General Discussion

Welcome to the MySensors forum @shahdad-marri Can you share some more information? What material is the pipe made of? How large is the pipe? Can you open and place a sensor inside the pipe? Is the water drinking water, sewage or something else? Is the pipe oriented vertically or horizontally? Will the pipe either be completely full or completely empty, or can there be varying degrees of water in it? Does the sensor need to be battery powered, or is there access to mains power? Do you have a price range in mind?

@scalz Thank you for the clarification. Is there a way to enable OTA that would be 'n00b friendly'? Perhaps by attaching a small device that can then itself be programmed via the Nano's USB port?

@mfalkvidd thanks for your reply. I had allready read these, but thanks for the links never the less. I have some bluetooth modules (hm-10 & at-09) in the mail. Allready have some i-tags laying around. I will see what i can make of this. My house is only one story so i would like to place one node in the middle of each room on the attic floor. If this works i will have some kick-ass presence detection 😁, if it doesnt i will have some spare ble modules to play with. There just is no down-side to this 😂

I have been using this BLE method (python script) with Domoticz and a couple of raspberry pi zero W. https://www.domoticz.com/wiki/Presence_detection_(Bluetooth_4.0_Low_energy_Beacon) One pi is near my driveway, and one on the other side of the house. I have an old Tile tag in one car and a Nut in the other. Both work fine for detecting when my cars leave and return. It also detects my Fitbit, an old one of the original type. I have that with me most of the time, so it acts like a tag for my presence. I haven't done much with it so far except to turn on the porch light when the cars pull into the driveway at night.

@laoadam Your garage door safety sensors may not be aligned quite right. It could be off just enough that vibration from the door itself when opening and closing is knocking one of the sensor modules out of alignment. The same could be true if one of the wires to it is loose. Check both sensor modules to make sure they are aligned right and not loose. One should be a transmitter that shoots a beam to the other module which is the receiver. If the transmitter beam is not aligned exactly right with the receiver, it won't work. As I mentioned too, check that there are no loose or broken wires. If wires go to screw terminals, make sure those are secured properly and that none of the wire casing is getting pinched in with the wire as that may cause a partial connection that could be lost with vibration of the door. With all that being said, this is a forum for a DIY home automation hardware platform called MySensors. Were you planning at some point to implement this for your garage door?

@electrik said in Quantifying IAQ values of BME680: @nikhil-sukhdev As I read the datasheet, the sensor also provides raw measurements of the gas sensor (5.3.4.4). Perhaps you can use that instead of the compensated IAQ values? I think it's not a good idea. All the interest of the software suite that generates the IAQ is to process nearly meaningless raw values (dependant on temperature, humidity, time the sensor has been running, age of sensor,...) and provide a consistant and understandable value.

Finally! Thanks @Boots33 ! I think mysensors is a great platform but simple tutorials are needed.

@wimd Thanks. Why would I want a non presented node? I am guessing a Mysensors MQTT gateway will let me send and receive MQTT messages direct to/from the Mysensors network without having to rely on Domoticz?

@bjacobse Ok, now i understand, thank you for the link and for a quick reply. Case closed:grinning:

@xefil thank you, happy new year!

@mfalkvidd said in Best way to send nodeDistance and parentNode: @xefil I've never seen anyone reuse a child ID, and I think it would confuse most controllers. Just look at the presentation call: first the sketch would present the child as type X, then the sketch would present the same child as type Y. Will the controller use the first, the second, both or none of the presentations? But you may be right - maybe controllers can handle multiple data types per child id. Well @mfalkvidd maybe it's me that I'm making confusion. AFAYK, in case of HomeAssistant, it has an auto-discovery system which works, even if I don't like the naming convention it uses. BTW, using the above example, subscribing to MQTT server, I can get the values like follow: api doc: MY_MQTT_PUBLISH_TOPIC_PREFIX/FROM-NODE-ID/SENSOR-ID/CMD-TYPE/ACK-FLAG/SUB-TYPE example message published on topic prefix mygateway1-out from node 28, on V_VAR1, which has id 24, becomes: mygateway1-out/28/100/1/0/24 The same way, message published on topic prefix mygateway1-out from node 28, on V_VAR2, which has id 25, becomes: mygateway1-out/28/100/1/0/25 This gives me the ability to subscribe on it and check for changes, like the logs shows me: 2018-12-31 08:37:09 DEBUG (MainThread) [homeassistant.components.mqtt] Received message on mygateway1-out/28/100/1/0/24: b'0.0' 2018-12-31 08:51:09 DEBUG (MainThread) [homeassistant.components.mqtt] Received message on mygateway1-out/28/100/1/0/25: b'1.0' Looking deeper on what the controller recognize it during the presentation, using S_CUSTOM (id: 23) it's reassumed in this part of xml auto-generated: "28": { "protocol_version": "2.3.1", "battery_level": 0, "type": 18, "children": { <code_snipped> "100": { "description": "Internal variables", "id": 100, "values": { "24": "0.0", "25": "1.0" }, "type": 23 } }, "heartbeat": 0, "sketch_name": "node28Studio", "sketch_version": null, "sensor_id": 28 }, So, actually the infos are correctly sent. It's more a matter if the usage of the IDs is correct to avoid further conflicts, if any. That's the reason I'm asking ;-) Thanks, Simon

no, what is it?where can I find the documentation?

By the way, the default baud rate used by MySensors is 115200 so try that if you haven't already.

I just got this to work. It's great! I've updated the first post with a longer guide.

Yes Glædeligt jul :-)

Thanks...it is starting to make a bit more sense of why I may want to use MQTT. Your Vacuum project looks great.

@nickk I changed skins and now I have spyglass search option.
