H50, reading values

[slawomirksiazek]

i'm looking for information if directly from RasPI , can I directly from shell with using some programing language reading and changing values from rego1000 ?
Many thanks.

Hi.
Yes I see that you have ordered a H50 (Raspberry Pi with H1 interface)
The H1 interface supports modifying values in the Rego 1000 (see development manual downloadable)
You can login to the H50 and modify the Python script if you like to log to you own database, make a web interface or other things.

Hello Peter,

yes I bought H50 , my main goal is to integrate installation photo-voltaic PV (solaredge) together with heat pump, I try find ways , as much as possible use electricity from installation PV to current need at home, because in Poland , electricity tariffs for PV installations, are not too favorable for consumers, so my idea is to increasing temperature at home, when PV installation will generate electricity (during the daily peak or something like that), at this moment I know that part of the information, and I can collect part of the information from solaredge webportal through the API

www.solaredge.com/sites/default/files/s ... ng_api.pdf

and my missing part are related with IVT , what exact can I change via H1 interface ? I believe that changing temperature in rooms and DHW for me should be enough, all of this things are possible ?

Many thanks for advice.

Hi.
If you like to manipulate the controller and bring up the temperature for certain periods and bring it down for other you should automate the heatcurve adjustment, or indoor temperatur.
You can set heatcurve and indoor temp by sending commands to the interface via the pythons sccript (or other programming language).

Hi Peter,

Do you have some part python code or exact command which I need to sent to interface, which realize changing heat curve or indoor temp ? I will appreciate for tips,

Yes I can send a sample code to you

[slawomirksiazek]

Ok, Thank you Peter, I will wait,

Yes I can send a sample code to you

I am also interested in some samples, parameters that can be set with the python sccript.

If you like to get a copy of the Python sample code, please send me an email och use Husdata.se contact form.
Thanks.

Hi Peter,
Can you add possibility to send current some basic values directly from you python script to MQTT Server?
Many thanks.

I don't understand that request. Please explain.

[slawomirksiazek]

Hi Peter,
I thought about request to you, that your python script (statlink.py), should allows send current values like:

High Pressostat = XX
Low Pressostat = XX
Heating cable = XXX
Crank case heater = XXX
Alarm = XXX
Pump Radiator 2 = XXX
Add heat status = X %
Warm water setpoint = XX.Xc
Heating setpoint = XX.Xc
Heating setpoint 2 = XX.Xc
Room temp setpoint = XX.Xc
Room sensor influence = XX
Heat set 1, CurveL = XX.Xc
Heat set 2, CurveR = XX.Xc
Heat set 1, CurveL 2 = XX.Xc
Heat set 2, CurveR 2 = XX.Xc
Hot gas / Compr. = XX.Xc
Brine out/Condenser = XX.Xc
Hot gas / Compr. = XX.Xc

directly from script to MQTT server (like mosquitto), I believe that for many users it will be great possibility to integrate your solution with home automation like Openhab or Domitiqa
Many thanks
