Hi firstly i love this extension, i have a EU version of wiser with two actuators for electric radiators.
i have two actuators, one in living room with the roomstat, one in other room alone.
in this other room i don’t have roomstat, but a xiaomi temp sensor connected to HA.
on the wiser (schneider) app, the living room is fully controlable with roomstat, however other room don’t appear bc no roomstat inside…
my question is: can i trigger other room actuator, with temperature data provided by my xiaomi sensor ?
on HA when i try to switch from “off” to “heat”, i have a error 400 unknown from my wiser gateway, certainly bc he’s not appeared with any roomstat.
can the latter work alone, as a “simple” contactor controlled by HA throught the wiser zigbee gateway?
Eco Mode switch is enabled and AFAIK it is a global setting and not applied to individual zones/climates.
I also see this in the attributes: preset_mode: EcoIQ which is odd as that is not one of the valid preset values.
I SUSPECT that when you call the preset to cancel all overrides on a specific climate, the ECO Mode that was set previously by switching the global ECO Mode Switch on gets removed.
I believe this isn’t possible when connected to the wiser hub. The actuators require external temperature measurement in order to work and the wiser ecosystem only has the room thermostat which (imo) is their weakest product due to its very high price point. Having said that I managed to find a bundle on a black Friday sale one year which included trvs. The deal was so good, I resold the trvs on eBay which meant I only ended up only paying about £5 for the room thermostat.
Alternatively the heating actuator is supported by zigbee2mqtt (Schneider Electric CCTFR6700 control via MQTT | Zigbee2MQTT). This would allow you to use you Xiaomi sensor but may not be worth it if you don’t already have a zigbee2mqtt server set up with an existing ZigBee network.
You have the hub Eco Mode setting on - which is a global hub setting. It shows EcoIQ when the room is affected by Eco Mode. If you download the diagnostics, you will see some rooms SetPointOrigin showing fromEcoIQ. This is not a preset mode but a state of the room on the hub.
I do not know how the hub decides that its state is from EcoIQ but that is what this is showing.
@jamiebennett , its been mentioned here a few times, one issue with the wiser system is the location of the temperature sensor. Being on the trv is good in many cases, but often out by 1-2c. The best place is around 1m from the floor and we can achieve this by using the roomstat. the issue is the room stat is quite pricey.
Is there an enhancement product request for a device which is just a temperature device, no display. ?
It an algorithm based on the thermal model of each room. EcoIQ manipulates the actual set temperature based on its knowledge of what the room temperature currently is and if it will get to set point with or without help from the boiler/heat pump/heat source.
This does not look right to me, all of the other rooms the boiler is hardly on, but in the kitchen, the boiler is on all the time, and the temperature never floats up above the set temp as it does in other rooms.
Agree, doesnt look right. From my experience the rad should be hot to touch at the start of heating phase… It needs physical inspection to be honest, might be a sticky valve… they do eventually die
The actual temperature plot 18:00 - 22:00 looks suspciously flat IMO. Maybe the hub lost contact with the iTRV? Also, what % demand is reported for that TRV/climate entity over that period? If it never reached 100%, would suggest to me the TRV was not requested to fully open by the hub.
It is hard to believe the real world temp actually plateaued immediately from such a steep gradient.
You can’t really look at these issues in isolation. Seems to heat up at a good rate then plateaus. That would say to me something is taking the water flow away from this rad. Do you have other rads coming on at about 18:30? If you have new ones, did they all get balanced properly when installed?
On a smaller note, also the rise in temp @ 12:30 is odd if no demand from this rad for heat - unless there is another heat source in this room.
how about doing a little experiment. When you know no other rads are sucking water (Mark has a good point there),BOOST it and monitor it…If it heats up nicely, then bounces above/below the target temp, then that fits with Marks comment… However, i think you said no other rads were on then didnt u?
