 I have noticed a failure of automatic bypass while working with opentherm protocol. When opentherm is connected to Brink Renovent HR the automatic bypass is always closed despite that U4 and U5 conditions are met. Even if you manage to open it (opentherm not connected), then ~ 30 secondes after connecting opentherm bypass is closing despite that the system message informs that the bypass is open :-(

+I have elaborated the following workaround (included in the Brink_HR_bypass2.ino and file):
 
-(*) when bypass shall be open (U4 and U5 conditions are met) opentherm is connecting to Brink Renovent HR periodically
+(*) when bypass shall be open (U4 and U5 conditions are met) opentherm is connecting to Brink Renovent HR periodically ("periodic connection")
 - parameter *readPeriod_bypass* shall be set to 20 seconds minimum(20 000)
 - in the program I have set up 2 minutes for this parameter, which means that every 2 minutes your info about Brink parameters will be read from Brink  and updated in openHAB
-- writing/changing values in Brink are on-line (but you may need to wait until a change is visible)
+- writing/changing values in Brink are on-line (but you may need to wait until a change is visible ins Openhab due to *readPeriod_bypass*)
 
-(**) in such a periodic connection mode you shall NOT control ventilation capacity using ot.setVentilation() methood but only by changing U1 parameter. 
-- it is important to ensure that both parameter U1 and ot.setVentilation() are set at the same level to avoid frequent changes of Brink`s ventilators speed

+- it is important to ensure that both parameters U1 and ot.setVentilation() are set at the same level to avoid frequent changes of Brink`s ventilators speed
+- therefore when the baypass is OPEN and you change U1 (in Openhab) it triggers automatically ot.setVentilation (not included in Brink_HR_bypass.ino)
 - as an example I am attaching my openHab rules in which Brink Renovent flow is controled based on Home Humidity sensor for both open and closed bypass.
