ESP01s boot fails with TX (GPIO1) low #507

This is actually the normal behaviour of the ESP01. No boot with GPIO0, GPIO1(TX), GPIO2 at low. But when I connect TX to a RX Port of a device it is - in my case - pulled low. So no boot. My workaround so far: espeasy with a Transistor switching TX active a few seconds after boot with a rule for GPIO2. Can anything like this be made with esp-link? I really like the slim design and your GUI!! I cannot pull GPIO2 low right away on boot, as in this case booting fails at all. GPIO2 or GPIO0 should be pulled low a few seconds after boot to be able to switch TX (GPIO1) active.
