it’s just a 16A rated relay, which I would think would work fine with an immersion heater.

950

I think that it would, I use these heating actuators, they work with climate, roomstat…
The new modules should work autonomously like smartplugs. It will be then fully integrated with Wiser, schedules, moments, etc.

Thanks for the reply. I hadn’t seen the Wiser Electrical Heat Switch before. I assume it must have been released recently as it wasn’t on the Wiser website last time I looked. It does appear to do what I need, although it is over rated for my requirement as the fan in the fan radiator only draws less than 1 amp, which is probably why it’s a bit expensive.

952

Thanks for the suggestion and the work you and Mark Parker put into the Wiser integration.

I purchased the Wiser plug assuming it would be able to be controlled by the Room Thermostat, and probably the TRV’s as well, just by using the Wiser app. I was very surprised to find that it couldn’t. It seemed an obvious use for it.

As it was summer so the heating’s not in use and I have plenty of summer jobs to do I put it to one side to sort out later.

Immediately after I made my post and having read jamiebennett’s explanation of how Wiser handles Room Thermostats and TRV’s in the same room I realised I can use a Home Assistant automation to control the Wiser plug to achieve what I required. I already use other Home Assistant automations with my Wiser system so I don’t know why I didn’t think of it before.

However I still think that the Wiser app should natively allow the plug to be controlled by the Room Thermostat and TRV’s as I suspect that probably the majority if Wiser users don’t use Home Assistant.

Blimey…

So @jamiebennett joins the thread and the entire thread explodes with excitement and posts … COOOOOOOL :slight_smile:

Thanks for the reply.
As already mentioned this is the same as the Electrical Heat Switch suggested by jammiebennett.

I am also looking for a way of controlling my immersion heater by something Wiser, and also Home Assistant. This should be suitable as it’s rated at 16amp and is probably better made and therefore safer than using a Sonoff TH16.

955

Be careful, this switch is not a load switch, it is a temperature switch so needs a thermostat to control it. It won’t be suitable for hot water control at the moment.

Thanks @jamiebennett . It sounds like I need to hold on for the relay for immersion heaters that @LGO44 referred to then. Can you confirm if this is coming to the UK and whether the timeframe is the same as France i.e. early 2023.
