using Domoticz with on/off relay from Honeywell BDR91

Post by snk67 » Sunday 02 September 2018 23:33

Hi all,

After some search in here and on Google, could not find a relevant doc about this topic, so better to ask.

I have and already installed Honeywell BDR91 (on/off relay for Boiler) and want to control this via Domoticz. As it was working with 868Mhz, I recently installed a RFLink 868 Mhz Gateway (from Nodo) to Domoticz but I cannot detect the relay. Try to manually on/off it via the button but still not seen by Domoticz.

Anybody using such a configuration? Am I missing something? I am a bit new on Domoticz so any pointer is much appreciated.

As OTGW is out of stock on Nodo I am for now stuck with BDR91. If there is any alternative OTGW that I can install that can also be a solution.

Some details in case it helps to understand what I am trying to do:
- Bolier is Remeha Calenta
- I want to control the boiler to start / stop heating
- I have temp sensors in each room and z-wave controlled radiator thermostats. So based on room temperature and desired temp set on the thermostats, I want to start boiler and adjust the thermostats for each radiator to heat / not to heat rooms.

I am open to any idea or any LUA script that I can use as a sample / starting point to achieve my solution ;-)

Thanks in advance and kind regards.

I believe that the those can only be controlled by honeywell thermostats Im afraid...

However.. Honeywell thermostats can be controlled by domoticz. So one option would be to get one of those to go with your relay. If you cant return your relay and end up going with another solution.. drop me a PM - I need a BDR91 and might by it from you.

Best,

Dan

Apparently (as I registered to the forum yesterday), it does not allow me to DM. @DanM can you sent me a dm so I can reply ;-)
