### 1/5 — Hodnoceni

*2018-09-22, version 1.2*

V podstatě je aplikace polofunkčni. Prostorova teplota je zobrazovana pouze v celych stupnich bez desetin, nezobrazuje pripravu teple vody,pada pri prechodech mezi jednotlivými castmi ovladaní, při prenastaveni parametrů zobrazi nove nastaveni nekdy az po novem prihlašeni.

### 3/5 — Jen s jedinou chybičkou

*2016-04-15, version 1.2*

Celá aplikace je velmi přehledná a lehce ovladatelná jen ikona okruhu je stále na ikoně topení i když ohřívá jiný okruh.

### 5/5 — So simple

*2015-12-02, version 1.2*
