Adding boost #426

Open sandreialexandru opened 4 years ago

sandreialexandru commented 4 years ago

When creating a zone with a maximum operation time greater than 127 minutes, boost does not get added and returns an error. I believe that this is caused by the type of "minute" column in boost table (tinyint). Also, I would suggest that when manually adding a boost we should use some limitation for the temperature and time like maximum boiler temperature and time instead of hard coded values.

Maybe using sliders instead of dropdown lists is easier to implement.

I guess we have never seen this issue as max operation time have never been used up until now

sandreialexandru commented 4 years ago

Leaving out of discussion particular cases, I think that we should create some limitations on boost variables (time&temperature), for security concerns.

pihome-shc commented 4 years ago

i think for safety we should introduce zone running time limit as have temperature limit and use hysteresis_time from zone_sensor table, open for discussion on this one.

sandreialexandru commented 4 years ago

Having time and temperature limits for boost options is a way to set cut-off. Using hysteresis_time column from zone_sensor table as a maximum time limit for boost is a good idea, but it should be renamed. Doing it like this we won't have to modify the database structure.

we already have boost max time in boost table why we need to save it twice? i agree on max zone temperature with slider would be good as zone will never go over its max zone temperature even if user define 400c for boost

sandreialexandru commented 4 years ago

It is like linking everything together. Why would someone be able to set a boost temperature to 400 if the max zone temperature is set at 25? The slider should go as up as the maximum temperature for that zone.

sandreialexandru commented 4 years ago

You are right that time should not be saved twice and maybe there should be just a text box where the user can input time manually, with just a simple html validation for numbers.

pihome-shc commented 4 years ago

but we already have time and temperature cutoff in boost table, i was talking about change from dropdown to slider and leave boost related data in boost table

sandreialexandru commented 4 years ago

I agree. The database would be more organized.
