BMx/BMP rules problem

[mackowiakp]

FW custom compilation based on ESPEasy-mega-20221224.
I have sensor labeled as BMP/BME280 which is in fact BMP280.
There is a strange problem with the EVENT's rules generated by this sensor.
2 devices are defined to support this sensor. Of course, only one of them is enabled at a time.

Also, I only need a pressure reading.
Due to the fact that some sensors can give an abstract result once every few hundred readings (e.g. pressure 3500 hPa), before sending it to Domoticz I check whether the reading is "reasonable". This is done using rules:

Code: Select all

On Temp+Baro#Pressure do
 If [Temp+Baro#Pressure] < 1100 and [Temp+Baro#Pressure] > 910
  SendToHTTP,192.168.0.25,8080,/json.htm?type=command&param=udevice&idx=133&nvalue=0&svalue=[Temp+Baro#Pressure]
 endif
endon

If the BMx280 driver is used, everything is OK and the readout logs look like this:

Code: Select all

3209648: BMP280 : Address: 0x76
3209650: BMP280 : Temperature: 23.78
3209652: BMP280 : Barometric Pressure: 1005
3209673: EVENT: Temp+Baro#Temperature=24.28
3209693: EVENT: Temp+Baro#Humidity=0.00
3209715: EVENT: Temp+Baro#Pressure=1007
3209744: ACT : SendToHTTP,192.168.0.25,8080,/json.htm?type=command¶m=udevice&idx=133&nvalue=0&svalue=1007
3209787: HTTP : SendToHTTP 192.168.0.25 GET... HTTP code: 200

But if the "native" driver for this sensor (BMP280) is used, the reading is not sent to Domoticz and the logs contain the following error:

Code: Select all

747425: BMP280 : Address: 0x76
3747428: BMP280 : Temperature: 23.74
3747430: BMP280 : Barometric Pressure: 1005
3747448: EVENT: Temp+Baro#Temperature=24.24
3747468: EVENT: Temp+Baro#Pressure=1007
3747484: Calculate: Unknown token input: < 1100 and = 0

Whats is wrong? Maybe my mistake or so?

Depending on the build you use, there could have been a warning when saving the device settings that the Temp+Baro name for the device is unsupported. Removing the + from the name will probably improve things much.

Another improvement would be to use the %eventvalue1% event argument:

Code: Select all

On TempBaro#Pressure do
  If %eventvalue1% < 1100 and %eventvalue1% > 910
    SendToHTTP,192.168.0.25,8080,/json.htm?type=command&param=udevice&idx=133&nvalue=0&svalue=%eventvalue1%
  Endif
Endon

(The %eventvalueN% variables will be the value at the time the event was generated, not the current, possibly already changed because of processing delays, value, see: https://espeasy.readthedocs.io/en/lates ... eventvalue)

I thought the old BMP280 plugin was disabled in the current builds as the BMx280 plugin does it all?
Apparently not... however this plugin hasn't been touched for years as I thought it was already no longer available in builds.

I will check later this event as there really should not be any use for this plugin anymore.

This is a Custom build, the plugin is marked as Retired in the Plugin overview

[mackowiakp]

The BMP280 driver is available in ESPEasy-mega-20221224 as _P030_BMP280.ino and I just added it to Custom.h.

The file may still be available, but it is not being used in any build anymore and as I said the file hasn't been updated for years.

OK, THX. Its clear.
