[APP][PRO] VThermo

it seems that this option is not available with the sonoff, i don’t have these devices myself so i don’t know what to do now. what you could do is make a virtual heater and when vthermo switches this device on you switch the sonoff via a flow.

thanks I will try this but things are getting really complicated just to have a basic heater

  • i need a switch to operate the change of mode on my heater
  • I need a zigbee thermostat
  • I need a vThermo and now I need a virtual device to emulate my switch
    Can someone point me to a better 2 way relay instead of the SOnoff that would offer the option (to declare natively as heater instead of light) maybe, and ideally if it offere the option to reverse on/off status (but I’m being greedy)?
    Which one are you using Glenn?

Thanks

I just tried to create a vurtual device, I don’t see any option to delcare it as a heater, am i missing something? Maybe there are several ways to create a virtual device? i go inot add a new device and type “virtual” in search box, then it shows “virtual devices” with 3 options (virtual switch, virtual IP camera, virtual plug, nothing about heater)

Add a socket and then class that one as heater

And then just two flows, one for off and one for on😇

@Chrys Afaik it’s not possible to exclude specific thermometers.
Some suggestions to work around this:

  • put the window thermometer in a different zone…. (Suspect that’s not what you wanted to hear)
  • change the temperature calculation method (in advanced settings) to “maximum” (which should be the thermometer you want to measure, but maybe in summer or with radiator on not ok)
  • change the temperature calculation method to “manual”, which I suppose gives the possibility to set this by flow on change of temperature of the main thermometer (best solution I guess)

Hello Glenn (and friends), thanks for your precious help

I have created a virtual device, and indeed it seems to work (Vthermo is able to control the actual heater).
I am struggling with something which is probably quite basic but I don’t find it so obvious.
The problem is not Vthermo itsel now, but how to control my heater through the vurtual socket (declared as a heater).
When I do a short click on the virtual socket it switches from actived

to deactivated

I guess since this is a socket it should mean the socket is on / off, although i have decalred it as a heater (so maybe heater is on or off).
But when I open the button (long press on button), then I have this page with a single button (on/off icon)

when I click on the button it turns to black for one second and then reverts to white automatically)

Also when I try to create a flow, the only option availabl when i select the virtual sockek is when activated (not when pressed, which i have on other virtual device)

When I try to create 2 flows to control my heater, the first one works well, the second one does not work (it performs 2 actions to come back to initial stage).
Probably not very clear, but I’m quite lost

Thanks

Olivier

PS: I just changed the type of vurtual device to lamp and the behavior is what I expect when pressing the button if goes from on to off, without reverting back to initial position automatically.
I was able to create the 2 flows to control my heater, it works perfectly.
But then since I do not declare it as a heater, it is not working with Vthermo…

silly me, I think I go it. When it switches back automatically it’s actually Vthermo stepping in, forcing the virtual socket to stay in the righ position to actually do what it should!!!
I will do further tests tomorrow but I think it’s all good

That’s exactly what is happening👍🏻

Good afternoon. I sure Vthermo successfully in my bathroom to control the temperature with a Eurom sani wallheat. The thermostat of this heater is far off though and thus unusable.

The thermostat of this heater is set by Vthermo to 2 degrees higher than the temperature sensed by the sani wallheat whenever I request a higher temp via Vthermo. This results in the sani wallheat to use half power.

I would like that Vthermo sets a higher offset to the heater forcing it to heat with full power. Is this possible?

Hi.

I like the controller, good work.
What I still miss:
It is orange when it heats up and blue when it cools down.
It would be great if the grey colour stayed when it is within the hysteresis and not just when it is exactly at the temperature…

@Spart The colours are homey standard for thermostat devices. Homey isn’t aware of hysteresis values of VThermo, so I guess no change this can be implemented

Thank you very much for a pleasant and valuable app. I use it for both the heat pump, via Tado IR, and for the underfloor heating in the kitchen. I’m unsure if I’m thinking correctly, but it seems like VThermo shows “heat on/off” precisely at a certain temperature, without considering the hysteresis. This makes it difficult to test flows and similar operations. Normally, “heat on” should be displayed when a certain temperature is reached, but the command to activate the heater doesn’t occur until the hysteresis is reached. A thermostat manages the hysteresis and should reflect that - like an old thermostat with bimetallic action, for example.

I’m also uncertain about what happens when you activate and deactivate VThermo. Does it send “heater on/off” in connection with this? If not, it would be desirable. When using the on/off method, there’s a risk that the heat won’t turn off when you deactivate it, and similarly, it won’t turn on when you try to activate it. I might have interpreted this wrongly, but for safety measures, I have handled this in my flows.

yep after testing for a couple of days I can confirm this is what s happening, so all things are good now, thanks a lot for your help.
The only thing I would like to achieve is to get rid of the virtual device (hard to explain to my wife there is now a device in the room she should not use).
Can anyone recommand a Zigbee 2 way controller that manages device type (heater) as unfortunately the Sonoff does not handle it.

Thanks

PS: Big thanks to the developer of this sleek, beautiful and useful app (it should be part of the core Homey in my opinion)

if anyone is looking for the same think, here is a link I got from another thread for a 2 way controller that handles the device as a heater natively

not tested myself yet, but I have ordered it in order to get rid of the virtual device

Al my switches (xiaomi aqara, ikea tradfri, shelly and some others) have the ability to do this. I think its bad luck that the sonoff doesn’t.


I don’t exactly know what you are trying to explain here but there is an offset setting in vthermo.

Thanks. I’m trying to achieve the following.

For example the temperature is now 14 degrees. Now I demand a temperature of 20C. My sani wall heat is indicating 14 as well and is set to 16 by Vthermo.

The wallheat determines it’s power by the difference between the sensed temperature and the set temperature.

Since the Vthermo keeps setting the wallheat’s thermostat to two degrees above the wallheat’s own sensed temperature as long as the Vthermo demands heat, my wallheat keeps working on half power.

What I would like to influence is the offset between the heaters own sensed temperature and the heaters thermostat when the Vthermo demands heat.

I hope I made myself more clear.

Hi all! First of all, great app!
We have a new bathroom and our ventilation is sometimes kicking in too late (it has a humidity sensor) since we moved our shower to the other side of the vent duct. So I placed a sensor right above the shower cabin to pick up some first signs of humidity increment. So far so good! Easy to set up, but I’m just guessing with these humidity % points. Can someone guide me in the right direction? Because it doesn’t seem to stable. Thanks!

Hi :wave:.

I’ve got four battery zwave TVRs. Two in one room, and the other two in other rooms on different floors. That makes three zones, in different patent zones.

To call on the water to the radiator I have a fibaro double switch connected to the central heating pump.

What is the best way to call the heating pump when any of the TVRs call for heat?

(The TVRs are Aeotec/Eurotronic/Spirit)
