Hi,
@Logread, could we speak in PM ? I would like to discuss about SVT and a possible evolution for working with airconditioners.
Thks in advance.
You wanted to discuss air conditioning ? Posting this on the main thread as it could be of interest to others.
For now the plugin only works with heating, with the objective of improving over the low quality thermostats that come with most simple heating systems (i.e. electric convectors or basic boiler control). It can only work with on/off systems, bypassing the original controls.
I never ventured into cooling, since most air conditioning systems seem to have a built in control system that cannot be bypassed (at least this is the case in my main home)... if the opportunity to be able to drive a cooler on an on/off basis exists, then the plugin could be expanded to cooling... but I would not be able to test it.
Then there is the additional complexity of fan control... but this is probably secondary.
Hi @Logread.
In fact, i am here more for speaking heating and cooling controls, and more in Energy saving solutions. i am from one manufacturer of control systems, heat pump and aircon.
For Air Conditionners, We have one solution that work with 99% of aircon. of course for first step, it is only for controlling well the aircon by IR. It is base on universal remote control, in the bigining it was used for industrial and commercial applications that ask for a central control system, but for cheap price, and working with different brands... But for now, and smart house, we saw that nothing work really well and easily with aircon. All brand have her own solution, but not a global solution working with all brand, and for easy and cheap price.
We've tried the existing solutions that can (on the paper) work with several brands, but as the RMMini for example or the Zwave to IR, not really easy and good solution for aircons i think.
It si why we develop this during our weekend
But for one easy integration in DIY solutions, as domoticz (the one I use in my own house), i will need help for making a plugin for that. But i need to find a small team for that, i cannot do it alone and by myself, and more send in all public in a thread some confidential and proprietary information of the company.
Second step, i think it is turning SVT for controlling well the Air/Air heat pumps (aircon). Because as all people know, the built in controls are more or less not precize (ex you set 21 you will have 26...etc). For the fan control it is more or less same. The Auto function is more or less bad
.
I know your skills with the SVT plugin. Are you interested in this project?
If there is other ones that know well python or other for making plugins like this, i am here
Also, and for energy saving etc, i think it can be good to add some other points in SVT.
First it is the "presence detection", very easy i think, and with one auto setpoint (as -0,5 to 1°C depending of the heating solution) in relation of the "confort" one. It is what i do now for changement between confort and Eco mode, with temporized presence detection. But with this solution i need to plan other eco setpoint for a real night eco mode for example.
Also, maybe have other setpoint as "Away", and to finish, one "antifrost" mode.
Having it directly is more easy than script etc.
An to finish, maybe be abble to control also some TRV as Danfoss LC13, that in fact, ask to one external real control.
