@TimO said in Openhab multiple gateways: @niccodemi yes, you need to use different names for different things in Openhab. Name it as you like. The node id is unique per gateway, so you may use the same node id on different gateways/networks. I have problem with 2 MQTT gateways, mysensors binding prasing only one mqtt topic. Also in new OH2.5 is problem selecting Mysensors Mqtt Gateway.

@niccodemi said in water flow sensor YF-B5: convert flow in l/min to pulses per liter You can; read the example code I pointed to. And as always, Google is your friend

@vanjsy Use the sketch here - you can use it as is (change ssid and pwd of course) or add the missing pieces to yours.

@niccodemi this issue i reported more often in MySenors forum adding a delay (or better wait()) is the solution. It should not be a problem because this presentation function is only called once at start up

@siklosi thanks, so that means this module would be only good for serial monitor? Is it possible to do serial monitoring with mysbootloader / myscontroller? I am currently using serial gw with vera - if I am to use myscontroller do I have to disconnect it from vera and connect it with computer running myscontroller?

Hey there. Sorry for the delay. I never get notifications on this board for some reason. I'm using one of these: http://www.amazon.com/dp/B00EVKVM02/ref=pe_385040_30332190_TE_3p_dp_1 And one of these for my sprinkler 3/4 line: http://www.amazon.com/dp/B00EVKOK6A/ref=pe_385040_30332190_TE_3p_dp_2 http://www.amazon.com/gp/product/B009YVCMX4?psc=1&redirect=true&ref_=oh_aui_search_detailpage I couldn't find the 1" valve to go with the sensor but you get the idea. I'm just switching those with normal relays tied to the appropriate pins. Funny you should ask about this, however. I'm actually not overly thrilled with the flow sensors (especially the 1" model). It doesn't seem to detect low flow rates. Either my sketch isn't sensitive enough (maybe my debounce is screwed up) or it doesn't pulse for lower speeds. I'm considering another type of flow meter but 1) haven't found one yet 2) not looking forward to re-plumbing everything.

@Dwalt oh wow.. thanks so much.. i was waiting for you to get back to me but never saw this post.. and i just happened to stumble on it when i was looking to see if you had been back on the forum or not. I'm good with the hardware side of things and can shell script and do windows scripting. but still have not learned this coding yet. i have all the hardware for the 433 stuff. i even got the RF stuff to work (on my RPI2) and sniffed all my codes i could just never get it to work with my arduino stuff. likely the code, so i'm excited to give your code a go. Thanks!

Still this code is working?

@BulldogLowell thank you, I uploaded it and so far it works fine.

RFduino uses BLE (Bluetooth Low Energy). While this is also 2.4GHz it's not compatible with nRF24L01 in terms of protocol.
