Any ideas for a WiFi thermostat to use?

My home uses a line voltage (120v) system for my thermostats. The overall system has a burner with water circulators for baseboard heating.

I currently have a transformer/relay behind my thermostat to convert from 120v to 24v AC. I can use most low voltage thermostats using the W & R terminals (jumper from R to Rc).

I have tried the Nest Learning Thermostat since that is supposed to work without a C wire. I was able to install it without any errors and I thought I had full functionality. However, with my system, the battery acts as a leach and the circulators will activate without the need for them.

Any ideas on a WiFi smart thermostat brand? Re-wiring is not an option since I would have to open up walls and ceilings. I’m even willing to remove the transformer/relay and use line voltage if one exists for that.

Important note: I’m currently moving away from the Nest eco system to HomeKit.
