However...
That antenna IS loaded, so that is probably why the power increase so as to keep the ERP, (Effective Radiated Power), to 100mW...

Great stuff...

Thanks. I've modified my service side to to check the RSSI for two modules, one runs on the balcony (with a wall between the ESP8266 and the WIFI router, and the other in the same room:

Code:

Time: 1580456123 IP: 159.192.XXX.46 0.78:0.91:1.04: RSSI: -58 

Time: 1580456125 IP: 159.192.XXX.46 0.78:0.91:1.04: RSSI: -36

Hope this helps.

PS: Added MAC address to the service side logic as well, because I started testing with both a NodeMCU and a WeMOS D1 (both have ESP8266).

This Blynk app is really cool. I have two ESP8266 devices running and two iPhones with the same Blynk account, and it's working flawlessly. Very impressive.

       --passwordfile	       file containing the domain application server password.

       --terse		       indicates that any output data must be very concise, typically avoiding human-friendly sentences and favoring well-
