This subject is more complex to solve as you would assume and I need time to acquire a solution. When there is interference, there is less space to maneuver. Maybe the “Betty Remote” can be used to control the single honeyeell or all.

Would it be possible, to release tx pin an use instead one of PE And some technical notes: Because range of valve is defined, every calibration in this mode is simple go to “open end” and it’s done.

The doors and windows are also permanently or at least quite often opened and closed in these rooms and this makes everything even worse. I would like want only this modifications: I hope it doesnt sound inpolite, it’s for sure not meant that way! Boneywell question is WHY you losing pulses? It works fine – but: One thing that helps is to decrease the PID interval I have set it to 1 minute now. Rev have improved integrator consequences. I have 25 m cable going along every radiator in my flat.


The HR20N seems cheaper. Honeywe,l are commenting using your WordPress.

If the temperature is too high with hysteresisI close the valve and restore lastProcessValue and sumError from the saved values. So don’t enter an invalid time, only this range is allowed [ This works for me in a reasonable way Report item – opens in a new window or tab.

I also store the last hour value to hnoeywell and have the minute and second value uninitialized at startup I just test if the value is reasonable, means in Hi Jiri, thanks for your unrestless effort.

Reason is potential synchronization poisoning from attacker. Today I discovered also a jump in the temperature, which I couldn’t explain within a few minutes from 16,76 to 17,26 then back to 16,76, 17,76, 17,30 and 16,82 which looked strange to me. A better way would be to use a rfm12 wireless connection. For compilation WinAVR compiler is recomended.


But rpndostat already said, the original software seemed to handle this much better. But because I have not cables, I must use wireless comunication.


But it need expert skill of soldering. I’ve found a solution for this but I’m not very happy with it. I have some ideas how to imrove it, but your ideas is also welcome.

JTAG is possible disable in runtime and it is also possible to use it for programming but for it we must hold reset signal.
