@fixjunk this configuration will be supplied to your gateway from a controller.

When your MySesnors node boots up, sends a I_CONFIG request to your controller, your controller has to respond to this request [response can be either (M)etric or (I)mperal ]
AFAIK, This metric change will not affect your sensor measurement units. You have to convert yourself in your sketch.
@mfalkvidd can confirm this.
@rvendrame Timely - I haven't put it into operation yet as only just finished the plumbing mods in the pump well for a 5psi water pressure sensor. Because I've saddled the sensor to the pump suction line I'll have to inhibit readings when the pump runs, hence delayed operation.
5psi is equivalent to 3.516m head, so you will measure over 80% of the ADC range giving a resolution of 4.25mm..
My 3,000 litre underground water tank suffers the same issue over condensation when winters drop below -5.
Hope this helps.
Great, that was the right hint. Now I get values. Thanks!!!
But should it included in the example code? I had a look in the development branch. There it was fixed. But in the development -3.0.0 branch not.
I added a new node(ralay id:50), again home assistant(HA) was not added. How can I send a new value from the Relay?
You need to send a message at least once for it to appear in Home Assistant. Use something like this:
bool initialMessageSent = false;
void loop() {
if (!initialMessageSent) {
send(msgRelay.set(currentRelayState));
initialMessageSent = true;
}
}
After you manually injected a message via MYSController, Home Assistant started to list the new entity in the UI. So yes, that's exactly what Home Assistant required. If you take care of that within the sketch as shown above, you don't need to do it manually.
But It seems to be disconnected from the network every time a command comes from HA.
do you think this is normal?
No, I wouldn't consider that normal. What do you mean by "disconnected"? Does the node stop working completely after receiving a message from HA? Doesn't it respond to consecutive commands?
Does the debug output (using #define MY_DEBUG in the relay node sketch) hint at something? Sharing your sketch may help us find the issue.
