Is there Velbus “approved” solution? I searched the forum and I see some solutions were developed over the years. All I need is a point measurement, 0 to 90 deg C. The sensor will be build into the water heater. I plan to use openHAB, so currently I consider something like ESP-8266 chip with a temp sensor DS1820 (info from openHAB forum), but I’d prefer to have a 100% velbus solution as it seems to be much more reliable that openHAB.
I have fairly complicated control plan, but even having part of it in the velus part of the control woud be great.
Thank you! I need to find some other use for VMB4AN - otherwise the price of the module would be higher than the price of the water heater I’m not yet ready to play with a live system :- someone could get burned
Can you check the link? I tried 3 browsers - no go.
That very much depends on the granularity of control that you are looking for.
you could wait until the NEW " VMB8IN " becomes available, which I’m told will have 8 sensor compatible inputs, all with threshold options and multi alarm triggers. (TBC) update, No, unfortunately the next VMB8IN will only support pulse inputs
When I say a “Live” system, I do mean a fully isolated demo rig.
I wouldn’t want you setting my heating targets to 32ºC in every zone
This openHAB thread has also been updated with extra comments and product links
Thank you for sharing! That looks class - I’ll definitely consider that solution as energy might be “environmentally cheaper” for me than water. With under-sink heater the hot water is instant. With a water tank 10 m away some water is always wasted unless I go for well insulated pipes and constant circulation.
